Alaotra Grebe

The Alaotra grebe, also known as Delacour's little grebe or rusty grebe, is a recently extinct grebe that was endemic to Lake Alaotra and its surrounding lakes in Madagascar. Experts say that the grebe became extinct after carnivorous fish were introduced into its native habitat. The last sighting of the Alaotra grebe was in 1983 or 1985 and it was officially declared extinct in 2010.
