The Alaotra GrebeTachybaptus rufolavatus is a grebe found only on Lake Alaotra and surrounding lakes in Madagascar. The last sighting was in 1985 and it may well be extinct, but all areas of remaining habitat have yet to be thoroughly searched.

Grebes are members of the Podicipediformes, a widely distributed order of freshwater diving birds, some of which visit the sea when migrating and in winter.
Grebes are small to medium-large in size, have lobed toes, and are excellent swimmers and divers.
Grebes have narrow wings, and some species are reluctant to fly; indeed, two South American species are completely flightless.
