Whoops, I screwed up (again) & should have read the final rather
than the proposed changes:
But this brings up another question I have. Does anyone know
where the discussions on each proposal
can be found? I'm especially interested in the decision NOT to
resplit Yellow-rumped Warbler.
As I understand it, the two forms interbreed in a contact zone in
British Columbia. What about
the rampant interbreeding of Hermit and Townsend's Warblers
recently described by Dave Irons
(see
https://mail.google.com/mail/u/1/#search/townsend%27s/15d108f1a9577237)
For consistency shouldn't they be lumped?

Here are the Proposals considered but not accepted by the
committee as they impact US birds recognition of Eugenes
viridiceps as a species distinct from the newly circumscribed E.

Certhia albescens as a species distinct from C. Americana (Brown
Creeper), Junco alticola as a species distinct from J. phaeo notus
(Yellow-eyed Junco), Oreothlypis ridgwayi as a species distinct
from O. ruficapilla (Nashville Warbler), And S. auduboni and S.
goldmani as species distinct from S. coronata(Yellow-rumped
Warbler); merger of Junco hyemalis (Dark-eyed Junco) with J.
phaeonotus , and merger of Acanthis flammea (Common Redpoll) with

Hi -
My just-completed reading of the new Checklist supplement
indicates that the Committee declined the petition to change
this name.

first edition of his Field Guide to the Birds (1934) Roger Tory
Peterson states under the Ring-necked Duck heading

"The name Ring-billed Duck would be more appropriate, as an
examination at very close range is necessary
to be aware of the dull chestnut ring that encircles the neck."

I doubt he was the first to mention this.

Whenever I pointed out this duck to casual birding friend s or
acquaintances I would always mention this
bit of avian trivia. I really enjoyed that. But no more. Many
decades later the AOU has done the deed.
I'm going to miss the Ring-necked Duck sorely.

See attached photo. The Oregon Zoo allows RTP's very close
examination. I imagine hunters also had/have
the occasion for such an examination.
