We have always had them here,. we call them split Tailed kites,..with no problems,.. but I just had a pair in the yard swooping only 15-20 feet over my head and they took no notice of my running and hollering and waving at them. It's 90 degrees out there so all the young ones are under cover but some of the hens were out,.. DD thinks maybe it saw the black water hose and thought it was a snake,. their favorite meal,.. and she may be correct,. but has anyone ever had one take a chicken?
