Default Clark's Grebes

I think these are Clark's Grebes. It is difficult to tell them apart from the Western Grebes. Can anyone verify the ID?

Very nice shots.
I can confirm that these are Clark's, although the head pattern is somewhat ambiguous. Typically the eyes are completely surrounded by white in Clark's, and by black in Westerns, but the bill color is the clincher - it is yellow-orange in Clark's and yellow-green in the Western. The only white remaining near the eyes in these is on the lores (spot in front of the eyes) which is white in Clark's and usually black in Westerns. These are a pair - the one with the larger bill is the male.

Thanks again! You help me to clear up the confusion between the 2 types of Grebes, I need all the help I can get since I only have done it for a short time in taking pictures of birds and water fowls.
