Description of the Bird

This is to document a Red-necked Grebe that appears to be wintering in Colorado.

Large grebe, smaller than Aechmophorus grebes but significantly larger than the three small CO grebes.

Head distinctive with STOUT yellowish bill, which bird held at a downward angle, dark cap, large whitish gray cheek patch, thick curved brownish neck that had some rufous tones in it (although the photo does not show such) flanks, brownish and back dark brown.
Behaviors: Swimming in a cove with Clark's Grebe.
Call: none heard
Plumage: winter adult

Similar Species Discussion

Clark's and Western Grebes

Both have long thin bills, the former a smart yellow orange, the later a dullish green-yellow.

Both have longer and thinner necks than this bird.

Both have white necks that contrast sharply with the hind neck unlike the dull shorter thick neck of this bird with much less contrast between the red brown of the neck sides and the dull brown of the hindneck. This bird was noticeably shorter in length than the two Aechmophorus grebes and squatter in appears due to the shorter neck of this bird. The bird was seen within 3 feet of a Clark's Grebe for excellent comparisons.

Previous Experience

I have seen mostly breeding adults in Alaska, but saw one Red-necked Grebe at the same location, PUeblo Res, in December of 2006, and it could in fact be the same bird.
