Those guys rock! I see them sitting on the power lines along rural roads. I heard they can take out doves!
Mourning doves can do 70 mph in powered flight. A kestrel can overtake and catch them. But doves at not a common prey due to their size.
Lee Slikkers, another of our members here on P.A. has flown kestrels on starlings and English house sparrows since they are not protected species.
Didja know mice leave trails of urine EVERYWHERE they go? And their urine glows bright blue under a black light. If your kids have a pet mouse or rat, go CSI: Mouse-ami with a blacklight in their room and check it out. Kestrel eyesight processes in the Ultraviolet range...they are known to follow mouse trails to find the mouse at the end of the rainbow.
