[cobirds] Brant update at Chatfield
Cheryl Tooten just phoned me (12:25, MST) to say that the two (Atlantic) BRANT are readily visible a few yards off-shore from the NEW Heron Overlook, in Chatfield State Park. This spot is south of the OLD Heron Overlook. If you are not familiar with the location, refer to a map at either park entrance. As was stated before, this pair are of the Eastern, or Atlantic flavor of Brant, rarely seen in Colorado. Black or Pacific style Brant are the kind we see more often, and those are rare enough. AND the two Brant subspecies will likely be split into two valid, independent (Countable) species, in parallel with the recent split of Cackling Goose from Canada Goose. So if possible, make for the shores of beautiful Chatfield Reservoir (State Parks pass required or pay a day fee of $8). Once the split occurs, you can proudly augment your state lift, life list, day list, whatever, by ONE.

[cobirds] Brant Split
Greetings All, I am probably not up-to-date on the very most recent Brant stuff, but from what I do know, I doubt that the Brant will be split really soon, and what lines they'll be split along. In reality there are 5 populations: 1- Black Brant. Breeds in AK and Siberia (and I am too lazy to dig this up, but probably westernmost Canada), and winter along North American Pacific Coast from BC to Baja 2- Western High Arctic Brant. AKA Gray-bellied Brant. Limited to islands in w. Canada's Arctic. Winter mostly in Washington's Puget Sound, with a goodly number of Black Brant. 3- Eastern High Arctic Brant. These are part of Atlantic Brant and winter mainly in and around Ireland. The breed in e. Canadian Arctic. 4- Eastern Low Arctic Brant (I forget the official name for this population). They winter on the North American Atlantic Coast and breed along Hudson Bay and nearby areas. 5- Black-bellied Brent Goose. Breed in Siberia and winter primarily in Europe Black Brant have recently extended their range westward in Siberia, and were they meet Black-bellied Brent Goose, they interbreed with some frequency (or so is my understanding). Notably, Black Brant from these colonies have been banded and found along the North American Pacific Coast. There are a couple records of apparent hybrid Black Brant x Black-bellied Brent Geese along the Pacific Coast of North America as well Gray-bellied Brant. Their mtDNA fits in with Eastern High Arctic Brant, but I am not certain if they've been compared with the other Atlantic Brant. Notably, nuclear DNA shows a clear infusion of Black Brant genes (the females tend to loyally return to the breeding grounds with mate in tow; the male might be from a totally different population). I am unclear if there has been any genetic comparison between Eastern High Arctic and Eastern Low Arctic Brant. Habitat wise, Eastern High Arctic and Western High Arctic Brant are very similar to each other and somewhat different from the other Brant populations. Visually, there is nearly complete overlap between the two populations of Atlantic Brant and Gray-bellied Brant with the darkest Eastern High Arctic Brant falling about mid-range in the phenotypic spectrum of Western High Arctic Brant, and the palest Western High Arctic Brant (Gray-bellied) matching the palest Atlantic Brant. Confused? It is confusing. There are 5 populations. Interbreeding between 4 likely occurs, with only the Eastern Low Arctic population being isolated. Black Brant and Western High Arctic Brant (Gray-bellied) overwinter together Black-bellied Brent Goose and Eastern High Arctic Brant overlap in their wintering grounds. Black-bellied Brent Goose and Black Brant interbreed where their breeding ranges meet. Thus, for all of the pairings above, it seems that some degree of interbreeding occurs. How much is unclear. However, it makes for a very muddled picture, and if these will be split is not known, and if they are split, how they will be split is another question. Remember, Gray-bellied Brant has yet to be formally named in the scientific literature. Rather than being similar to the Canada/Cackling Goose picture, the Brant picture actually is rather like that of Greater White-fronted Goose, with 2-3 subspecies in North America (one of which extends into Siberia), a European subspecies, and one in Greenland. Not sure if all this esoteria is of interest to anyone, but there is the picture as I understand it (Based mainly on info about 5 years old). The goose biologists I talked to seemed skeptical of splitting into separate species at that time. Which does not make the Brant at Chatfield less interesting. They are almost certainly from one of the High Arctic populations, and definitely not of our usual sort here in CO Cheers Steven Mlodinow Longmont CO -- You received this message because you are subscribed to the Google Groups Colorado Birds group.

[cobirds] Red-throated Loon still present at Hamilton Res. (Larimer) on 3Dec2011
The adult basic RED-THROATED LOON was still present this afternoon at Hamilton Reservoir (Rawhide Power Plant), north of Buckeye Road west of I-25 Exit 288 (Larimer County). Today, viewing from the Observation Overlook on the south side of the res and looking across to the plant, it was somewhat left of the big stack, in loose association with about 20 Western Grebes. The grebes are about the same size, with the loon being slightly thicker-necked and longer-bodied, and always with that bill pointed slightly upward. Their diving may be another point of differentiation from long distance, with the grebes being quicker and getting air on the way in, the loon just rolling into the dive. If anyone knows of previous Larimer County records for this species, I would appreciate hearing details. Thanks. Other birds of note at Hamilton Res today were: Redhead (1 female) Ross's Goose (I think, 1 white a long ways off east of the stack with Canada/Cackling Geese) Snow Goose (1 blue) Bald Eagle (1 adult) Horned Grebe (15+) Dave Leatherman Fort Collins -- You received this message because you are subscribed to the Google Groups Colorado Birds group.

