观察细节
The bird was first seen the previous day on Dec 4 by Gus van Vliet. The bird was relocated at this time and I was able to view the bird along with Gus, Bev Agler and Patty Rose. We saw the bird close to a Horned Grebe and made reasonable comparisons and noted differentiating characters and obtained poor photographs. The head shape and dark coloration on the side of the face was distinctly different from the Horned Grebe; the bird was basically the same size as the HOGR, and had a smallish, thin bill, but the forehead was steeper and head with a "peak" compared to the flatter head of the HOGR. The bird made repeated dives.
