The last confirmed sighting of the Colombian Grebe (Podiceps andinus), now considered to be extinct, was at Lake Tota.

The Colombian Grebe (Podiceps andinus), was a grebe (aquatic bird) found in the Bogotá wetlands in the Eastern Andes of Colombia.

The decline of the Colombian grebe is attributed to wetland drainage, siltation, pesticide pollution, disruption by reed harvesting, hunting, competition, and predation of chicks by rainbow trout (Salmo gairdneri) (del Hoyo et al. 1992).
