1. n. A quill or flight feather of a bird's wing.

Century Dictionary and Cyclopedia

1. n. In ornithology, one of the flight-feathers; one of the large stiff quill-feathers of a bird's wing which form most of its spread and correspond to the rectrices or rudder-feathers of the tail. They are distinguished from ordinary contour-feathers by never having aftershafts, and by being almost entirely of pennaceous structure. They are divided into three series, the primaries, the secondaries, and the tertiaries or tertials, according to their seat upon the pinion, the forearm, or the upper arm. See diagram under bird.
