A dove is a bird, also known as a pigeon, although certain species are more often referred to as doves. For example, a white pigeon is usually called a dove.
The terms dove and pigeon are interchangeable in their Biblical references. There are four species of doves that inhabited the Holy Land in Bible times. The most common is Columba livia or the Rock Pigeon. Also, a common variation is turtle-dove, which is a term that may be derived from the notes of its call. The most comon turtle-dove in Bible times was likely the Turtur aruitus
