It's well past the season for it, but the screeches of along-eared owl are unmistakable in the spring.
In my years of Catskill weekends on an isolated property, it was not at all unusual to hear the sounds of the seasonal nighttime fauna waking up (we tended to eat late)while I was out tending the meat on the grill.
Packs of coyotes yipping, Grat Horned Owls hootig back and forth . . .
One sound that stood my hair on end was the rising call of a long-eared owl, perhaps as it encountered another. The only way know to describe it is as of a rising crescendo to the point that it sounded like a cat or raccoon fight, without the growls at the end of it.
Don't discount them as a threat. Seemingly large bodied owls, like the Long-Eared and the Great Horned, if you were to dress one out, wouldn't be as big as a scrawny chicken. Most of their apparent size is feathers. But they have deadly talons, and wings that will lift far more than their own weight.
