The Red-billed Blue Magpie, Urocissa erythrorhyncha is a species of bird in the crow family Corvidae. It is about the same size as the European Magpie but has a much longer tail, the longest tail of any corvid.
The head, neck and breast are black with a bluish spotting on the crown. The shoulders and rump are a duller blue and the underparts are a greyish cream. The long tail is a brighter blue (as are the wing primaries) with a broad white tip. The bill is a bright orange-red as are the legs and feet and a ring around the eye. This red can vary across its range to almost yellow in some birds.
