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.
Madagascar Grebe
Madagascar Grebe (Tachybaptus pelzelnii) is a small 25–29 cm grebe endemic to freshwater lakes and wetlands in Madagascar. Pale brown with rufous neck sides; paler than Little Grebe. Inhabits lakes and reservoirs including Lake Alaotra and Lake Ihotry.
