If Chance does perch and looses her balance, can she glide safely to the ground with the amount of feathers she has now. How much more of the down does she need to loose. Yesterday morning, it looked like she was getting a little altitude in the box when she was exercising her wings. The worst part of watching these peregrines for me is when they leave the box. Waiting to know if they have been spotted on the ground and are OK. At least this year, the flies don't seem to be a factor and she won't have to jump to get away from them.
