blackfeathered
Blackfeathered is a term that describes an organism, typically a bird, possessing feathers that are entirely or predominantly black in color. This coloration can be a result of genetic mutations, melanin pigment concentration, or a combination of both. In many bird species, black plumage serves various purposes including camouflage, thermoregulation, and mate attraction. For instance, in some species, black feathers absorb more sunlight, aiding in heat absorption in colder climates. Conversely, in extremely hot environments, the light-absorbing properties might be a disadvantage, and some black-feathered birds may have adaptations to mitigate overheating.
The genetic basis for black plumage varies. In some cases, it is controlled by a single gene
Blackfeathered individuals can be found across a wide range of bird families and species. Examples include
