Elephant bird "A. maximus" and "D. stirtoni" were revised to 540 and 730 kg, respectively. Four species are usually accepted in the genus "Aepyornis" today, but the validity of some is disputed, with numerous authors treating them all in just one species, "A. maximus". Up to three species are generally included in "Mullerornis". Several ratites outside of Madagascar have been posited as "aepyornithid"-like and could potentially make this clade considerably more speciose. These include "Eremopezus" from the Eocene of North Africa, unnamed Canary Island remains and several Neogene taxa in Eurasia. "Aepyornis maximus" is commonly known as the 'elephant bird', a term

In the early 1990s, the estimated wild populations included: There are a total of 138 state elephant corridors, 28 interstate corridors and 17 international state corridors where Indian elephant populations are found. The table below enlists the corridors. Elephants are classified as megaherbivores and consume up to of plant matter per day. They are generalist feeders, and both grazers and browsers. In a study area of in southern India, elephants were recorded to feed on 112 different plant species, most commonly
