About These Birds
Horned Grebe
Horned Grebe (Podiceps auritus) is a medium 31–38 cm grebe of the Holarctic. Breeding: black and chestnut body with golden-buff 'horn' tufts on sides of head; red neck. Winters grey and white on coastal seas. Breeds on ponds and lakes in boreal and temperate zones; migratory. Wingspan to 65 cm. Vulnerable in Europe due to lake eutrophication.
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.
