Pigeons and doves constitute the bird family Columbidae within the order Columbiformes, which include some 300 species of near passerines. In general speaking 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 terms "dove" and "pigeon." This family occurs worldwide, but the greatest variety is in the Indomalaya and Australasia ecozones. Young doves and pigeons are called "squabs".
The Rock Pigeon (Columba livia), or Rock Dove, illustrated on top right, is a member of the bird family Columbidae (doves and pigeons).In common usage, this bird is often simply referred to as the "pigeon". The species includes the domestic pigeon (including the fancy pigeon), and escaped domestic pigeons have given rise to feral populations around the world.
The House Sparrow (Passer domesticus) illustrated in the lower right corner, is a species of passerine bird of thesparrow family Passeridae. It occurs naturally in most of Europe, the Mediterranean region, and much of Asia. It has also been intentionally or accidentally introduced to many parts of the world, making it the most widely distributed wild bird. It is strongly associated with human habitations, but it is not the only sparrow species found near houses. It is a small bird, with feathers mostly different shades of brown and grey.
The maxicards and FDC are also lovely:
