Is it a Common or Chihuahuan Raven?

[Robert Righter]

Hi

In the recent North American Birds, Vol 75, Number 1, ’24 there is an excellent article by David Sibley about the conundrum of how to separate (or not) the Common Raven from the Chihuahuan Raven. The article is informative as it shows how  Sibley, using methods of field ornithology, slowly untangles  the complexities of raven identification. In Colorado sighting of the Chihuahuan Raven may actually be rarer than what we all thought. Nathen Pieplow and Tony Leukering were cited in the article for their contributions. Read the article and share your thoughts.
