flight feather

Any of the comparatively large, stiff feathers of a bird's wing or tail that are necessary for flight.


1. skin appendages of all birds. Comprise a central shaft with a flat vane on either side. The shaft consists of the calamus, embedded in the feather follicle, and the rachis which is outside the follicle. The calamus has an opening at each end, the superior and inferior umbilicus. The inferior umbilicus contains the dermal papilla which produces the pulp which continues up the interior of the calamus to end at and pass out through the superior umbilicus. Each feather has two parts, the mainfeather and a small afterfeather which is attached at the superior umbilicus. Barbs and barbules form the bulk of the vane.
Contour feathers are large feathers that give the bird its shape. Down feathers are very small feathers. Semiplume feathers are intermediate in size between contour and down. Filoplume feathers are hairlike and remain after other feathers are plucked. They have only one small tuft of barbs. Specialized additional feathers include auricular feathers, around the ear lobes, oil gland feathers, at the oil gland on the tail, bristle feathers on the eyelids and powder feathers in aquatic birds. Remiges are the large flight feathers of the wing and rectrices the very long contour feathers coming from the side of the tail. These are the longest feathers of all in the domestic fowl.
The feather coat consists of feather tracts (see below) or pterylae that are well defined and carry contour feathers and semiplumes. They are separated by unfeathered tracts called apteria. The distribution of special feathers of particular colors in particular pterylae is what gives the breeds their distinctive appearance. The feather coat is divided up into regions that include hackle, cape, cushion, saddle, wing bars, wing fronts and wing bows.
2. long hairs on the fetlocks of draft breeds of horses and in dogs, on the ventral body, caudal aspect of the legs, and ventral tail of spaniels and setters.
3. hair-streams that produce feather-like marks, in the haircoat of an animal.

feather clipping
clipping the flight feathers with tin shears will prevent flight for several months.
feather coat
the total feather covering of a bird. Called also ptilosis.
contour feather
the externally visible feathers which determine the bird's silhouette and the contours of the wings, body and tail.
feather cushion
the plumage from the pelvic tract of the hen, forming the back cover.
feather cysts
contain unerupted feathers and keratinous debris that may form large cutaneous lumps.
feather disease
an idiopathic disease of all varieties of cockatoos, lovebirds and budgerigars as young birds and characterized by a chronic, progressive, symmetrical loss of feathers, elongation of toenails and upper beak, which later becomes necrotic and sloughs off. Called also psittacine beak and feather syndrome.
filoplume feather
hairlike feathers, commonest on neck, head.
flight feather
the strong feathers on the wings and tail of birds used in flight. Called also remiges (plural), remex (singular).
feather follicle
a small tubular invagination of the skin with a fleshy dermal papilla at the bottom from which the feather grows. The papilla is inserted in the opening at the end of the quill.
feather mites
mites that live on and in feathers, often in enormous numbers but have little pathogenicity. Include the genera of Analges and Megninia of the family Analgesidae and the genus Dermoglyphus of the family Dermoglyphidae. Other miscellaneous genera are Syringophilus, Falculifer, Freyana, Pterolichus, Pteronyssus.
feather muscles
similar to erector pili muscles of mammals; attached to the sides of the follicle; capable of elevating or lowering entire groups of feathers.
feather picking
a vice thought to be due to insecurity and manifested by the bird pecking off its own feathers. If blood is drawn cannibalism may develop.
primary feather
flight feathers on the wings of birds.
psittacine beak and feather disease

feather pulling
see feather picking (above).
feather pulp
remnants of vascular tissue contained in the core of each feather.
saddle feather
the plumage covering the back of male birds.
feather syndrome
see psittacine beak and feather disease.
feather tract
area of the skin of a bird in which feathers grow. They are well defined and separated by unfeathered areas called apteria.

In the last seven years, the sheriff has increased his executive staff by nearly 50 percent," Remige said.
Remige also said he blames the Board of Supervisors' decision to cut $200 million from the department's budget in the past three years for the understaffing, which he said has contributed to eight inmate murders in two years at Men's Central Jail.
Remige noted that 76 percent of Los Angeles Police Department cars are staffed by two officers while only 24 percent of sheriff's cars have two deputies.
which depart colonies at approximately 20 d of age, accompanied by single chicks, and soon molt remiges synchronously, which renders them temporarily flightless (Gaston 1982; Scott 1990).
We determined age class by comparing pigmentation patterns of the two outermost primaries (9 and 10) to adjacent remiges.
De cada uno de los individuos se recolectaron remiges primarias y rectrices, que se almacenaron en tubos Eppendorf de 1,5 ml con 0,5 ml de etanol al 70%, para la posterior obtencion del ADN (DONOHUE & DUFTY, 2006; CONSTANTINI et al.

Field identification was based on presence of black patches in the auriculars, dark bill, gray remiges, tail slightly bifurcated, and pale red feet (Sibley, 2003).
Sed licet uariis malis numen Arcadis alitis obsitum miserans ducem peste soluerit hospitis, iam tamen mala remiges ore pocula traxerant, iam sues Cerealia glande pabula uerterant et nihil manet integrum uoce, corpore perditis.
The wing feathers are rectrices and the tail feathers are remiges (Figure 14-8).
A bird's flight feathers are comprised of the wing and tail feathers, technically known as remiges and rectrices.
Hinc disiuncta classis, turbati remiges, ablata cum malis vela, et semoti ab officiis naute; nec mora illidi naves invicem, undis concuti vel assummi, scopulis infringi, atque quo magis poterat ventorum impetus vehi cepere; quam ob rem in incertum cursum tenuere plurime.
