What are the long feathers of a hawk's wing known as?

The long feathers of a hawk's wing are appropriately referred to as quills. These quill feathers are essential for flight, providing the necessary lift and aiding in maneuverability. Quills have a stiff structure, which contributes to the aerodynamic shape of the wing and allows birds to achieve the speeds and agility that characterize raptors.

Coverts, while part of the wing, serve a different purpose. They are shorter feathers that cover the base of the longer flight feathers, helping to smooth the contour of the wing.

Beam feathers do not represent a standard term in ornithology pertaining to a bird's wing structure, which may lead to confusion.

Tail feathers refer specifically to feathers located on the tail rather than the wings. These feathers are also crucial for balance and steering during flight, but they are not involved in the wing’s structure.

Understanding the specific terminology used in falconry and ornithology is vital for recognizing the anatomical features and their functions in birds like hawks.
