Media notes

Front view showing thin white neck with no dark colors interrupting it as in the other grebe's, save Clark's.

Observation details

Longer serpentine necked grebe approximately 2 -3 times head height above Red-breasted Merganser. Long, thin neck with white in front and extending into side of neck. White of neck extending uninterrupted to white lower face of head without any trace of dark color of rear neck extending forward into white neck below head as in all other Grebes, save Clark's. A distinction which at this location is enough to ID it as a Western Grebe. Black only on posterior of neck with separation of colors distinct. Black cap to head extending just beneath red eye and then forward to lower mandible, similar as in Horned Grebe, but neck much longer, thinner, and whiter. Yellowish bill longer and more sharply pointed than in Horned Grebe which had a grayish bill. Behavior also differed: when Western Grebe would dive it would lift itself partially out of water as if springing to dive and extensively curl it's neck. Horned Grebes diving behavior did not involve this accentuated curling of the neck or lifting of the body prior to diving, probably due to lower body mass and shorter neck of Horned Grebe.
