Are crows monogamous?

I regularly peruse crow photographs on flickr. Today I found this one. What an excellent photograph, don’t you think? Under the photograph the question was asked, “Are crows monogamous?” Are crows monogamous? Are ravens monogamous? I thought this would be a good post for today.

Yes, crows and ravens are monogamous. They generally mate for life. They are social birds. John M. Marzluff and Tony Angell stated the following about crows in their book In the Company of Crows and Ravens,

“Crows and ravens care for each other, spend years living at home, engage in foreplay, and mate for life but now and then mate with others. Large groups cooperate to sleep in safety, drive away mutual enemies, and maybe even dole out justice.”

Interesting, eh? We could learn a thing or two from crows and ravens. Maybe being close with family and friends is not just for the birds…

Thanks to mikE~510 for the photograph, the question and the inspiration to write this post!

Crows Can Recognize The Calls Of Relatives

ScienceDaily (2007-03-20) — Most of us would know our mother’s voice on the phone from the first syllable uttered. A recent Cornell study suggests that crows also can recognize the voices of their relatives.

This woman did a lot of in-depth research for this study. I am not surprised in the least to find out that crows recognize each others voices. We do. We are so egocentric sometimes!

Tiny Crow Camera Spies On Clever Birds

ScienceDaily (2007-10-10) — Researchers can now ‘hitch a ride’ with wild birds and witness their natural and undisturbed behaviour. Scientists developed miniaturised video cameras with integrated radio-tags that can be carried by wild, free-flying birds. Using this new ‘video-tracking’ technology, they spied on the behaviour of New Caledonian crows, a species renowned for its sophisticated use of tools, recording behaviours never seen before.

This is very interesting. I would love to watch some of these videos to see where the crows we feed go off to in between feedings. They are such clever birds, aren’t they?
