Somewhat related to me is the difference in vocalization between American
Crows here in the great Northwest and American Crows on the East Coast. I
lived in Maryland and never heard an American Crow make the meowing cat
call sound there! Are we talking subspecies here? Of course I never heard
of anybody suggesting to lump Fish Crow with American Crow either!

The American Ornithological Society (AOS) has released the new proposals

for splitting and lumping that it is considering. They are here:

Most concern splits of extralimital subspecies in the tropics (the AOS

However, the first proposal on the list is to re-merge Northwestern Crow

They were split last year based on research presented in Slager et al

It's a bit mind-numbing reading, but that's the scientific process at work.
