Plumage (from Latin pluma 'feather') is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes.
If a bird produces a third plumage in addition to the basic and alternative, it is known as supplemental plumage. This plumage is most frequently found in ptarmigans. The unique plumage of a juvenile bird is known as juvenal (or less precisely, juvenile) plumage. [2] When the bird is molting, the molt is known as a prejuvenal, prebasic ...
Plumage is regularly moulted; the standard plumage of a bird that has moulted after breeding is known as the "non-breeding" plumage, or—in the Humphrey–Parkes terminology—"basic" plumage; breeding plumages or variations of the basic plumage are known under the Humphrey–Parkes system as "alternate" plumages.

Plumage and body parts of birds-of-paradise glow in certain areas when viewed under blue and ultraviolet, or UV, light, appearing bright green or yellow-green, scientists reported in a new study ...
The plumage is gray above with a white rump, and white below with a distinct white area above the lores and a narrow whitish eye ring giving the bird a spectacled appearance. The underparts are white. In breeding plumage, the bird shows brown barring on the upperparts. Non-breeding birds are plainer.
This pattern is similar to the coloration of many extant bird species, which use plumage coloration for display and communication, including sexual selection and camouflage. It is likely that non-avian dinosaur species utilized plumage patterns for similar functions as modern birds before the origin of flight.
The plumage is thick, providing insulation in the bird's cold native habitat. [21] Like most corvids, Canada jays are not sexually dimorphic, but males are slightly larger than females. Juveniles are initially coloured very dark grey all over, gaining adult plumage after a first moult in July or August. [22]
The photographer had captured a rapid-fire sequence of more than 60 images, seven of which showed the huge bird formation. Yet there was one that stood out from the rest.
