What is an eyass?

An eyass refers specifically to a young raptor, typically one that is still a nestling and has not yet fledged. This term is often used in falconry to describe birds that have been taken from the nest for training. Eyasses are usually considered valuable by falconers because they can be hand-raised and trained from a young age, establishing a strong bond with their handler. This connection can lead to more effective training and improved hunting skills as they mature.

The concept of an eyass emphasizes the importance of early development in a raptor's training journey, making it distinct from adult birds or those captured from the wild. In contrast, the other options refer to different stages or types of birds relevant to falconry but do not accurately define the term "eyass."
