Carrier Pigeon Blue

Homing pigeon

The homing pigeon is a variety of domestic pigeon, selectively bred for its ability to find its way home over extremely long distances. Because of this skill, homing pigeons were used to carry messages, a practice referred to as "pigeon post." Until the introduction of telephones, they were used commercially to deliver communication; when used during wars, they were called "war pigeons."

Columbidae

Columbidae is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with small heads, relatively short necks and slender bills that in some species feature fleshy ceres. They feed largely on plant matter, feeding on seeds (granivory), fruit (frugivory), and foliage (folivory).

Blue

Blue is one of the three primary colours in the RGB (additive) colour model, as well as in the RYB colour model. It lies between violet and cyan on the spectrum of visible light. The term blue generally describes colours perceived by humans observing light with a dominant wavelength between approximately 450 and 495 nanometres. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.
