Rusty and Iris are Great Horned Owls that are both blind in their right eyes and cannot live in the wild. Rusty and Iris are breeding in captivity as part of Karla's vocal study on Great Horned Owls. All together they have led to the creation of an International Owl Center in Houston, MN and an International Festival of Owls.Karla (Kinstler) Bloemhttp://www.blogger.com/profile/13515204503379188869noreply@blogger.comBlogger276125tag:blogger.com,1999:blog-9725321.post-63736728273104662502014-02-02T16:46:00.002-06:002014-02-02T16:46:39.423-06:00New blog!We have a new blog!

It was a weak signal to boot. Given that we found Patrick's tail feathers with his transmitter on the ground, that's what I was expecting to find for Patience too.<br />
<br />
Hein had already tromped the hillside on Saturday on one landowner's property, with no luck. This morning we went out on another person's property in the snow to see if we could find her transmitter there. <br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJmGDaLQSc9yDTlQExvqJgVTqvqFP_cwKAbvYa2X6zzI0SGV8tfhJ-eeADjSR0yqNXRMU98y8lJZ0vdN-vFjKISF1QI6rN0sr_QuTIGRVFQk3ZweycTvA0C6nRUZOEdLAIZ3uNQQ/s1600/P1110308.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgJmGDaLQSc9yDTlQExvqJgVTqvqFP_cwKAbvYa2X6zzI0SGV8tfhJ-eeADjSR0yqNXRMU98y8lJZ0vdN-vFjKISF1QI6rN0sr_QuTIGRVFQk3ZweycTvA0C6nRUZOEdLAIZ3uNQQ/s320/P1110308.jpg" width="320" /></a></div>
<br />
We didn't even take a bearing on Patience from the road...we just headed up into the bluffs where her signal has been forever. It was a very weak signal, but we plodded along in the increasing snow on the hillside that got steeper and steeper.<br />
<br />
Finally up near the top, out on a point, I got a good signal. But I really, really thought it was coming from across the road in the marsh. So we slowly made our way back down the hillside, to the truck, and to a gas station to use the restroom and get something to eat.<br />
<br />
Then we stopped by the house of the person who owned the marshland across the road and she gave us permission to go out there. That involved wading through a lot of tall grass, but also a nice mowed area.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
It was snowing pretty good. We kept walking toward the far trees, and the signal was still faint...fainter than up on the road. I finally realized that our gal was a long ways away!<br />
<br />
So back to the truck again, and I slapped on the rooftop antenna. We drove down the busy road between La Crescent and La Crosse, pulling into a couple of parking lots to get signals. Very surprisingly, we got a GREAT signal where the old Bikini Yacht Club was...across the road, not out into the river bottom.<br />
<br />
So we headed across the road to Pettibone Park. I chuckled as we drove in, since the sign said it was also a wildlife refuge. I thought that would be a good place for Patience to go. I wondered if she could read.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
As we drove around, her signal got really strong. Finally I got out and walked. At one point in time I thought I must be standing on her because the signal was so loud. Hein was watching the trees to see if she flew, but didn't notice anything. But abruptly, the signal moved. I headed in that direction while Hein went to get the truck. Sure enough, as I got closer I saw her fly. Woo-hoo! She was doing fine, transmitter attached. Not what I expected to find when we set out this morning.<br />
<br />
I checked the state line, and I see she has officially entered Wisconsin. Without permits. I get a kick out of that, since to bring Alice into Wisconsin to do a program I need a health certificate from a veterinarian, a 'temporary wildlife exhibition permit' from the DNR, and a 'circus, rodeo and menagerie permit' from the WI Department of Agriculture. I am not kidding. Go Patience...without the permits!

