About These Birds
Clark's Grebe
Clark's Grebe (Aechmophorus clarkii) is a large 55–74 cm grebe of western North America, recently split from Western Grebe. White surrounds red eye (vs. black in Western Grebe); bright orange-yellow bill. Inhabits large freshwater lakes with tule and cattail margins; winters on coastal seas. Performs identical rushing-water display with mate.
Atitlan Grebe
Atitlan Grebe (Podilymbus gigas) is an extinct large flightless grebe formerly endemic to Lake Atitlán, Guatemala. Similar to Pied-billed Grebe but larger, with heavier bill and flightless wings. Extirpated by the 1980s due to introduced bass predating chicks, reed-bed destruction, and hunting. Last confirmed individuals died in the early 1990s.
