These pennant feathers grow to greater lengths in successive years, up to twice the body length. They are dropped or broken off quickly upon completion of breeding. With the distal (9th) and proximal (1st - 3rd) primaries being longest, the wings of male birds are distinctly angular.
Red kite (Milvus milvus) in flight, showing remiges and rectrices. Flight feathers (Pennae volatus) [1] are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (/ ˈ r ɛ m ɪ dʒ iː z /), singular remex (/ ˈ r iː m ɛ k s /), while those on the tail are called rectrices (/ ˈ r ɛ k t r ...

These large feathers have been postulated as a feature developed through intense sexual selection. [5] Outside the breeding season, the female is distinguished from the male by its smaller size and similarity to the pennant-winged nightjar, notably the patch of white on the throat and dark barring on the belly.

Feather development occurs in the epidermal layer of the skin in birds.It is a complicated process involving many steps. Once the feathers are fully developed, there are six different types of feathers: contour, flight, down, filoplumes, semiplumes, and bristle feathers.

Pennaceous feathers on the wing, and elsewhere, where stresses related to flight, or other activities, are high, are accordingly attached especially strongly. This strong attachment is accomplished by ligaments under the skin, which in some birds and other feathered dinosaurs results in raised bumps or marks along the rear forelimb bone .