<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
I have been feeling queasy lately since Patrick and Patience's transmitters haven't been moving. I went out at 7 AM a few mornings ago to scour the bluff with my receiver, trying to locate him. Although I got good signals, I simply couldn't pin it down exactly. This morning Hein and I went out just after 7 AM for another try.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
It's cold, but I realized after last time that climbing snowy, heavily wooded hillsides works up some body heat, so I dressed in lighter layers, but very obviously not for fashion or to look nice in a photo!!</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
We climbed and tried not to let gravity return us to the bottom of the hill, or to the ground. I took very frequent bearings with the receiver (as I am doing in the photo.) Finally, after quite some time, I got to the point where it was so loud and so directional that I had to be just about standing on it. Sickeningly, the antenna beeped loudest as I pointed to the ground.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Hein was on the uphill side, and when I said that the transmitter had to be on the ground, he simply pointed and said "There it is." Thankfully he was not pointing at an owl-shaped bump...he was pointing at the receiver poking out of the snow.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
We picked it up and found it was still attached to the central two tail feathers. I cleared the snow to make sure there were no other feathers, and there weren't. It had simply broken off, leaving Patrick without his middle two tail feathers. (They do this when the molt every year, so it shouldn't be a big hindrance to him.)</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
I was much lighter in my heart as we carefully negotiated our way down the hill. Hein did the "butt slide" part of the way.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOT_jdx_5IVNXEX8iDMgiafla9QATCyL4YdIYDmILWUxYqFO6Fvzw6CW39FETkVTZ6caQRe65atPHY-MWNt1OQ5yoxJm4hhAdQQCS0QWfr6RLWu-YJ08O-9q7tGfvmq82DEnA74w/s1600/P1110293.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="240" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOT_jdx_5IVNXEX8iDMgiafla9QATCyL4YdIYDmILWUxYqFO6Fvzw6CW39FETkVTZ6caQRe65atPHY-MWNt1OQ5yoxJm4hhAdQQCS0QWfr6RLWu-YJ08O-9q7tGfvmq82DEnA74w/s320/P1110293.jpg" width="320" /></a></div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
When we got back to the house we looked at the feathers more closely. Hein said he made sure not to pinch the shafts when he tied on the transmitters, and the shafts had broken exactly at the leading edge of the transmitter's base plate. </div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
I'm guessing what happened is that the transmitter's base plate was big enough that it didn't allow the flexibility the tail feathers needed, so instead of just bending when in dense cedar trees like this, the central two tail feathers kinked and eventually broke off.</div>
<div class="separator" style="clear: both; text-align: left;">

Hein went out looking for Patience later, without luck. I suspect we'll find her transmitter too. This isn't an unusual type of mount, and I think it's used on Peregrine Falcons. But perhaps Great Horned Owl feathers need to work in a different way?? Not sure what happened here. But at any rate, Patrick's free and unable to be tracked, other than his begging calls. He was in the yard begging early this morning again, so I set up the two swimming pools the owlets used for rat catching outside, complete with dead gophers. I hope he figures it out if he needs it.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
We'll try again on Monday on a different landowner's property to find Patience's transmitter.</div>

<br />
Tracking the 3 P's has been a learning experience for sure. First we realized that it was terribly difficult to track the young owls with just a directional (yagi) antenna, as we lost all three of them within one week! So we got an omni-directional antenna that sticks to the roof of the car with a magnet, and it worked so well we found Patrick and Patience within a few hours of receiving the antenna in the mail.<br />
<br />
But despite putting on hundreds of miles driving in every direction from Houston, we've been unable to locate Pandora. The only other option was to go up in an airplane to give better reception range, and thankfully flight instructor Dale Scobie agreed to take us up.<br />
<br />
We got a bead on Patrick before we left for the airport, so we'd have some kind of baseline to determine the range of the receiver in the airplane. I got faint beeps from Patrick as soon as we were up in the air in Caledonia, over 12 miles away!<br />
<br />
<iframe frameborder="0" height="350" marginheight="0" marginwidth="0" scrolling="no" src="https://maps.google.com/maps/ms?msa=0&msid=203835038911858411720.0004ead39064d8c3a899a&ie=UTF8&t=h&ll=43.794889,-91.579285&spn=0.69389,1.167297&z=9&output=embed" width="425"></iframe><br /><small>View <a href="https://maps.google.com/maps/ms?msa=0&msid=203835038911858411720.0004ead39064d8c3a899a&ie=UTF8&t=h&ll=43.794889,-91.579285&spn=0.69389,1.167297&z=9&source=embed" style="color: blue; text-align: left;">Pandora, Patrick and Patience Locations</a> in a larger map</small><br />
<br />
We essentially flew a large circle around Houston, periodically stopping to make small circles so the directional antenna would pick up the owls no matter where they were. We went west to Lanesboro, south almost to Mabel, east to the Mississippi River, and north to Winona. We covered a large area.<br />
<br />
Patrick came in loud and clear anywhere to the south. Patience, always checking out new places, had tucked herself into a little valley so her signal was only good when we were within maybe five miles.<br />
<br />
But as much as we tried, there was absolutely no signal from Pandora.<br />
<br />
So what does this mean? Either her transmitter is no longer anywhere in the area, it has stopped working, or it was destroyed. Even if Pandora had died her transmitter would still be transmitting. At this point there is no way to know, so you get to choose your own ending to her story.Karla (Kinstler) Bloemhttp://www.blogger.com/profile/13515204503379188869noreply@blogger.com4tag:blogger.com,1999:blog-9725321.post-1396728848181195482013-11-27T09:41:00.000-06:002013-11-27T09:42:41.243-06:00What's going on? 11-26-13<iframe width="500" height="281" src="//www.youtube.com/embed/5Tb8QlJwlho?rel=0" frameborder="0" allowfullscreen></iframe>
Although Rusty and Iris were successfully hunting and killing rats in the flight pen when the owlets were still there, mice seem to have complete and total impunity in the breeding pen. Here's a field mouse running around all over the nest again. Are these mice pets or what?

