Subject: AOU Checklist 45th Supplement Summary
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. For those not
familiar with the AOU Checklist, it governs taxonomy (including
splits/lumps, common names, scientific names, and order) of North
American species. Note that the ABA Checklist is what governs the
publication of the ABA listers totals; the ABA typically issues their
own report subsequent to the release of AOU supplements.
Highlights (pertaining only to north of the Mexico border):
1. The species Great-winged Petrel has been added to the checklist,
based on west coast pelagic records.
2. 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 ...

3. The common name Mongolian Plover is now Lesser Sand-plover, to agree
with modern Old World literature.
4. Greater Sand-plover is added to the main checklist, based on the
record from California.
5. The common name Spoonbill Sandpiper has been changed to Spoon-billed
Sandpiper.
6. The common name Jungle Nightjar has been changed to Gray Nightjar to
agree with modern Old World literature.
7. Willow Warbler has been moved from the Appendix and added to the
main checklist, based on the record from Gambell, AK.
8. Lesser Whitethroat is added to the checklist, based on the record
from Gambell, AK.
9. The common name of Siberian Flycatcher has been changed to Dark-
sided Flycatcher to agree with modern Old World literature.
10. The common name of Gray-spotted Flycatcher has been changed to
Gray-streaked Flycatcher to agree with modern Old World literature.
11. Spotted Flycatcher has been added to the checklist base on the
record from Gambell, AK.
12. The western Alaska subspecies of Yellow Wagtail has been split from
the Yellow Wagtail complex and now appears on the checklist as the
Eastern Yellow Wagtail (Motacilla tschutschensis). (This is the only
"yellow" wagtail on the AOU checklist.)
13. Rufous-tailed Robin has been added to the appendix (not the main
checklist) based on a record from Attu.
14. Blue Rock Thrush has been added to the appendix (not the main
checklist) based on a record from British Columbia.
15. There are numerous changes to scientific names.
