HI:
From the AOS: The latest supplement to AOS's Checklist of North and
Middle American Birds, published today in The Auk: Ornithological
Advances, includes several major updates to the organization of the
continent's bird species, including the addition of the Mexican Duck and
the removal of the Northwestern Crow.

A lump nearly 60 years in the making!