<iframe allowfullscreen="" frameborder="0" height="375" src="//www.youtube.com/embed/wHIh6nr9kQQ" width="500"></iframe></div>
<div>
<br /></div>
Iris definitely missed Rusty when he had his eye surgery and was recovering in a dog carrier for nearly a week. Rusty still heard Iris over the monitoring system, and he always hooted back immediately whenever he heard her. He also hooted back when he heard Alice, which certainly startled Alice to hear Rusty IN her house!<div>
<br /></div>
<div>
In Rusty's absence Iris had to deal with Rhett and Delilah's nightly intrusions. Besides hooting on and around their aviaries, Rhett and Delilah figured out how to get INTO the open flight pen. The door had been left open so the owlets could return to mooch food if needed, but they didn't.</div>
<div>
<br /></div>
<div>
It seemed a long wait to get through Rusty's medication dosing so he could go back with Iris. I was only too happy to close the outside door to the flight pen to prevent the wild owls from coming in and to put Rusty back out there. He was disoriented at first, probably from a combination of being in a dog carrier for almost a week and from the effects of missing his right eye. Their eyes are huge, so missing that much weight on one side of his head could easily affect things. </div>
<div>
<br /></div>
<div>
Rusty didn't fly much once he got up onto a perch, but he did hoot some, as did Iris.</div>
<div>
<br /></div>
<div>
It wasn't until the next night, after Rusty had eaten his last pill-laden food, that I could open the door between the pens so Rusty and Iris could be together again. And what a happy occasion it was!!</div>

Rusty is in captivity because he was hit by a car and left blind in his right eye. His bad eye has been bothering him lately, though. A vet checkup led to a determination that his bad eye needed to be removed. He had a large corneal ulcer, dislocated lens, and a big honking cataract. His eye pressure was normal, so we were given the option of no surgery and trying to treat the ulcer. This would involve catching and treating his eye three times a day for two weeks. No guarantees it would work, and the cataract could still cause swelling and issues in the future. We decided surgery to remove the eye would be far less stressful for Rusty, and would certainly take care of the issues.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
We were anxious to get the surgery done so Rusty could be feeling good for the upcoming breeding season. He and Iris normally start copulation by mid to late November, so that time is essentially upon us!</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
The day of the surgery we caught Rusty up, put him into a dog carrier, and drove him 2.5 hours up to the University of Minnesota Veterinary Medical Center in St. Paul. We caught Rusty up and left at about 8 AM.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Dr. Henriksen and her staff were excellent to talk to. Drew from The Raptor Center assisted, since they don't usually handle raptors at the Vet Medical Center. Needless to say we didn't get to stay for the surgery, but they did take photos for us and got special permission for us to post them. Thanks!!</div>

Since owl eyes are so huge, you can see the side of them in their ears. Because of this the incision to remove the eye was made from the ear over to the eye. The surgical site had to be plucked of feathers first. I think owls look a LOT nicer with feathers!!<br />

I do have photos of the surgery itself, but I won't post them because I think most people wouldn't want to see them. The photos show how they held the eyelids open, the eyeball itself coming out, and sewing up the large gaping hole. This is a major surgery for an owl since one eyeball is about the size of its entire brain. That's almost 1/3 of the stuff in the head being removed. Dr. Henriksen said owls will sometimes hold their heads tilted after eye removal surgery.</div>

We kept him in the carrier overnight. He didn't eat anything and thumped around some. In the morning I switched him to a larger carrier and quick snapped this photo. Looking much more handsome than the last photo!</div>

Tonight he needed his first dose of antibiotics and pain meds from us (he got them at the vet's the day of surgery.) Hein held him, I put his pill in his food, and I fed him bits of food. He ate VERY well, although Hein's sweatshirt got a nice amount of gopher blood on it (and Rusty got some blood on his bib. Owl bibs aren't made for blood....) He was full of spunk, but took his meds like a good owl.</div>

<br />
Now that the owlets are out and on their own, I'm leaving the door to the flight pen open for a while. This is so I can still put out food on their regular feeding tray and they can come and mooch if needed. So far no takers, although Patrick was back in the neighborhood for a bit this morning.<br />
<br />
So with the door open, I'm hoping that the wild owls will make an appearance. Tonight we had a heck of a hootenanny going on with Rhett and Delilah in the yard, Alice hooting in her outdoor patio, and Rusty and Iris going nuts trying to defend their little territory.<br />
<br />
I knew it was going to go on forever, so I left since it was time to make supper. As I was making supper I kept peeking at the cams, saying "One of these owls simply has to go into the flight pen!"<br />
<br />
So when I got back on to my computer after supper, I saw that critterwatcher had sent me a photo of an owl standing in the open door! Whoa!!!! So who was it? I can only tell by voice, not by seeing them, so I immediately pulled up the video. Thankfully the owl in question hooted repeatedly: it was Delilah!<br />
<br />
After I went to bed at least two owls came INTO the flight pen. I haven't had a chance to review and figure out who it was, but they didn't eat the gopher on the food tray.<br />
<br />

