I had a Great Horned Owl in my yard last year, and I was tipped off by about 15 magpies squawking and swooping at a spruce tree. I've only seen a Long-eared Owl once, and it was being mobbed by crows. Last year a mob that included ravens, magpies, Blue Jays, and even two Hairy Woodpeckers led me to a Northern Goshawk. And recently I saw a mob of magpies, crows, Blue Jays and starlings chase a Merlin carrying a dead starling out of tree across the street from my house. In all these cases I never would have seen the bird of prey if it weren't being mobbed. The “corvid alarm” is a great way to find birds of prey.

He has an intense stare. I wonder what he's thinking.... I love the shot of him looking down at you. He has an intense stare. I wonder what he’s thinking….
