Taxonomy of the Northwestern Crow Corvus caurinus

 

Currently there is a proposal to The North American Classification Committee to consider re-splitting Northwestern Crow from American Crow. This proposal has garnered interest in a recent article by Robert W. Butler, published in British Columbia Birds, so we have decided to make the article generally available rather than having it confined to the Members Only pages of the British Columbia Birds website. You can download the paper here.