<br />
The day finally arrived for the owlets to fly the coop! My criteria for releasing them was that they had to have developed their full adult hoots and could hunt respectably. At nearly 8 months of age, they were there.<br />
<br />
Bob Anderson and Amy Ries of the Raptor Resource Project had come a few days ago and put the transmitters on the owlets' tails so we could track them using radio telemetry. We held them a few days to make sure the owlets didn't have any issues with their new "bling", and they didn't even seem to notice them.<br />
<br />
Friday, November 8, 2013 was THE DAY. I wanted to send them off with full tummies, so I fed them at 5 PM. I wasn't going to give them any live rats that night, since I didn't want rats running around in the pen with no one to catch them if they weren't all eaten immediately. But I caught a few deer mice in a live trap that day, so I plopped them in the flight pen along with the big chunks of pocket gopher.<br />
<br />
The owlets went for the mice first, then ate their gopher, just as I had hoped.<br />
<br />
At 7 PM, the appointed hour, I got onto chat, along with Hein, and did a little talking about the project, goals, and what we've all learned. (I can't resist giving a little "program" when I have an audience of over 100 people like that for such a momentous occasion.)<br />
<br />
Then finally Hein and I put on our jackets and headlamps and headed outside. Hein had two ladders already stashed at the far end of the flight pen by the exit door. He set up the wooden ladder for me so I could climb up and unlock the door and open it. On my way up one of the rungs snapped. Thankfully I didn't have much weight on it. I guess that's what happens when you store a wooden ladder outside with one side on the ground! (The ladder was originally bolted into place by the exit door, but we took it down to prevent animals from climbing up it.)<br />
<br />
So Hein set up the folding aluminum ladder for me and up I climbed. The padlock was easy to unlock, but the door took a little tugging to get open. Bear in mind it hasn't been open since the building was built three years ago!<br />
<br />
I climbed down and Hein took the ladder and put it up on the other side of the door. He needed to install a new hook to hold the door open since the hook originally installed was bent open and wouldn't hold. He had all the tools so it went fairly easily, but while he was getting set up the first owlet flew out! That was unexpected, but the girls sometimes just fly around not knowing what to do when they're scared.<br />
<br />
When we finished we simply laid the ladder down and walked away. As we were leaving girl #2 flew out. These owls flew out in fear, I'm sure, not because they were curious and ready to go.<br />
<br />
So we went inside to assess the situation. A sweep of the cam revealed Patrick snugly tucked into a hide box on the wall as faaaaar away from the exit door as possible. He was staring out the open door, wide-eyed, and you could almost see the smoke coming out of his ears because he was thinking so hard. I've seen this look from Alice before: something so new it's mind-blowing and requires a loooong time to process.<br />
<br />
He tucked up a foot and I knew he had no intentions of leaving anytime soon. Bets were on that moderator rose would be the only one to stay long enough to see Patrick leave.<br />
<br />
I watched until 10 PM and then went to bed.<br />
<br />
I woke up early the next morning to the sound of owlet begging calls in the trees outside the bedroom window, and I got up quickly to see if Patrick had left. YES! So I quickly reviewed the video so see when he left. I watched at 64-speed as he sat there, got a snack, went back to his box, flew to the V-perch, went back to his box, and mostly did nothing. But at 5:13 AM he finally was ready, and flew slowly out the door to the big world outside.<br />
<br />
The owlets got an immediate lesson in Crows 101: they all got mobbed and chased and swore at by the resident murder of crows. (Yes, that's what you call a group of crows. A group of owls is a "parliament" which sounds much nicer.)<br />
<br />
At any rate, the owlets all settled in nearby and we'll track them daily to see where they're going.<br />
<br />

