What are deck feathers?

Deck feathers refer specifically to the central pair of tail feathers on a bird. These feathers play a crucial role in a bird's ability to maneuver and maintain balance during flight. The central pair, often longer than the others, contribute to the aerodynamics of flight and help in steering and controlling the bird's movement.

While the outermost feathers of the wings, the feathers on the legs, and the feathers covering the body are all important for various aspects of a bird's physiology and behavior, they do not fit the specific definition and role associated with deck feathers. Understanding this distinction is essential for anyone involved in falconry, as the health and maintenance of these feathers can directly impact a bird's flying capabilities.
