Corvidae: Crows, Ravens and Magpies Quick Facts

November 18, 2009

I have compiled information regarding the American Crow, Common Raven, and the Common or Black-Billed Magpie in this table.  Please feel free to contact me if you have any questions.

In addition, below the table is a great website with audio corvidae vocalizations.

Enjoy!!!

BTW:  Please excuse the table formatting – this is my first wordpress.com table.  Which means the tables will hopefully get better!