<br />
This morning at work I had the cams up and heard a noise that sounded suspiciously like an owlet hitting gravel. I saw one owlet missing from the perch, so quickly logged into the PTZ cam and waited an agonizing amount of time before I had video. I panned to where the other owlets were looking to find one of the girls on the ground with a rat that she had just caught. Right after I panned over she proceed to swallow the rat WHOLE! First time I've seen one of the owlets swallow something whole since they were 10 days old. <br />
<br />
She proceeded to look for another rat in hiding, and a few hours later caught another one. That one she tore into bits to eat, as usual.Karla (Kinstler) Bloemhttp://www.blogger.com/profile/13515204503379188869noreply@blogger.com7tag:blogger.com,1999:blog-9725321.post-69113393430331122982013-11-05T22:11:00.000-06:002013-11-06T07:25:25.039-06:00Putting on Transmitters<iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/nk5RMRPx75s" width="500"></iframe><br />
<br />
When it came time to put the tail-mounted transmitters on the owlets before their release, I really wanted someone with some experience to help put them on. I knew they were supposed to be sewn onto the central two tail feathers, but I figured a voice of experience could make the process go so much smoother. Thankfully Bob Anderson and Amy Ries of the <a href="http://www.raptorresource.org/" target="_blank">Raptor Resource Project </a>were willing to take a good chunk of time to lead this project, despite being busy with the Decorah Eagle Cam.<br />
<br />
Bob is a very thorough person. He brought along an extremely solid thread used to repair wetsuits that "you can tow a car" with, according to Bob. It simply won't break down. He asked for all kinds of materials from us: alcohol, a squirt bottle, epoxy, towels, needles, boxes, and more. He walked all four of us through how the process would go before we ever went out to get the first bird. We were ready.<br />
<br />
Catching the owlets wasn't too hard, although more difficult than their parents. The owlets didn't stay in the net when they flew in...they tried to get out right away, and all succeeded at least once. Patrick was the first to be caught and telemetered, if that's a verb.<br />
<br />
I carried him in, his feet were taped with painter's tape to make sure he didn't foot Amy, who would be doing "foot holding" duty. His head was covered with a towel, he was laid on his belly, and I gently restrained his wings and upper body while Amy held his feet.<br />
<br />
Bob separated the central two tail feathers and exposed the lower portions of their shafts. Hein sewed the thread through the four holes of the transmitter around the feather shafts, one piece of string wrapped several times around each shaft per hole. This was seriously a four person job.<br />
<br />
Bob put epoxy on each knot at the end, we let it dry, and then Patrick was put into a box until we finished with the girls.<br />
<br />
Each of the girls went through the same process. Bob was amazed at how well behaved they were compared to Peregrines. Patrick didn't struggle at all, and each of the girls only had one squirm session. <br />
<br />
When all of the owlets were outfitted with their new bling and we had recorded which owl had which frequency transmitter, we carried them all back to their flight pen. We saved Patience, the last of the bunch, the insult of going into a box...I simply carried her out with a towel on her head.<br />
<br />
We released them one by one and they all settled immediately onto their perches, ear tufts straight up to tell us they were not happy campers.<br />
<br />
We'll keep the owlets a few more days to make sure there are no issues with them wearing the transmitters. Then on Friday evening we'll open the door to the world and let them go. I expect they'll come back into the flight to mooch food for a while until they're confident on their own, so we'll probably still get glimpses of them. And there's also a chance we might finally get to see Rhett and Delilah on cam too.<br />
<br />
It'll be exciting and a great learning experience to see where they go and how far they stray...and if Victor hooks up with one of the girls. He's been single over a year, so he should be in the market....<br />
<br />

