Elephant bird

Elephant birds were extinct, flightless birds in the family Aepyornithidae, native to Madagascar. Some species were among the largest birds known and laid exceptionally large eggs.

Aepyornithidae: A family of extinct, flightless birds endemic to Madagascar, including elephant birds. This family name identifies the taxonomic group to which elephant birds belong.
Aepyornis maximus: An extinct elephant bird species from Madagascar, historically considered among the largest birds ever known. It is the species most often associated with the elephant bird’s enormous stature.
Paleognath: A member of Palaeognathae, the bird lineage that includes ratites and tinamous. Elephant birds belong to this lineage despite their flightlessness and island distribution.
Holocene extinction: The ongoing loss of species during the current geological epoch, accelerated by human activity. Elephant bird extinction is part of Madagascar’s broader late-Holocene loss of large animals.
Ratite: A traditional grouping of mostly large, flightless birds with reduced or absent keels on the breastbone. Elephant birds share flightlessness with the birds traditionally grouped as ratites.
Vorombe titan: An extinct elephant bird species described from Madagascar and recognized as exceptionally large. Its recognition refined estimates of the largest elephant bird body sizes.
Tinamous: A group of ground-dwelling birds native to Central and South America, most of which can fly. Genetic comparisons with tinamous helped reveal unexpected relationships among paleognath birds.
Megafauna: Large-bodied animals, especially those prominent in discussions of extinction and ecological change. Elephant birds were among Madagascar’s largest animals and part of its lost megafauna.
Palaeognathae: A major lineage of birds that includes ratites and the flying tinamous. Genomic evidence places elephant birds within this broader bird lineage.
Aepyornis hildebrandti: An extinct elephant bird species known from fossil remains in Madagascar. It illustrates that the family included species distinct from the largest forms.
