Azure-winged Magpie in Wings of Asia
The Azure-winged Magpie (Cyanopica cyana) has a long light-blue tail and wings, a grey back, white throat and a black cap on the top of its head. European birds are distinguished from Asian birds by their lack of a pale blue tail spot and much smaller size. This species of magpie travel together in groups up to 30 large. They also nest and forest together. The Azure-winged Magpie appears to be relatively intelligent having a complex system of calls and are able to detect any foreign eggs in their nests and weed them out (such as those from cuckoos, well known for this old trick). This species is found in the wild in Spain, Portugal and the Far East (China, Korea and Japan), but it is not found anywhere in between. How could this happen? Perhaps magpies lived all over Europe and Asia and died out over time, leaving only these two separated populations today; however, DNA analysis now suggests that these two subspecies are in fact separate species.