I have the radio telemetry equipment, but wanted to have someone with some experience put it on. I contacted a couple of experienced folks who would have been happy to help but were just simply too swamped. Thankfully Bob Anderson, although very busy himself, was willing to do it with Amy Reis on Monday or Tuesday. <br />
<br />
The transmitter itself will be mounted on the central two "deck" feathers of the tail. It will be sewn on to the feathers, and will fall off the owls when they molt those feathers next summer. So the trick is to then get the transmitters reattached to the birds so I can track them for a full year as the MN DNR requires.<br />
<br />
Here you can see the transmitter positioned on a dead owl (dead owls are great for practicing things like attaching transmitters).<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg_XX1tWlPb3ORAAfm78Rw1GxBzzI6nFcv9w-pbTEop4D2nMlJU3i5Qe0aXphCaXtAUnf1xEdh2U2KtsBUyRbg2eMGOFyrseA_hf3hZysp3W_cno1M5Co8yqOm1hoGqMZscEs2MfA/s1600/P1110044.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg_XX1tWlPb3ORAAfm78Rw1GxBzzI6nFcv9w-pbTEop4D2nMlJU3i5Qe0aXphCaXtAUnf1xEdh2U2KtsBUyRbg2eMGOFyrseA_hf3hZysp3W_cno1M5Co8yqOm1hoGqMZscEs2MfA/s400/P1110044.jpg" width="400" /></a></div>
<br />
<br />
These are not satellite transmitters, and I'll need to track the owls with a receiver, pictured below. Basically I tune it to the channel of each transmitter, move it around, and go in the direction that gives the loudest beeps. I hope the range on these transmitters and the good receiver I got will be able to handle the travels of the owlets.<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjm452_Br2kFOeUMb3uZ1CjaNQ6pLtiGXx7VfzHLcw0WpBfw-TOn7whwS7nTe2xy0zhf_UWQSu2cMsC-H7cDfyDZf4O_RkdL0S7us5h1iLeNn867nTBlEBFMFryEA4EHnGCI0oppA/s1600/P1110048.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjm452_Br2kFOeUMb3uZ1CjaNQ6pLtiGXx7VfzHLcw0WpBfw-TOn7whwS7nTe2xy0zhf_UWQSu2cMsC-H7cDfyDZf4O_RkdL0S7us5h1iLeNn867nTBlEBFMFryEA4EHnGCI0oppA/s400/P1110048.jpg" width="400" /></a></div>
<br />
Now before the transmitters are put on the owls we need to practice using the receiver to locate the transmitters, and involve the man who has agreed to help us track the owls. Kind of like playing hide-and-seek.<br />
<br />
Once the transmitters are attached to the owlets, we'll keep them a couple of more days to make sure everything is going well with owls and transmitters. Then we'll open the door to the big wide world and see what happens!Karla (Kinstler) Bloemhttp://www.blogger.com/profile/13515204503379188869noreply@blogger.com1tag:blogger.com,1999:blog-9725321.post-63542158736046522072013-11-01T07:38:00.000-05:002013-11-01T08:43:01.901-05:00From Baby to Teen to Adult Hoots!<iframe width="500" height="281" src="//www.youtube.com/embed/LstfkmoJjLE?rel=0" frameborder="0" allowfullscreen></iframe><br />
<br />
Patrick has finally gotten his hoot! The girls both were doing full-blown adult
territorial hoots before Patrick, but he has finally caught up with his sisters.
All owlets were doing "emphatic hoots" (hoots with extra notes in them that
indicated they are not happy campers) before they did their real territorial
hoots.<br />
<br />
Now that they have gotten their hoots and have practiced on rats,
they are ready to meet the world. I hope to get their transmitters put onto
their tail feathers this weekend, then give them a few days in their flight pen
to make sure everything is working well, then I'll open the door to the big,
wide world outside. And I'll be crossing my fingers that Victor takes a liking
to one of the girls so we have one that stays very close by.<br />
<br />
Once I've
opened the door to the wild, I'll still provide dead gopher in their flight pen
so they can come back and mooch until they are self-sufficient hunters. This is
called a "soft release" or a "soft hack."<br />
<br />
We'll be able to track the
owlets using VHF transmitters. This isn't like satellite transmitters (which are
very expensive) that just transmit locations that you can download every day.
These transmitters require human beings to go out with a receiver and pin down
the owls' locations by the beeping. Thankfully we have one person willing to
help us with this task. We need to track them for a year to see where they
settle and how they fare.<br />
<br />
I'll let you know as we pin down dates for
putting on the transmitters and for release, but it will be SOON!"EmmieJanhttp://www.blogger.com/profile/18129597402149719716noreply@blogger.com2tag:blogger.com,1999:blog-9725321.post-18857280127221334862013-10-11T20:05:00.000-05:002013-10-11T20:13:18.393-05:00Exam TimeRusty has been favoring his bad eye lately, holding it shut most of the time, shaking his head sometimes, and even sometimes rubbing his bad eye on his "shoulder." Also, sometime his poop has yellow urates. It was high time the boy got a checkup, and we decided to bring Iris also.<br />
<br />

<br />
Capturing them was easy. We have a big fish landing net with felt sown in in place of the netting. When they fly I simply extend the net up so they fly right into it. Easy squeasy.<br />
<br />
Iris rode quietly, but Rusty thumped around some. I think he wanted a bigger box.<br />
<br />
We took Rusty and Iris to Dr. Laura Johnson, nearly a two hour drive from here. (She's the one who took blood samples from the owlets for sex testing when we attempted to band them the first time.)<br />
<br />
Rusty went first, and the biggest concern was his bad eye. <br />

One look at it and Dr. Johnson knew it would have to be removed, a surgery she is not comfortable doing. The fluid inside the eye is increasing, causing pressure and discomfort.<br />

<br />
Iris' bad eye was the first thing to be looked at. The gray scar tissue on her cornea is the same as three years ago, so is fine. But she's developed scar tissue inside her eye from her original puncture wound that is pulling part of her iris (the yellow part) toward the back of her eye. Should be OK though.<br />
<br />

<br />
Iris had her eye pressure tested too, and it was low in her bad eye. It could keep decreasing and eventually her eye will shrink. We'll have to make sure that her body doesn't try to reject it at some point.<br />

