Description of the Bird
On July 13th we were told by Valentina Roumi that there were 2 RNGRs on the lake. We relocated one swimming and one on what appeared to be a mound/nest. When we returned on July 28th, we viewed one adult swimming with and feeding three juveniles. Sex was indeterminable. The adult was in breeding plumage (red neck with silvery chin/cheek patch) and the juveniles were the same medium shade of brown throughout. Dagger shaped bill was distinct but it was difficult to determine the color of the bills.

Similar Species Discussion
There were plenty of Eared Grebes on the lake, but these were larger with solid red neck, silver cheek patch, and did not have ear turfts. The birds were smaller and not black and white like Western Grebes or Clark's Grebes.
Previous Experience
Red necked grebes are not extremely common in Colorado like Eared Grebes and/or Western Grebes. I see them annually, but chase them when they are reported. It is interesting to see them raise a brood when their normal breeding range is Northern Montana, Canada, and Minnesota.
