American Crow

Early in the morning when I look around outside, often I can spot one or two crows on top of a tall tree.   They are said to be one of the smartest of all the birds.  

Often I see them acting as goodwill police by spotting a hawk, giving a warning call loud and clear, and chasing the predator out of the way. 

Per National Geographic's Field Guide, adults are readily identified by familiar CAW call whereas juveniles give a higher-pitched, nasal CAH begging call. 

Last year a few crows came down to my backyard to wander around.    A male, a female, and a juvenile all look alike: All-black bird with black bill, legs, and feet.  They eat fruit, insects, mammals, fish, seed, and the suet.  Some can live up to 20 years.

So next time when you hear a crow, just listen.  Is it an adult or a juvenile?
