Encyclopedic overview
The Atitlán grebe (Podilymbus gigas), also known as the giant grebe, giant pied-billed grebe or poc, is an extinct species of grebe. A relative of the pied-billed grebe, it was endemic at the Lago de Atitlán in Guatemala at an altitude of 1700 m. It was described in 1929 by Ludlow Griscom based on a specimen collected in 1926 and had been overlooked in the past. American ecologist Anne LaBastille observed the decline of this species over a period of 25 years. It was declared extinct by 1990.
