The Clark's Grebe (Aechmophorus clarkii) was, until recently, considered a subspecies of the Western Grebe (A. occidentalis). Clark's is similar in appearance, behavior and vocalizations to the Western Grebe, but shows a more orange colored bill and its eye is typically in the white area of the face, while Western Grebes have a more olive colored bill with the eye in the dark part of the face. There are exceptions to these generalities, but basically, those are the visual differences. The photos on this page were taken at Balmorhea Reservoir, Reeves Co., Texas with a Canon EOS 1D Mark II and an EF 600mm F/4 L IS lens and 1.4X extender in November, 2005.

The two Clark's Grebe shots below were taken at Balmorhea Lake, Reeves Co., Texas, in November, 2006, with a Canon EOS 1D Mark II and EF 600mm F/4 L IS lens and 2X extender.

	The next 3 images of Clark's Grebe were taken at Bear River N.W.R., Box Elder Co., Utah, in June, 2007. These shots were taken with a Canon EOS 1D Mark III and EF 600mm F/4 L IS lens and 2X extender.
