I get a lot of different birds of prey coming through each year. I've got a sharp-shinned hawk keeping an eye over the chickens as of late. But one of my favorites to watch through the summer are the kingfishers that setup shop in my backyard. They are damn good at catching minnows! Great blue herons are also fun to watch stalking frogs and minnows in the shallows of the pond, but I have to be a bit stealthier to watch them as they'll flee once they see me.
I heard owls out back for the first time since spring just a couple nights ago, I usually get one or two horned owls that setup shop here for a few months in the late fall and again in early spring. They are hell on the bunnies and you won't soon forget the sound of a bunny dying at the beak of an owl.
