Looking Good for Breeding!



Rusty and Iris have lived in their aviary in Houston, Minnesota for a year now. They didn't breed the first year most likely because they were still getting settled into their new home and because a wild, unmated female named Scarlett Owl Hara harassed them every day throughout breeding season and even continued into June, August, and September!

But things are looking good for Rusty and Iris to breed this coming season. Firstly, Iris has been joining in with Rusty in his hooting bouts. Rusty is an enthusiastic hooter, hooting many, many times a day. Iris never really said much, which may have been part of the reason Scarlett was so intent on trying to get Rusty for her mate. But now I'm happy to report that Iris often hoots with Rusty, as you see in this video.

Iris is also spending her nights roosting by the nest...another good sign that she's starting to think about nesting. She and Rusty both cache their leftover food in the nest too.

But the most exciting thing for me is that it appears Scarlett has finally found herself a man!! There's a pair of owls that have been hooting about half a mile west of here for a few weeks now. Scarlett has a pretty distintive hoot, and the female of that pair sounds for all the world like Scarlett. And when those owls are hooting, I don't hear Scarlett in the yard. Perhaps this has bolstered Iris' hooting confidence....

At any rate, I'm very hopefully that we'll have nesting this coming season. The Cornell Lab of Ornithology's Nest Cam project will again be hosting Rusty and Iris, but this year on Ustream...commercial free! Keep watching for the new link. But for now you can still watch Rusty and Iris on Ustream at http://www.ustream.tv/channel/great-horned-owl-breeding-project.

  1. Gosh it doesn't seem possible that it has been almost a year, but yes, it is November, and I know owls pair up in January/February. I hope their efforts are successful. If they do breed what eventually will happen with the offspring? Will they be hacked in some way that allows the parents to continue to feed them until they learn the ropes?

  2. When they have kids I'll let the kids move into the release training cage in the fall when they would normally disperse from their parents. They'll stay in that cage, building up their flight muscles, until they develop their full territorial hoots, then will be soft-hacked to the wild from their cage after being trained on live prey.

  7. The picture is me with Alice, my human-imprinted education bird. We were outside for a photo shoot and it was cold, so I was kinda trying to tuck her partially under my jacket.
