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).
Blyth’s Tragopan (Tragopan blythii) or the Grey-bellied Tragopan is a pheasant that is a vulnerable species. The common name commemorates Edward Blyth (1810–1873), English zoologist and Curator of the Museum of the Asiatic Society of Bengal.
Distribution and Population
The animal’s population is small and is believed to be decreasing at a rapid rate. Blyth’s Tragopan is located in many different areas, including Bhutan through north-east India, north Myanmar to south-east Tibet, and also China. The total population is estimated to be about 2,500 to 9,999 birds. This estimate is a very small number compared to some of its relative birds. Tragopan blythii normally flocks to wooded areas as it prefers the undergrowth of evergreen oak and rhododendron forests, and other dark, quiet places. This bird has a higher elevation than most birds.
There are two recognized subspecies:
- T. b. blythii (Jerdon, 1870) - nominate - Himalayas of northeast India to southwest China and northern Myanmar
- T. b. molesworthi (ECS Baker, 1914, ) - Molesworth's Tragopan - eastern Bhutan
Blyth’s Tragopan pheasant is the largest of the genus Tragopan. Like most pheasants, the male is brightly colored. It is recognized by its rusty red head, yellow facial skin, and that it is spotted with small white dots on its back called ocelli. A black band extends from the base of the bill to the crown coupled with another black band extending behind the eyes. Like the rest of the tragopans, males have two pale blue horns that become erect during matting. Its lappet, a decorated flap, hangs from the throat and is brightly colored. This lappet can be expanded and exposed during mating season as well. Females are not as brightly colored as the male tragopan, for they do not need the extravagant appearance to attract a male counterpart. Overall, they are dark brown with a mixture of black, buff and white mottling. Their simple and dull look is a protection mechanism from other animals, known as camouflage. It also allows the females to protect their young that are in the early stages of life.
Blyth’s Tragopan are generalists. In the wild, they consume seeds, berries, fruits, and buds. Captive birds usually consume insects, worms, and even small frogs. While they are primarily vegetarians, most birds have a predilection for berries and fruit.
The bird primarily moves up and down the slopes in search for food. It is, however, uncommon for this species to travel far, due to the change in climate from area to area. This is a result of the mild winters in their habitat, which are tolerable for longer periods of time. For the majority of the species, travel is only necessary in attempting to avoid the drying out of their vegetation. In this case, they may move down mountain sides for more comfortable living conditions and a readier food supply. There is little information or support on how the Blyth’s Tragopan moves, but it is suggested that they travel together in groups of four to five, much like other species of tragopans.
Blyth’s Tragopan starts mating in April and continues well into May. The males advertise themselves with flamboyant displays to attract females.
Mating display may involve bowing and scraping the ground with their wings slightly raised and their flesh horns fully dilated while projected forward. The more flamboyant and extravagant the male acts, the more likely they are to attract a female. If the female does not respond, the male intensifies this wild behavior to draw more attention to him. The male then proceeds to strut around the female, in an attempt to distract the female. He then continues the movements with his breast pushed forward and his wings extended into the air.
Growth and Development
After a female becomes impregnated she can lay up to two to five eggs. The incubation period for eggs lasts for about twenty-eight days. After hatching, the offspring has a similar appearance to the female hen. The male tragopans acquire red on their neck during the first spring moult. During the second year of life, full adult plumage is attained in the tragopan.
While no nests have been found in the wild, the natives of Nagaland have stated that the nests are never on the ground, but are found in trees, stumps, and small bushes. This record is consistent with the birds' desire to stay at high altitudes. The heights range from six to twenty feet above the ground. Nesting above the ground is advantageous because the seasonal rains are intensified to where flooding can sweep away all the vegetation that is found on the ground. The nests are made of sticks with a lining of smaller vegetation such as grass or weeds.
In north-east India, deforestation is a major factor in the decreasing population of T. blythii, as the forests are the main source of food. By removing this source, the pheasants are left with little or no food to consume. In addition, its primary habitat is in the forest.
Overexploitation is one of the biggest threats to all birds including Blyth’s Tragopan. Twelve percent of bird species are threatened to extinction and overexploitation. Blyth’s Tragopans are considered to be the main threat to thirty seven percent of that number. Overexploitation reduces the population of the species and causes the listing of eleven percent of the threatened birds on the IUCN Red List. The biggest concern is the eleven critically endangered species for which overexploitation is believed to be the factor that the population numbers are declining.
In Nagaland and Arunachal Pradesh, the pheasant is being hunted for food with large-scale snaring and are also regularly shot with guns and slingshots.According to the local tribes of eastern Nagaland the bird has become locally extinct in many of their forests where it was found commonly. The major reason for decline in population in Nagaland is over hunting.
High levels of grazing and slash and burn agriculture in Bhutan are also significant threats. The effect of slash and burn techniques has a significant effect on the species because it takes away the entire habitat that the bird has. The population of the tragopan is believed to be declining because of these threats which are also dividing up the populations into smaller subpopulations due to fragmentation.
Fragmentation is an issue because it divides larger populations into smaller ones over a large area. The tragopans are not able to go from one area to the other because there are normally great distances between these populations. Fragmentation also does not let the pheasants get the genetic variation that they need. In order for them not to have problems with the hatchlings they need to have a diversity of different species.
There is already some habitat set aside for the T. blythii to survive. These areas include two wildlife sanctuaries and a small reserve in Nagaland, along with some other small areas for the bird to survive.
This species is legally protected in all countries in which it is found. Conservation awareness plans need to be implemented in all areas and more people to enforce the laws that are already set in place. With these small sub communities, which are scattered over the habitat areas of the pheasant, it is becoming more and more difficult for the birds to reproduce with the genetic differences they need to survive.
The Blue Mountain National park in Mizoram, India is currently taking surveys of how many different Blyth’s Tragopan can be heard and seen in the area. The population was considered to be about 500 and 5000. The continuing monetization for the Blyth’s Tragopan is essential for the conservation management aspect of the pheasant. Together with Blue Mountain and the organization proposal there will be a way to help the Blyth’s Tragopan.
