Urling and I just spent a half hour looking at a probable Red-necked Grebe, at the far north side of the Walker gravel pit near Franktown.
It had the shape of an RNGR, with a particularly noticeable long, pointed, dagger-like, yellow to yellow-orange bill. Size of a goldeneye but slimmer. General pattern matches the winter adult.
Its Ggay cap fades to whitish below the eye. We looked for & could not pick out a whitish vertical patch behind the eye. Gray-black back; whitish breast when it rose to wave its wings. But also: a white wing patch that showed consistently; RNGRs have white secondaries but none of the field guides show that on a bird on the water.
It resembles the winter adult shown in an Eastern Peterson field guide that we have.
It floated along the water, dove occasionally and caught food.
