| 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. |
