Our rehabber deliveredd Primo to The Birds of Prey Foundation in Broomfield (about seventeen miles northwest of Denver) yesterday.
He was released on the ground and immediately flew to near the top of the cage with no problems, that is a very good indication. He will also be offered 'live' prey to help him learn to chase, catch and kill his own food.
Bob told me on the phone today that our rehabber will try to get some photos to share of the flight cage and Primo. I will post as soon as I have them. Here is a link to the foundation's flight cage virtual tour http://www.birds-of-prey.org/Tours/TourCages/tourcages.html
