Justification
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Blood Pheasant

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

Description[edit]

IthaginisCruentusWolf.jpg

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.[2]

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.[3]

Taxonomy[edit]

Subspecies[edit]

There are twelve recognized subspecies:

  • I. c. affinis (CW Beebe, 1912) - Sikkim region in India
  • I. c. beicki (Mayr and Birckhead, 1937) - Beick's Blood Pheasant - north central China
  • I. c. berezowskii (Bianchi, 1903) - Berezovski's Blood Pheasant - mountains of central China
  • I. c. clarkei (Rothschild, 1920) - Clarke's Blood Pheasant - southwest China
  • I. c. cruentus (Hardwicke, 1821) - Himalayan Blood Pheasant - northern Nepal to northwestern Bhutan
  • I. c. geoffroyi (Verreaux, 1867) - Geoffroy's Blood Pheasant - western China and southeast Tibet
  • I. c. kuseri (Beebe, 1912) - Kuser's Blood Pheasant - upper Assam in India and southeast Tibet
  • I. c. marionae (Mayr, 1941) - Mrs. Vernay's Blood Pheasant - mountains of southwest China and northeast Myanmar
  • I. c. michaelis (Bianchi, 1903) - Bianchi's Blood Pheasant - north central China
  • I. c. rocki (Riley, 1925) - Rock's Blood Pheasant - southwestern China
  • I. c. sinensis (David, 1873) - David's Blood Pheasant - central China
  • I. c. tibetanus (ECS Baker, 1914) - Tibetan Blood Pheasant - eastern Bhutan and southern Tibet

Distribution and habitat[edit]

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.[3]

Cultural depictions[edit]

The Blood Pheasant is the state bird of the Indian state of Sikkim.
