Rollandia microptera (Titicaca Grebe)

Synonyms: Podiceps micropterus; Rollandia micropterum; Rollandia micropterum micropterum

Wikipedia Abstract

The Titicaca grebe (Rollandia microptera), also known as the Titicaca flightless grebe or short-winged grebe, is a grebe found on the altiplano of Peru and Bolivia. As its name implies, its main population occurs on Lake Titicaca. Lake Uru Uru and Poopó, the Rio Desaguadero, and small lakes that connect to Lake Titicaca in wet years, serve as "spillovers" territory. In the past, the population was larger and several of these lakes – such as Lakes Umayo and Arapa – apparently had and may still have permanent large colonies (BirdLife International 2006). It is sometimes placed in Podiceps or a monotypic genus Centropelma. Its local name is zampullín del Titicaca.
