What does the term "eyass" refer to?

The term "eyass" refers specifically to a young raptor that has recently fledged or is still in the nest and not yet fully trained. In falconry, it often denotes a bird that is raised from a nestling stage, which means it is captured and trained from a very young age. This early stage of development allows falconers to imprint their training techniques and establish a bond with the bird, which can significantly influence the bird's behavior and performance in the field. The other options don't align with the definition of "eyass": a fully grown raptor refers to a mature bird, a hunting technique of falcons describes the methods they use for hunting, and the nest of a hawk pertains to the physical location where the birds are reared, but none of these directly define "eyass."
