Blood pheasant

The blood pheasant (Ithaginis cruentus) is the only species in genus Ithaginis of the pheasant family. It is a relatively small, short-tailed pheasant that is widespread and is fairly common in eastern Himalayas, ranging across India, Nepal, Bhutan, China and northern Myanmar. Since the trend of the population appears to be slowly decreasing, the species has been evaluated as Least Concern by IUCN in 2009.[1]

The blood pheasant was the national bird of the former Kingdom of Sikkim,[2] and remains Sikkim's state bird.[3]

Description

Blood pheasants have the size of a small fowl, about 17 in (43 cm) in length with a short convex, very strong black bill, feathered between bill and eye, and a small crest of various coloured feathers. The colour of the plumage above is dark ash, with white shafts, the coverts of the wings various tinged with green, with broad strokes of white through the length of each feather, the feathers of the chin deep crimson; on the breast, belly and sides feathers are lance-shaped, of various length, the tips green with crimson margins, collectively resembling dashes of blood scattered on the breast and belly. The tail consists of twelve sub-equal feathers, shafts white, rounded, the ends whitish, the coverts a rich crimson red.[4]

Both males and females have red feet and a distinct ring of bare skin around the eye that typically is crimson colored, but is orange in a few subspecies. Females are more uniformly colored, being overall dull brown and often with some gray to the nape. Although some of the subspecies that have been described are highly distinctive, others are not, and some variation appears to be clinal. Consequently, the number of valid subspecies is disputed, with various authorities recognizing between 11 and 15. They mainly vary in the plumage of the males, especially the amount of red or black to the throat, forehead, neck, chest and tail, and the presence or absence of rufous in the wings.[5]

Distribution and habitat

Blood pheasants live in the mountains of Nepal, Sikkim, northern Myanmar, Tibet, and central and south-central China, where they prefer coniferous or mixed forests and scrub areas near the snowline. They move their range depending on the seasons, and are found at higher elevations during the summer. With snow increasing in fall and winter they move to lower elevations.[5]

gollark: What's this in response to?
gollark: So my search thing seems to be handling the tens of megabytes of slowly downloading esolangs.org data somewhat well, in that queries which don't have any results in it run fine. On the other hand, I didn't add any pagination and it would be quite hard to given how the search algorithm works, so looking for stuff like "the" is slow. And the search algorithm is terrible at looking up specific phrases.
gollark: Just text, formatting and a little metadata (in some insane XML format) - no images, talk pages, user pages, that sort of thing.
gollark: This is without images and whatnot.
gollark: Wikipedia is "only" 15GB compressed, but the inverted index data structure this uses for search is biiiiig.
