  Species - Facts, Information, and Encyclopedia Reference article
Because they do not crossbreed, it is safe to assume that there is a mechanism, often behavioral, that is preventing gene flow between the populations, and that therefore they should be classified as separate species.
For example, the Koalas of northern Australia are clearly smaller and lighter in colour than those of the south, but there is no particular dividing line: the further south an individual Koala is found, the larger and darker it is likely to be; Koalas in intermediate regions are intermediate in weight and colour.
The variation in Koalas is clinal (a smooth transition from north to south, with populations in any given small area having a uniform appearance), but the variation in magpies is not clinal.

It is thought to have descended from the St.
John's Water Dog (no longer in existence), a crossbreed of native water dogs and the Newfoundland to which the Labrador is closely related.
The name Labrador was given to this dog by the Earl of Malmesbury and other breeders in England in order to differentiate them from the Newfoundland dog.

Missing Links Primate Center: Oliver offers a photo and brief description of Oliver.
Oliver by John J. Ely reports on a cytogenetic analysis of this famous chimpanzee whose bipedal locomotion and shaved head have been presented as evidence that Oliver was a mutant or human/chimpanzee crossbreed.
The genetic testing indicates that "Oliver is a member of the Pan troglodytes troglodytes subspecies from Central Africa, has 48 normal Chimpanzee chromosomes, and was probably trapped in Gabon."
