About These Birds
Colombian Grebe
Colombian Grebe (Podiceps andinus) is an extinct small to medium grebe formerly endemic to Lake Tota in the eastern Andes of Colombia at 3,000 m. Related to Black-necked Grebe; had chestnut neck and facial tufts. Declared extinct in 1977 following drainage of much of Lake Tota, hunting, and pesticide use.
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.
