When Bird Become Agressive……… Pigeons and doves comprise the family Columbidae within the order Columbiformes, which include some 300 species of near passerine birds. In general parlance the terms “dove” and “pigeon” are used somewhat interchangeably. In ornithological practice, there is a tendency for “dove” to be used for smaller species and “pigeon” for larger ones, but this is in no way consistently applied, and historically the common names for these birds involve a great deal of variation between the term “dove” and “pigeon.”The species commonly referred to just as the “pigeon” is the feral Rock Pigeon, common in many cities.Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere.
