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.
Least Grebe
Least Grebe (Tachybaptus dominicus) is the smallest New World grebe at 21–27 cm. Dark grey overall in breeding plumage with yellow eye, blackish cap, and short bill. Inhabits small freshwater ponds, ditches, and marshes from the southern USA through Central and South America to northern Argentina. Feeds on small fish and aquatic invertebrates.
