Took these snapshots in my backyard yesterday - this bird was watching me like a hawk!
Recently a paper was published in The Southwestern Naturalist discussing red-tails, such as this one, hunting down and feeding on American kestrels and barn owls!
I wonder what could be motivating these guys to take on such high risk prey items?
