There are many species of owls in the Adirondacks, with barred owls being the most common, and the most frequently seen.
We mainly hear owls calling between Autumn and early Spring. Great Horned Owls nest earlier than other owls, and their deep staccato HOO-hoo-hoo-hoo-hoo-HOO call, sounding most like the stereotyped call we associate with owls generally, is resonant and vaguely threatening.
The Long-eared owl, which resembles a smaller, perpetually startled and skinny great horned, has a call which reminds you more of song bird calls, stretched out with longer pauses between notes, which may be single syllable “ooo” or raspier pleas, sounding almost cat like. Screech owl calls are shrill and loud, sharp and abrupt. If you ever watched the comedy “My Cousin Vinny”, there is a funny scene where the Joe Pesci character, surprised by a screech owl’s scream in the dead of night, runs out of the cabin firing a pistol, followed by a close up of the screech owl. Tiny saw whet owls make a “toot-toot” call, like a small truck backing up.
