If a pigeon has a checker pattern on its wings it is called a checker. Checkers can range from very light gray with only a few black checks, to very dark with only a little light-gray still showing. If a bird is totally black or dark gray, it is called a spread. To remember this term, it helps to think that the dark color has spread over the bird's entire body. These birds are solid white .
Some white pigeons are albinos, with pink eyes and legs.
These are called pieds. Pied birds come in two forms. One type looks like it has been splashed with white. The other type has white only on the primary wing feathers. Sometimes the white flight feathers are hard to see when the bird is on the ground, but, when the bird flies, the white is obvious.
