About These Birds
Red-necked Grebe
Red-necked Grebe (Podiceps grisegena) is a medium 40–50 cm grebe of Eurasia and North America. Breeding plumage: rich chestnut-red neck and breast; grey-white cheeks; black cap; yellow-based bill. Inhabits freshwater lakes; winters on coastal seas. Wingspan to 85 cm. Migratory; breeds in boreal zone, winters on coastal waters.
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.
