About These Birds
Great Crested Grebe
Great Crested Grebe (Podiceps cristatus) is a large 46–51 cm, elegant grebe of Eurasia, Africa, and Australasia. Breeding plumage: elaborate chestnut and black head crest and ruff; white face; reddish-pink bill. Inhabits large freshwater lakes and reservoirs; winters on coastal seas. Wingspan to 90 cm. Famous for mirror-display courtship dance.
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.
