About These Birds
Southern Silvery Grebe
Southern Silvery Grebe (Podiceps occipitalis) is a small 28–34 cm Andean and sub-Antarctic grebe. Pale silvery-grey face and neck contrast with darker grey cap; yellow eye. Inhabits high-altitude Andean lakes in Peru, Bolivia, Chile, and Argentina, also Falkland Islands. Locally common at altitude. Feeds on small invertebrates and fish.
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.