[cobirds] Union Little Gull Weld Cty--NO
I arrived at Union about 45 minutes after the reported Little Gull. Unfortunately, many of us were unable to relocate the bird even though having birders positioned at various points around the lake. I finally put up the white flag around 4pm. I did have a wintering Vesper Sparrow near the SW observation deck with a group of Tree, Song, and White-crowned Sparrows. This might be of interest if the lake is covered by the Christmas Bird Count.

[cobirds] Photos of Little Gulls, Union Res (Weld)
As Mark said, a concerted cooperative effort by numerous birders to observe the Little Gulls this afternoon (after 2 pm) failed. I think the juv. was last seen flying towards the east at about 1:30. I don’t know when the adult was last seen. As no one has posted links to photos of these rare gulls, I am offering my witness (poor quality) shots from 1 December. I’m sure better ones are out there. Birders at other lakes tomorrow should watch for these, as I believe they have left Union Res. If they reappear at Union, they may be moving back and forth to another location, perhaps a nocturnal roost spot.

[cobirds] Sandhill Cranes - BCLP - Jeffco
About 2:30 this afternoon as I was checking out the lake from Pelican Point in Bear Creek Lake Park (BCLP), I had a small flock of 14 Sandhill Cranes fly over the lake from east to west. Last I saw of the flock they were headed toward the foothills. Seems a little late and normally I see them traveling to the south this time of year.

Re: [cobirds] Brant Split
Thanks to Steve for this fascinating review of Brant population distribution. The suggestion that the Chatfield birds are from the “high Arctic” population is interesting and seems to make sense given the migration patterns of other high arctic Branta species, such as Richardson’s Cackling Goose. I noticed that Robb Hinds and Glenn Walbek’s photos of the Chatfield birds show wings extending slightly beyond the tail. My photos of Eastern Low Arctic Brant wintering in Rhode Island show tail extending beyond the wing-tips. The long wings of the high Arctic birds are consistent with longer-distance migration, relative to the migration distance required for low-Arctic Brant. I wonder if this difference is discussed in the Brant literature (I admit I have not done my homework on this question). So, if pale Eastern birds winter in Ireland, and darker Western birds winter in the Pacific Northwest, what about the paler western birds that Steve refers to. Do pale ones ever show up in the Pacific Northwest? Do birds of the Irish wintering-population ever show up in the USA in winter?

[cobirds] Chatfield Saturday
Hi went this afternoon. Roads were mostly clear. Got there at 2:40PM Checked old Heron observation lot no cars then. Went to Model air plane field. One birder was parked there observing 2 male winter Lapland Longspurs on ground at the dumpster. There was also a flock of colorful Horned Larks (about 20) nearby at the viewing area. Very active seemed to like skimming the snow. Went thru the campground D nothing. At the registration station had 16 Robins in the 2 trees along with 2 Starlings and a magpie. Going back by the Heron park lot there were now 6 cars there. A fellow name of Hutch offer to help me. When we got nearer to the observation deck there were several observers. The two Brant were near shore and had moved around to north side where the shore curves back and was too steep for me to go down . So I bailed out. If still there and if Tuesday birders do not cancel it will be cold (35 by noon) I will try again. Been many many years since I have seen a pale bellied Brant in Colorado. May not be split in my Lifetime! Good birding today Bob Spencer N.E. of Golden -- You received this message because you are subscribed to the Google Groups Colorado Birds group.

[cobirds] Brant Redux
Greetings All, I may have sowed the seeds of confusion Black Brant: breed w. Canada to eastern or central Siberia. Winter mostly along Pacific, in North America, from BC south to Baja California Sur. Vagrant have shown up all across the n. Hemsiphere Black-bellied Brent Goose. Breeds Siberia. Winters Europe. Vagrant to North American Atlantic Coast. Apparent hybrids with Black Brant have appeared in Pacific NW. Individuals of this population have been found migrating between Ireland and Canada but never actually on the eastern Canadian breeding grounds. Gray-bellied Brant. Breeds Western High Arctic in Canada. Winters primarily in Puget Sound area. Vagrants, apparently of this taxa have appeared in Europe, California, perhaps elsewhere Eastern High Arctic Brant. Breed in Eastern High Arctic of Canada. Winter primarily in Ireland/British isles. Vagrants around Europe, probable farther east. Since lumped with Eastern Low Arctic birds, and look very similar, who knows where they've wandered to. Eastern Low Arctic Brant. Breeds farther s. in eastern Canada. Winters on North American Atlantic coast. Hard to know if interior Atlantic Brant pertain to low or high arctic birds, or both. Finally, Gray-bellied Brant can be as pale as any Atlantic Brant, so birds that appear to be Atlantic Brant that have appeared on Pacific Coast are assumed to be from the GB Brant population, but ???
