Crows are common in the city but ravens are rare so I was surprised to hear a raven this week in Schenley Park. It called and circled overhead waiting for its companion to arrive. “Brrrock! Brrrock!” When the second raven caught up they flew away together.
I see ravens in town about twice a year but I only hear them make the Brrrock call. If I lived where common ravens (Corvus corax) are common, I’d hear their wide variety of sounds.
This video from Anchorage, Alaska gives you an idea of the ravens’ vocal range. He starts with Brrrock. Then he gets creative.
