It would appear so. I have a check list from the San Pedro river in AZ, it
shows Mexican Duck. However, my life list number has not changed ..yet!

Hi folks,
The AOS has a committee called the NACC as described by Mark, and that
committee makes taxonomic decisions on changes to the official AOS
checklist on a regular basis (biannually, I believe). For the purposes of
discussion, the AOS and the NACC are functionally the same, as the NACC is

All,
See the ABA blog for more on lumps and splits from the American Ornithological
Society’s Committee on Classification and Nomenclature of North and Middle
American Birds (whew).

The NACC accepts all of ABA’s changes, but the AOU goes its o
The confusing part is, that the AOU checklist committee didn't accept
Mexican Duck as a full species (as far as I can tell). The ABA Checklist
committee always follows AOU on split species. So, I'm thinking that
Mexican Duck doesn't count any lists submitted to ABA Listing Central (is

Hi Everyone,
The 2018 ebird checklist went live today, as did the Clements checklist. Here
is the change comment.
The monotypic group Mallard (Mexican) Anas platyrhynchos diazi is elevated to
species rank as Mexican Duck Anas diazi. Genetic divergence of Mexican Duck
from Mallard is at c
Did Mexican Duck get split from Mallard?? E-bird seems to think so, so I
was wondering, if anyone knows for sure, it is all confusing to me. If it
has, then this will be a new species for Colorado, since there have been
more and more Mexican Ducks in the state, in the last several years.

There is no Black-eared species, though black auriculars are more prevalent in
subspecies in Mexico than in the United States. It’s worth the small
subscription fee to have access to Birds of North America (BNA) Online. It
tends to be the most current authoritative source for understanding curre
So basically it sounds like the few Black-eareds we have this far north are
immature males. Would that suggest some Black-eared genes?

A small piece of the Black-eared Bushtit puzzle was discovered by one of my New
Mexico birding mentors, Barbara McKnight. The long-time secretary of the New
Mexico Ornithological Society, Barbara had a banding project in the Sandia
Mountains. Sometime in the late 1960s or early ‘70s on her bandi
In the November 12, 2015 edition of "Birdwatching Magazine" Kenn Kaufman

considered
a separate species, but are now known to be variations of the Common
Bushtit.
They were two species until 1931, when they were lumped, then spli
