Brief Summary

provided by EOL authors
Green magpies are a beautiful mid-sized songbird in the family Corvidae. The striking emerald green coloration of most of its body plumage is the result of yellow carotenoid pigments from dietary sources combined with the blue that is due to structural arrangement of the keratin in its feathers. Over time, in life and in museum drawers, the yellow pigment fades or wears away. Thus older feathers look turquoise blue. These birds have a bright orange-red bill, somewhat heavier than other corvids, and a strong black facial mask. Flight feathers are chestnut with faint barring. Bold white tips on black feathers decorate the tertiaries and underside of the tail. Green magpies are native to southeast Asia.

Feather coloration

provided by EOL authors
A cross section of the rami from head feathers in this species (Hudon 2005) shows a basal layer of dark melanin around the medulla, surrounded by a wider layer (described as a "homogenous cloudy cell"). Interference of light through this cloudy layer, when backed by the dark pigment, results in the blue that we can see. When feathers are green, they have a thin layer of yellow pigment in the cortex outside of the cloudy cell layer. Blue feathers lack pigment in the cortex layer. Authors have suggested that the yellow pigment wears away, so that the bird turns blue over time. Why are other green birds not prone to this color change? Perhaps the layer of pigment is particularly thin in Cissa species or perhaps there is some other reason why the pigment is more easily lost.

Common green magpie

provided by wikipedia EN

The common green magpie (Cissa chinensis) is a member of the crow family, roughly about the size of the Eurasian jay or slightly smaller. In the wild specimens are usually a bright green colour (often fades to turquoise in captivity or with poor diet as the pigment is carotenoid based[2]), slightly lighter on the underside and has a thick black stripe from the bill (through the eyes) to the nape. Compared to the other members of its genus, the white-tipped tail is quite long. This all contrasts vividly with the red fleshy eye rims, bill and legs. The wings are reddish maroon.

It is found from the lower Himalayas in north eastern India in a broad south easterly band down into central Thailand, Malaysia, Sumatra and northwestern Borneo in evergreen forest (including bamboo forest), clearings and scrub.

This bird seeks food both on the ground and in trees, and takes a very high percentage of animal prey from countless invertebrates, small reptiles, mammals and young birds and eggs. It will also take flesh from a recently killed carcass.

The nest is built in trees, large shrubs and often in tangles of various climbing vines. There are usually 4–6 eggs laid.

The voice is quite varied but often a harsh peep-peep. It also frequently whistles and chatters.

Taxonomy

In bluish plumage due to lack of lutein, Kaeng Krachan National Park, Thailand

The common green magpie was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1775 in his Histoire Naturelle des Oiseaux.[3] The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text.[4] Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Coracias chinensis in his catalogue of the Planches Enluminées.[5] Buffon believed that his specimen had come from China but the species only occurs in the extreme south of the country. The type locality was redesignated in 1952 by the German ornithologist Erwin Stresemann as Mergui, Tanintharyi Region, Myanmar.[6]

The common green magpie is now one of four species that are placed in the genus Cissa that was introduced by the German zoologist Friedrich Boie in 1826 with the common green magpie as the type species.[7][8] The generic name is from the Ancient Greek kissa meaning a "jay" or "magpie". The specific epithet chinensis was chosen by Boddaert in the mistaken belief that the specimen illustrated by Martinet had come from China.[9]

Five subspecies are recognised:[8]

  • C. c. chinensis (Boddaert, 1783) – Himalayas to south China, north Indochina, Thailand and Myanmar
  • C. c. klossi Delacour & Jabouille, 1924 – central Indochina
  • C. c. margaritae Robinson & Kloss, 1919 – Lang Bian Mountains (south Vietnam)
  • C. c. robinsoni Ogilvie-Grant, 1906 – Malay Peninsula
  • C. c. minor Cabanis, 1850 – Sumatra and Borneo
