The other day in the evening I was laying on my hammock reading some magazines when I look up and a Kestrel or some other kind of bird of prey is trying to get another bird, BUT its being dive bombed by to other birds the same size! Unbelievable! Judging by the sound of their calls, I thought they were robins! But they also could've been Blue Jays. Looks like I have my hawk problem figured out. I have my own Air Force now
