What are the flight feathers located between the body and the primaries known as?

The flight feathers located between the body and the primaries are known as secondaries. These feathers play a crucial role in a bird's ability to fly, as they contribute to the wing's surface area and aid in lift and maneuverability during flight.

Understanding the anatomy of a bird's wing is essential for anyone involved in falconry or bird care. The primaries, which are the outermost flight feathers, provide propulsion, while the secondaries enhance lift and stability. This distinction in feather types is vital for ensuring the health and capability of a bird in flight, highlighting the importance of knowledge regarding avian anatomy in falconry practices.

The other terms listed, such as flappers, tertials, and sails, refer to different concepts or parts of a bird's wing or are not commonly used in formal avian anatomy. Tertials, for instance, are the feathers located closer to the body than the secondaries, while sails do not specifically pertain to feather classification.
