The two central feathers on a bird's tail are called?

The two central feathers on a bird's tail are called tail feathers. Tail feathers, which are also known as rectrices, play a crucial role in a bird's flight and balance. They provide stability and help with steering during flight. The arrangement and condition of these feathers can also impact a bird's ability to perform various maneuvers.

In contrast, the other terms refer to different parts or categories of feathers. Primary feathers are the main flight feathers located on the outer part of the wings and are essential for flying. Secondary feathers are found closer to the bird's body on the wings and serve a similar function, aiding in lift and gliding. Deck feathers are not a commonly recognized term in the study of avian anatomy and do not refer specifically to the two central tail feathers.

Understanding the specific terminology is important in falconry, as it helps falconers communicate about the birds effectively and ensures proper care and management of the birds' health and training.
