What do you call offspring from two raptors held in captivity?

Offspring from two raptors held in captivity are referred to as "captive-bred." This term specifically applies to birds that are bred in a controlled environment, such as in a falconry setting or a breeding facility, rather than being born in the wild. Captive breeding is often practiced to preserve species, promote specific traits, or ensure a steady supply of birds for falconry and conservation efforts.

The other terms refer to different contexts in the world of raptors. "Eyas" specifically designates a young hawk or falcon that is still in the nest, which does not encompass the broader idea of breeding in captivity. "Passage" describes juvenile raptors that are in their first year and are migrating or have recently fledged, indicating a wild origin rather than a captive situation. "Wild raptors" refers to birds living freely in their natural habitats, which is clearly different from those bred or raised in captivity. Understanding these distinctions helps clarify why "captive-bred" is the most accurate term for the offspring of raptors held in captivity.
