Re: [cobirds] Purple vs. Cassin's Finches--Purple Finch in El Paso 10/25, 26, 27

[macawolf via Colorado Birds]

Yes, Duane Nelson, thanks for that pic and your description. 
I have no photos, but based on this thread and Duane's description, I'm now 
convinced that what I had identified as a female Cassin's Finch on 10/25-27 in 
our back yard was actually a Purple. Present 3 days but only for very brief 
visits--it seemed extra skittish. I originally identified it 10/25 (and posted 
to ebird that day and again the 26th) as a female Cassin's; I edited those 
reports tonight, because I do remember thinking on the 25th that it must be a 
partially leucistic Cassin's due to unexpectedly greater & distinctive white 
(in eyebrow & malar) surrounding the brown cheeks. 
I didn't even think of Purple, not being too familiar with them. Was not able 
to get photos. Seeing the thread about Purple Finches (vs Cassin's) on COBirds 
today made me reconsider--especially Duane's contribution, with his photo.

What a FANTASTIC comparison picture! Thanks for sharing!
I saw the female Purple today in Broomfield. What a treat; used to see them all 
the time when I lived in Western WA.

[cobirds] Re: "Small gull with M pattern"

[willc...@gmail.com]

Hi All,

I think the description of a dark M on the back for a juvenile Sabine's 
gull makes perfect sense, and is both helpful and descriptive for newer 
birders. It is a common term when used in relation to Sabine's Gulls in 
juvenile plumage, and I see no need for a change of the lexicon.

thanks,

Will

Re: [cobirds] "Small gull with M pattern"

Also yet the Sibley app states "pied wing pattern resembles dark M of other
species" in description of Juvenile Sabine's Gull, but let us note that the
juvenile wing pattern is the same as the adult wing pattern.

[cobirds] Red-necked Grebe, Adams County

[Adam Vesely]

Hi all,

I had a Red-necked Grebe this evening in Brighton (Adams County). 
Specifically, the bird was in this unnamed reservoir: 
39.951870, -104.853188 which can be accessed by parking here: 
39.943753, -104.852972

A little further north there were 3 Common Loons in "Cell No. 3" Reservoir.

Yet, the Cornell app “Merlin” uses the convenient descriptor "Small gull with 
distinctive bold "M" pattern on wings in flight, formed by black outer 
primaries, white inner flight feathers, and dark back,” in its description of 
Sabine’s Gull.

[cobirds] "Small gull with M pattern"

[coloradodipper via Colorado Birds]

All:
The number of species of "small gulls with an M pattern" that are possible in 
Colorado is five: Ross's, Little, Bonaparte's, and Black-headed gulls and 
Black-legged Kittiwake. The "M pattern" refers to the "M" described by the dark 
primaries and the stripe of dark crossing the otherwise pale coverts to the 
wrist from the base of the wing.
Sabine's Gull does NOT have an "M pattern."
Sincerely,
Tony Leukeringcurrently Fairborn, OH
