Re: [cobirds] Re: Mexican Duck marina at Cherry Creek SP (Arapahoe county(

[Gary Brower]

All,

Several questions, then, for those who know about (or consider) these things . 
. . .

1)  Was Mexican Duck made a separate species in the last go-around? I can’t 
remember.  If so, then it’s Life Bird for me — I’ll head to CCSP tomorrow.
2)  If it’s a Mottled Duck, it’s a Life Bird for me — I’ll head to CCSP 
tomorrow.
3)  If it’s a Mottled x Mexican hybrid . . . . how does one “count” that?

Thanks!

Re: [cobirds] Re: Mexican Duck marina at Cherry Creek SP (Arapahoe county(

[Scott Somershoe]

All,
Sorry for not posting sooner. Birding happened today. 

Anyway, this bird on first blush looks like a Mottled Duck to a bunch of us. 
However the broad white line on the leading edge and trailing edge of the 
speculum eliminates Mottled. It also doesn’t totally match Mexican duck (not 
that I’ve seen one to my knowledge).  I managed to study the bird for a while 
this morning and Ben’s photos are great! Way better than mine. I did see a 
couple random green feathers at the base of the tail as well. Weird. 

According to waterfowl guru Steve Mlodinow, he thinks it may be a mottled x 
Mexican hybrid. I’ll leave a final decision to those smarter than me! Really 
interesting bird regardless. As I say, there’s always more to learn.

[cobirds] Colorado Rare Bird Alert - Tuesday, January 15, 2019

['Allison Hilf' via Colorado Birds]

Date: January 15, 2019
Compiler:  Allison Hilf, ah...@me.com
E-mail:  RBA  AT cobirds.org
 
This is the Colorado Rare Bird Alert for Tuesday, January 15, sponsored by 
Denver Field Ornithologists. 
 
Rare, out of place and out of season species include:  
(*) indicates new information on this species;
CAPITAL LETTERS are used for very rare species, as listed by the Colorado Bird 
Records Committee.
 
Barnacle Goose/Pink-Footed Goose - Weld County
Note, both birds are extremely rare vagrants to Eastern North America; almost 
unheard of in Western North America.  Pink-footed Goose is very rare in 
captivity; whereas Barnacle Goose is somewhat common in private 
agriculturalists collections.  

Populations of both of these geese are increasing in their breeding habitat, 
with about twice as many Barnacle than Pink-footed Goose. Both birds are also 
expanding north over the top of Greenland and could end up in NE Canada, 
putting them close to Goose populations that winter in the Great Plains.  Steve 
Mlodinow posted a thorough summary on previous sightings and detailed rationale 
for the Colorado Bird Records Committee to ponder.  Paul Hurtado also suggested 
the following pdf from ABA Birding Magazine about Greenland Geese:
http://publications.aba.org/birding_archive_files/v40n3p46.pdf

There is no guarantee either of these is a wild bird and/or that either will be 
accepted by the CBRC; but this might be your only chance to see them in CO.

Both birds were last reported yesterday (Dec 14) at Frederick Lake (Milavec 
Reservoir) & Recreation Area in Frederick.  The Pink-footed was reported until 
noon; the Barnacle was reported as late as 5pm.  

Observers have been diligent in reporting sightings on CObirds; please keep 
reporting all sightings on CObirds and check for any location updates.
