Species
A population whose members breed among themselves but not (normally) with members of other similarly defined populations. The members of a particular species are said to be 'conspecific'. The species is the only division used in taxonomy which is actually defined in nature. Each species has been given a scientific name which consists of two parts, under the system of binomial nomenclature, the actual 'specific name' being the second of the two. Closely related species are placed in the same genus and most species are divided into subspecies.From Peter Weaver's Birdwatcher's Dictionary
