The Steppe Eagle (Aquila nipalensis) is a bird of prey. It is about 2-3 ft from head to tail. It has a wingspan of at least 5 ft - 7ft. Females, weighing upto 5 kg are slightly larger than males.   It was once considered to be closely related to the non-migratory Tawny Eagle(Aquila rapax) and the two forms have previously been treated as conspecific. They were split based on pronounced differences in morphology and anatomy.

The Steppe Eagle breeds from Romania east through the south Russian and Central Asian steppes to Mongolia. The latter are the one that visit Malaysia and SEA countries.

This is a large eagle with brown upperparts and blackish flight feathers and tail. This species is larger and darker than the Tawny Eagle, and it has a pale throat which is lacking in that species.
Immature birds are less contrasted than adults, but both show a range of variation in plumage colour. The eastern race A. n. nipalensis is larger and darker than the European and Central Asian A. n. orientalis.
Large numbers are seen at certain places such as Khare in Nepal during migration of Nov & December.

The Steppe Eagle's diet is largely fresh carrion of all kinds, but it will kill rodents and other small mammals up to the size of a hare, and birds up to the size of partridges. It will also steal food from other raptors. Like other species the Steppe Eagle has a crop in its throat allowing it to store food for several hours before being moved to the stomach.

The call of the Steppe Eagle sounds like a crow barking, but it is rather a silent bird. The Steppe Eagle is the national animalof Egypt.
