I live in suburban Denver, CO and have 5 kestrel chicks that are 3,4 and 5 days old respectively. There is a nearby raptor research and rehabilitation group that has offered to come band the chicks when they are two weeks old. I'm intrigued about doing this, but am also worried about stressing out the chicks and the parents and want to weigh the pros and cons. Do any of you have experience with banding your chicks and do you have any advice? I only want to do it if there is a clear scientific benefit for doing it--don't want to do it just for the "gee whiz" factor. Thoughts?
