G’day all
Twitter just severd this article up:
Jønsson, K A, Fabre, P-H and Irestedt, M. 2012. Brains, tools, innovation and biogeography in crows and ravens. BMC Evolutionary Biology 12: (72)
http://www.birdwatch.co.uk/categories/articleitem.asp?item=918
Apparently the eastern and western populations are genetically distinct and separated by a 100km wide C. coronoides gap along the Great Australian Bight. The geographically well-separated populations of the Forest Raven, on the other hand, are not distinct.
Apologies if this is old news to most of the group!
