Taxonomy
editThe red-billed blue magpie was described by French polymathGeorges-Louis Leclerc, Comte de Buffonin 1775 in hisHistoire Naturelle des Oiseaux.[3]The bird was also illustrated in a hand-coloured plate engraved byFrançois-Nicolas Martinetin thePlanches Enluminées D'Histoire Naturellewhich was produced under the supervision ofEdme-Louis Daubentonto accompany Buffon's text.[4]Neither the plate caption nor Buffon's description included a scientific name, but in 1783, Dutch naturalistPieter Boddaertcoined thebinomial nameCorvus erythrorynchusin his catalogue of thePlanches Enluminées.[5]The specimen described by Buffon had come from China, but thetype locationwas restricted to Canton by Hugh Birckhead in 1937.[6]The red-billed blue magpie is now one of five species placed in thegenusUrocissathat was introduced by German ornithologistJean Cabanisin 1850.[7][8]The name of the genus combines theAncient Greekourameaning "tail" andkissameaning "magpie". The specific epitheterythrorynchacombines the Ancient Greekeruthrosmeaning "red" andrhunkhosmeaning "bill".[9]

Description
editThe head, neck, and breast are black with a bluish spotting on the crown. The shoulders and rump are a duller violet-blue, and the underparts are a greyish cream. The long tail is a brighter violet-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 each eye. This red can vary across its range to almost yellow in some birds.
Habits and habitat
editThe red-billed blue magpie occurs in a broad swath from the northern parts of theIndian subcontinent,and further eastwards. It ranges from the westernHimalayaseastwards intoMyanmar,Thailand,Cambodia,Laos,andVietnam,and through central and easternChinato southwestManchuria,in evergreen forest and scrub in predominantly hilly or mountainous country. It has adapted to urban habitat, and can be seen in large cities in China such as Beijing and Hong Kong. They nest in trees and large shrubs in a relatively shallow nest. Usually, three to five eggs are laid.
Food is sought both in trees and on the ground. It takes the usual wide range of food, such as invertebrates, other small animals, and fruit and some seeds. It robs nests of eggs and also chicks. Vocal mimicry is very apparent in this species, and its calls are very varied, but the most usual are a grating rattle and a high-pitched whistle somewhat like a flute.
