The bird genus Columba comprises a group of medium to large pigeons. The terms "dove" and "pigeon" are used indiscriminately for smaller and larger Columbidae, respectively. Columba species – at least those of Columba sensu stricto – are generally termed "pigeons", and in many cases wood-pigeons. The rock dove has given rise to the majority of domesticated pigeon breeds, such as the racing pigeon and the fantail pigeon, some of which have become feral. Meanwhile, "wood pigeon" by itself usually means the common wood pigeon.

The rock dove, rock pigeon, or common pigeon is a member of the bird family Columbidae. In common usage, it is often simply referred to as the "pigeon", although this is the wild form of the bird; the pigeons most familiar to people are the domesticated form of the wild rock dove.
