||Male 65-70 cm, female 58-59 cm. Typical tragopan with distinctive, greyish lower breast and belly. Similar spp. Male differs from other tragopans by having a grey belly patch and, typically, yellow facial skin, although some males have been noted to have orange or red facial skin, perhaps owing to season and/or breeding condition, and possibly varying between subspecies. Female can be confused with Satyr Tragopan T. satyra and Temminck's Tragopan T. temminckii, but differs from both by yellowish eye-ring and paler, greyer belly, additionally from latter by less distinct pale spots and streaks on underparts. Juvenile initially like female, male gradually attains orange-red on neck during first year. Voice Male territorial call is loud, moaning ohh ohhah ohaah ohaaah ohaaaha ohaaaha ohaaaha.

This species qualifies as Vulnerable because its total population is believed to be small, declining and scattered in small subpopulations within a severely fragmented range. Widespread high levels of hunting and continuing habitat destruction will inevitably exacerbate this situation.

|Range Description:||Tragopan blythii occurs from Bhutan, through Arunachal Pradesh, Nagaland, Mizoram and Manipur in north-east India, and north Myanmar, to south-east Tibet and north-west Yunnan, China (BirdLife International 2001). It has not been recorded since the early 1970s in Bhutan (S. Sherub in litt. 2012). Recent information suggests it is rare in most of India, though locally common at a few sites in Nagaland and Arunachal Pradesh (A. Rahmani in litt. 2012). It is uncommon or rare in the Chin Hills-Mt Victoria region of west Myanmar (T. Htin Hla in litt. 2007), where although it may have declined good evidence is lacking (J. C. Eames in litt. 2004). It is also locally uncommon on Mt Majed and Mt Emawbon in eastern Kachin State, Myanmar (T. Htin Hla in litt. 2007). Call counts detected 14 pairs in the 50 km2 Blue Mountain National Park, Mizoram. |

|Population:||The population is estimated to number 2,500-9,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.|
Trend Justification: The species is suspected to be declining at a moderate rate, owing to widespread forest clearance, as well as hunting pressure in parts of its range.

Conservation Actions Underway
CITES Appendix I. The species is legally protected in all countries. It occurs in several protected areas, including: two small wildlife sanctuaries and a community reserve in Nagaland; the Blue Mountain National Park in Mizoram; Mouling National Park (A. Choudhury in litt. 2004), Sessa Orchid Sanctuary (Choudhury 2003), and Eaglenest Mehao and Dibang wildlife sanctuaries in Arunachal Pradesh; Thrumsing La National Park in Bhutan; Gaoligongshan National Park in China (Han Lianxian in litt. 2004), and Natma Taung National Park in Myanmar. Surveys for the species have been conducted in many areas in north-east India. An international studbook exists documenting the captive population held at locations in North America and Europe; however, recent analysis found the captive population is declining, ageing and highly inbred and requires new founders if it is not to be lost as a conservation resource for the species (St Jalme and Chavanne 2005). Work has since begun to move all of the captive birds in Europe to one location, and plans were in place to exchange birds between Europe and North America in an effort to introduce new blood lines to both populations (Jacken 2009). Conservation Actions Proposed
Design and implement monitoring projects in Nagaland, Manipur and Mizoram. Initiate a conservation awareness programme with communities in range areas, focusing on the effects of over-exploitation, and encourage local tourism initiatives. Continue (or initiate) surveys to establish its distribution, status and habitat requirements in Myanmar, Arunachal Pradesh, Bhutan, Yunnan and south-east Tibet. Use modern methods to study its ecology. Research the taxonomic status of the separate populations. Review the adequacy of the current protected areas system, to evaluate whether new areas in Myanmar, north-east India and south-east Tibet could be feasibly and usefully protected. Promote the careful management of existing captive populations and introduce new founders. Enforce laws preventing poaching and trade of the species (A. Rahmani in litt. 2012).
