Fred, thanks for sending me the article. I just read it and it gave me some motivation. Have any forum members used this method on a Peregrine falcon and will it work equally as well with a Peregrine? Bill I know you have hacked Peregrines is this a method you would use or if not what do you do. I'm particularly interested because I am thinking of taking a female Peregrine this year at about 27 days old.
