The species Colombian Grebe is extinct. |
|
- Podiceps andinus
Identification
Very similar to Black-necked Grebe except with a chestnut foreneck and upper breast, rather than black.
Distribution
South America: formerly Andes of Colombia. Extinct; last reported 1977 at Lake Tota (3015 m altitude). Subsequent surveys in the early 80's failed to find the species.
Taxonomy
This is a monotypic species[1]. Although still retained as a species in most listings[1][2][3], recent genetic studies suggest it would have been better treated as a subspecies of Black-necked Grebe Podiceps nigricollis, being particularly closely related to the North American subspecies P. nigricollis californicus[4]
Habitat
Freshwater wetlands, pools and lakes.
Behaviour
Presumed to have been similar to Black-necked Grebe; extinction possibly due to competition from introduced trout, and/or to fertiliser pollution from surrounding farmland[2].