Iris had to say "ahhh" too, and everything looked good.<br />

Dr. Johnson took a blood sample from Iris' leg, like she had done for Rusty too.<br />
<br />
So we'll wait for blood test results and then figure out the best place for Rusty to have his eye removed. Makes me appreciate how healthy Alice is!!<br />
<br />
I think Rusty and Iris are quite happy to be back home in their own space with no humans poking and prodding at them.Karla (Kinstler) Bloemhttp://www.blogger.com/profile/13515204503379188869noreply@blogger.com9tag:blogger.com,1999:blog-9725321.post-65822314094407890282013-09-29T10:21:00.002-05:002013-09-29T10:21:53.477-05:00Patrick's Amazing Rat Catch<iframe allowfullscreen="" frameborder="0" height="375" src="//www.youtube.com/embed/t1bunSbQFCs" width="500"></iframe><br />
<br />
The rats are winning again. Just when I thought we had everything sealed up so none of them could hide from the owlets, they got UNDER the baseboard for the walls. They still can't get out since there is wire mesh buried two feet down into the ground attached to the outside of the baseboard, but they can hide nicely from the owlets.<br />
<br />
I put out a pile of sunflower seeds to lure the rats out of their hole. It worked beautifully, but the clock in the owlets' stomachs said morning isn't the time to eat. So the owlets just sat and watched the rats. Argghhh!<br />
<br />
I happened to peek in and noticed an owlet hanging on the wire by the food tray. Then it bit at the wire. I thought it must have gotten stuck somehow and immediately started thinking about how fast I could get home to get it unstuck.<br />
<br />
Then I noticed a rat on the other side of the wire, in the owlet's talons! The owlet was trying to grab the rat with its beak to pull it through. Eventually it succeeded! <br />
<br />
When I got home I reviewed the video and found that it was our amazing Patrick that made the catch. Why he went for such a hard catch while totally ignoring the rats on the floor in front of him is beyond me. Maybe he just wanted to show off to his sisters.Karla (Kinstler) Bloemhttp://www.blogger.com/profile/13515204503379188869noreply@blogger.com2tag:blogger.com,1999:blog-9725321.post-36409954243104808442013-09-18T19:14:00.003-05:002013-09-18T19:14:28.587-05:00Website compromisedThe International Owl Center website has been compromised, so we are working with our web host to deal with the issue and establish new security protocols.

The owlets are still working on their hoots and their rat catching abilities. Early this morning Victor, the neighbor wild male (single I might add) was over hooting in the yard. In this clip you can hear him land on the aviary roof (the owlets jump a bit.) Rusty is hooting back at him, but when one or the owlets interrupts him with a teenager hoot, Victor appears to freak and bolt. You can then hear him hooting in the distance. I wonder if he had no idea what that squeaky thing was...."EmmieJanhttp://www.blogger.com/profile/18129597402149719716noreply@blogger.com1tag:blogger.com,1999:blog-9725321.post-83718819883078292272013-09-05T10:39:00.002-05:002013-09-05T10:44:28.480-05:00Two Note Hoot<iframe allowfullscreen="" frameborder="0" height="375" src="//www.youtube.com/embed/9uDC3p_V8ts" width="500"></iframe>
One of the owlets did a two-note hoot last night, IN AN ADULT VOICE! This two-note hoot is usually more of a greeting, so the context seems odd with the annoyed chitters, but it is a real adult voice! The juveniles are maturing!<br />
<br />
When all three are using their adult voices to hoot they can be released to the wild.

