The primary flight feathers of the wings and the main covert feathers are dark blue.

There also are minor covert feathers overlying the flight feathers.

He wore armour - brass scale lorica made to look like covert feathers - over his chest and down strong arms to the elbow.

The upper surface of the wings has barring formed by the covert feathers and their paler fringes.

It also has buff edges to all the upper part and wing covert feathers, while the plumage below is broadly edged greyish-white.

It has a blue eye mask, separated from the crown by a white line, and a pale lilac ruff of long stiffened ear covert feathers.

The chances of surviving that move were slim-he'd gambled on his swiftness, and the makaar did no more damage than removing a few covert feathers.

Largely hidden when the wings are folded, this bright coloring covers most of the covert feathers, and the basal half of the primaries and secondaries.

Young Varied Thrushes are generally brown, though its stomach feathers are white, and initially harbors two orange stripes at the covert feathers.

Young birds have the brown tips to the black head feathers, a sandier brown back, and pale fringes to the upperpart and wing covert feathers.

The peacock tail ("train") is not the tail quill feathers but the highly elongated upper tail covert feathers.

Young birds have the white areas of plumage tinged with grey, a less distinct breast band, and pale fringes to the upperpart and wing covert feathers.

In these birds, the fifth set of secondary covert feathers does not cover any remex, possibly due to a twisting of the feather papillae during embryonic development.

A covert feather or tectrix on a bird is one of a set of feathers, called coverts (or tectrices), which as the name implies, cover other feathers.

Covert feathers are preserved covering the upper part of the wing feathers in some specimens, and some specimens have preserved the contour feathers of the body.

The under-tail covert feathers (short feathers under the base of the main tail feathers) are generally mostly yellow in the male and generally mostly green in the female.

The adult's plumage is a dark sooty olive above and grayish brown below, with a slightly paler rump and uppertail covert feathers, and a significantly paler throat.

A similar effect in the wing covert feathers imparts a more uniform yellow colouration to the clear parts of the wing, which in consequence entirely lack the ghost markings visible in the Lutino.

The male peacock is predominantly blue with a fan-like crest of spatula-tipped wire-like feathers and is best known for the long train made up of elongated upper-tail covert feathers which bear colourful eyespots.

The 'pin feather' of the Eurasian Woodcock (the covert feather of the outermost primary) can be used as a fine paintbrush for miniatures, or as a delicate tool for moving tiny objects (e.g. specks of dust).

The pencil sketch depicts the crest as a tuft of rounded feathers attached to the front of the head at the base of the beak, and shows long primary covert feathers, large secondary feathers, and a slightly bifurcated tail.

Peafowl are two Asiatic and one African species of flying bird in the genus Pavo of the pheasant family, Phasianidae, best known for the male's extravagant eye-spotted tail covert feathers, which it displays as part of courtship.

It also has prominent double wing bars formed by yellowish-white tips to the wing covert feathers (a long bar on the greater coverts and a short bar on the median coverts), yellow-margined tertial feathers, and long yellow supercilium.

By analogy, if peacock 'tails' (large tail covert feathers) act as a handicapping system, and a peahen knew nothing about two peacocks but the sizes of their tails, she could "infer" that the peacock with the bigger tail has greater unobservable intrinsic quality.

As the feather bears little resemblance to the retrices of the other full Archaeopteryx skeletons, it is generally thought to be a wing feather: Griffiths and others have concluded it was a remex, while Carney in 2012 interpreted it to be a covert feather.
