Night Voices: Great Horned Owls 

Written by Bob Sundstrom

This is BirdNote.

[Crickets-nighttime + call of female Great Horned Owl] 

After dark, it’s our ears that connect us to the lives of birds. And one of our most familiar connections is with the lovely and mysterious hooting of Great Horned Owls. [call of male Great Horned Owl] 

When a pair of Great Horned Owls calls in a duet, the female usually hoots first [female hooting], and the male replies at a lower pitch [male hooting]. Even though females average a third larger than males, the smaller male has a bigger voice box, or syrinx. Here’s the female again [female hooting].  Now the male [male hooting].

Great Horned Owls may also pierce the darkness with an eerie shriek [shriek of juvenile], which may signal a hungry owlet begging for food or a female defending its nest [shriek]. Adult owls also bark in response to threats [“bark” call]. 

In fact, Great Horned Owls have a lot to say. Female owls sometimes call out with high-pitched trills [female “chitter” call] or hearty squawks [squawk], and Great Horned Owls hiss, pop, meow, coo, and snap their bills [bill snapping].

So have a listen after dark. There may be a Great Horned Owl in your neighborhood. [Great Horned Owl duet] Today’s show brought to you by The Bobolink Foundation.  For BirdNote, I’m Michael Stein.