<br />
We're back to using the medium-sized rats again. The owlets were doing pretty well at first, then just slacked off and stopped trying very hard to catch the rats. Maybe it was the heat, since exerting lots of energy when you're hot isn't so fun, plus they don't eat as much when they're hot. But for whatever reason, I went in two mornings to retrieve rats that were still running around in the pen so they didn't start digging under steel and getting into the walls again.<br />
<br />
But I was too late. A gray one was already in the wall and has now been seen on the food tray drinking out of the water bowl. And I watched on video while a white one climbed up the steel in a corner and got up into the wall through the chain link. Sigh.<br />
<br />
Last night I only gave them one piece of gopher and three rats. They didn't catch any of the rats. No one looks like they're starving. So I'll go ahead for a while and offer very little food so they get motivated to learn how to catch rats better. This is what their parents would naturally do...withhold food to get them motivated to hunt.<br />
<br />
Hunting is a natural instinct and just requires practice (which takes motivation.) So here's to motivating the juveniles to hone their hunting skills!Karla (Kinstler) Bloemhttp://www.blogger.com/profile/13515204503379188869noreply@blogger.com0tag:blogger.com,1999:blog-9725321.post-48099967361865969332013-08-19T12:09:00.001-05:002013-08-19T12:20:35.873-05:00Rusty takes a Sand Bath<iframe width="500" height="375" src="//www.youtube.com/embed/aralEmmWFBc" frameborder="0" allowfullscreen></iframe>
I only knew owls took water baths until one day several years ago I saw Iris thrashing around on the floor of her pen. I thought she was having a seizure, but realized she was trying to take a dust bath. So we added a pan filled with sand, and occasionally the owls now take sand baths.
I think this is the best video we have of a sand/dust bath, since Rusty was nice enough to do it during daylight hours for us. Why do they do this? Good question. Perhaps it can help control ectoparasites like lice and flat flies. Or maybe it just feels good. No idea.EmmieJanhttp://www.blogger.com/profile/18129597402149719716noreply@blogger.com0tag:blogger.com,1999:blog-9725321.post-32265130304557658902013-08-19T12:03:00.002-05:002013-08-19T12:05:13.816-05:00Chirps...? <iframe allowfullscreen="" frameborder="0" height="375" src="//www.youtube.com/embed/LaUk5xhQaso" width="500"></iframe>
Great Horned Owls make all kinds of sounds we don't expect. Yes, they sneeze. They also make a soft, short squeaky sound when they stretch a wing and leg sometimes. But chat room moderator rose noticed a different kind of sound: a short "chirp" that is given just as an owlet starts to fly.
I'm not sure if its only one owlet doing this, but I don't think its all of them since otherwise I think we'd hear it a lot. But some nights when she's doing her late shift of observations she notices it several times. What does it mean? I have absolutely no idea. I'm certain this sound has never been recorded or described before, so let's watch to see if it's only one owlet, all the owlets, if it's always given when they start flying, or any other details of what's going on.
Thanks rose for catching this so many times!EmmieJanhttp://www.blogger.com/profile/18129597402149719716noreply@blogger.com4tag:blogger.com,1999:blog-9725321.post-66729980697819822922013-08-18T15:09:00.002-05:002013-08-18T15:10:53.702-05:00Owlet Chittering and Hooting in Its Sleep<iframe allowfullscreen="" frameborder="0" height="375" src="//www.youtube.com/embed/zDLx36NW-3E" width="500"></iframe><br />
<br />
I've always known that owls can talk in their sleep since I've seen and heard Alice do it many times. But I never had a recorder or video camera handy, and it happens way too fast anyway.<br />
<br />
Thanks to dedicated cam viewers, we're finding out new things about owl vocalizations. Jonnetje from The Netherlands was online in the wee hours of our morning (daytime for her) and she noted an odd vocalization. I went back to the place in the video she indicated and found this clip.<br />
<br />
The owlet on the right is sleeping, but with the sound up you'll hear quiet chitters, but they are annoyed. (Obviously no one is doing anything to annoy the owlet.) Shortly after is a mumbled, muffled, high-pitched hoot. A "sleep hoot" is muffled and mumbled anyway since the gular sac can't expand when their head is settled down while sleeping, but this owlet sounds extra odd because it's vocal apparatus is not developed enough to give a low adult-type hoot.<br />
<br />
Notice that the owlet woke itself up with its hoot. Alice does this sometimes too.<br />
<br />
Thanks to all of you who are watching and submitting your observations!Karla (Kinstler) Bloemhttp://www.blogger.com/profile/13515204503379188869noreply@blogger.com2tag:blogger.com,1999:blog-9725321.post-61145569353995719482013-08-13T08:10:00.001-05:002013-08-18T15:11:09.693-05:00Teenager Hoots<iframe allowfullscreen="" frameborder="0" height="375" src="//www.youtube.com/embed/uFQ1EZxCX1A" width="500"></iframe><br />
<br />
This is another MOMENTOUS occasion: one of the owlets started doing big kid hoots this morning at 3:57 AM!<br />
<br />
One of the things I'm working to document is the development of the territorial hoot in young owls. We recorded the tiny little peeping hoots they did when just over two weeks old. Those only seemed to last until four weeks or so, and then nothing has been heard since.<br />
<br />
Yesterday we separated the juvenile owls from the adult owls. It was simply the time of year to do it, and the kids weren't roosting by their parents so much anymore. I figured the owlets wouldn't start hooting as long as Mom and Dad were around to defend their territory.<br />
<br />
Last night Rhett and Delilah, the resident wild owls, were in the yard hooting for a few hours. After a couple of hours of hooting, one of the owlets flew to the V-perch and started hooting!! The hoots aren't as quiet and peepy as the nestling hoots...they're squeakier more like a rubber ducky trying to hoot. But a hoot it is, with proper hooting posture (throat pouch inflated, leaning forward, tail cocked up.)<br />
<br />
Based on the video and the rhythm, I am suspecting it's one of the girls doing the hoot...maybe Pandora, the oldest?<br />
<br />
I'll be anxious to hear when the others start hooting, what they sound like, and how long it takes to make a real adult-sounding hoot.<br />
<br />
Woo-hoo!!!Karla (Kinstler) Bloemhttp://www.blogger.com/profile/13515204503379188869noreply@blogger.com7
