you have to remember the falcons are training their youngsters so there will be as much as 5 or 6 in the sky at one time . i watched with my own eyes one night last week . if our birds are on line of flight with these bops you will have birds missing or hurt . I ve lost 5 to date . couple of cheq pieds and three blues.. color means nothing i think it depends how high the birds are when the attack is happening if your birds can t get to ground quick enough its a gonner
