About These Birds
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.
White-tufted Grebe
White-tufted Grebe (Rollandia rolland) is a small 22–27 cm grebe of southern South America, from Peru and Bolivia south to Tierra del Fuego. Dark brown with distinctive white facial tufts extending from cheeks; chestnut neck sides. Inhabits freshwater lakes, bogs, and slow rivers. Partially migratory; nomadic in austral winter.
