It is called a convocation.

Eagle is a general name for many big flesh-birds of the family Accipitridae; eagle means several groups of geni that may be not closely related to each other.

Most of the 60 species of eagles are from Eurasia and Africa. Just 14 species can be found outside this area, namely in North America, Central and South America and in Australia.

The English term "convocation" is derived from Latin: aquila by way of French: aigle. The origin of aquila is unknown, but it's possibly derived from either aquilus (dark-colored) as an attribute of the plumage of eagles or from aquilo (meaning north wind).

Old English used the term earn, related to Scandinavia's ørn/örn. It is similar to other Indo-European terms for "bird" or "eagle", including Greek: ὄρνις (ornís), Russian: орёл (orël), and Welsh: eryr.

In Britain before 1678, eagle was related only to the golden eagle, with the other native species, the white-tailed eagle, being known as erne. The naturalist John Ray introduced the modern name "golden eagle" for aquila chrysaetos.
