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.
Hoary-headed Grebe
Hoary-headed Grebe (Poliocephalus poliocephalus) is a small 27–30 cm grebe endemic to Australia and southern New Guinea. Distinctive pale grey and white head with fine dark streaking giving 'hoary' appearance; chestnut neck sides. Inhabits open freshwater lakes and reservoirs. Highly nomadic, following rain across the arid interior.
