I copied this from a post by Phil Davis on Bird-Chat and I thought many of 
you would be interested in the following. It has been something expected for a 
long time. I really like armchair list additions as ABA follows the AOU. It 
pays to keep good notes and photos on subspecies;o)
Good Birding!!!

The 45th Supplement to the AOU Checklist is now out. It was published in
the July 2004 issue of the Auk 121(3):985-995. 

Cackling Goose has been split and is now a separate species from Canada
Goose:

a. Cackling Goose (Anser hutchinsii) [the small forms] includes the former
Canada Goose subspecies hutchinsii [Richarson's], asiatica
[Bering-extinct?], leucopareia [Aleutian], taverneri [part of the Lesser
complex], and minima.

b. Canada Goose (Anser canadensis) now includes the subspecies canadensis
[Atlantic], interior [Interior], maxima [Giant], moffitti [Moffit's],
parvipes [the other part of the Lesser complex], fulva [Vancouver], and
occidentalis [Dusky].

The Checklist committee telegraphs that more splits of this complex may be
yet to come. [The separation of the Lesser complex may present a field
challenge.] For a good treatment of Canada Goose subspecies (prior to the
release of this supplement), check Angus Wilson's web site at ...
