The tops of elephant bird skulls display punctuated marks, which may have been attachment sites for fleshy structures or head feathers. [18] Mullerornis is the smallest of the elephant birds, with a body mass of around 80 kilograms (180 lb), [16] with its skeleton much less robustly built than Aepyornis. [19]
Aepyornis is an extinct genus of elephant bird formerly endemic to Madagascar. The genus had two species, the smaller A. hildebrandti and the larger A. maximus, which is possibly the largest bird ever to have lived. [2] Its closest living relative is the New Zealand kiwi. [3]
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
In his landmark publications, such as the Systema Naturae, Carl Linnaeus used a ranking scale limited to kingdom, class, order, genus, species, and one rank below species. Today, the nomenclature is regulated by the nomenclature codes. There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, and species.

The largest bird in the fossil record may be the extinct elephant birds (Vorombe/Aepyornis) of Madagascar, which were related to the ostrich. They exceeded 3 m (9.8 ft) in height and 500 kg (1,100 lb) in weight. [44] The last of the elephant birds became extinct approximately 1000 years ago.
This category lists orders of birds (ending in "-formes") as categories, and pages dealing with certain (non-taxonomic) groups of birds. The first section links to categories listing lower taxonomic levels in birds. In the second section, higher categories such as superorders, and basal groups are listed.
