Which raptor term refers to a bird raised in captivity?

The term that refers to a bird raised in captivity is "eyas." This terminology originates from the practice of falconry, where raptors are often bred for hunting purposes. An eyas specifically denotes a young bird of prey that has been hatched and reared in a controlled environment, such as a breeding facility or by a falconer.

In contrast, a passage raptor indicates a bird that has fledged (developed feathers for flight) but has not yet been fully trained or tamed. These birds are typically caught in the wild during their migratory journey. A falcon is a general term that encompasses various species of birds in the family Falconidae, which includes eyases and other raptors but does not specifically denote a captive-raised bird. A haggard refers to an adult bird that has been caught from the wild, emphasizing its sophisticated characteristics and experience in flight, which distinguishes it from the young, captive-raised eyas. Understanding these terms helps in the appreciation of raptor ecology and training practices within falconry.
