AVIFAUNA: Namdapha-Kamlang is one of the most biologically diverse IBAs in India. Its avifauna is a unique blend of four biomes (Sino-Himalayan Temperate, Sino-Himalayan Subtropical, Indo-Chinese Tropical Moist Forests and Eurasian High Montane). About 450 bird species have been reported from Namdapha Tiger Reserve, including several globally threatened and Restricted Range species (Katti et al. 1992, Athreya et al. 1997, Singh 1999).
The Endangered White-bellied Heron Ardea insignis is regularly seen in Deban and Noa-Dihing river (300-450 m). Solitary individuals have been sighted by Alstrom et al. (1994), Athreya et al. (1997) and Choudhury (2000).
The White-winged Duck Cairina scutulata has been reported from the lower reaches of Namdapha (Choudhury 1996). It has been seen at Ranijheel, Motijheel and Rajajheel (Choudhury 2002).
Stattersfield et al. (1998) have identified 21 Restricted Range species from the Eastern Himalaya. Till now, 11 of these species have been seen in Namdapha.
The Northeast is famous for its bird diversity and Namdapha-Kamlang IBA is one of the finest examples. Its thick forests contain 98 members of Family Muscicapidae (babblers, flycatchers, warblers and thrushes) (Athreya et al. 1997). Indeed, almost half the birds seen in Namdapha belonged to this family. Mixed hunting parties containing several hundred birds of over 20 species have been reported (Athreya et al. 1997).
In the Eastern Himalaya, particular bird species tend to be present at lower altitude than in the Western Himalaya. Namdapha is one of the easternmost regions of India and the bird sightings by Athreya et al. (1997) further confirm this trend. Over 10% of the birds recorded by them were at lower altitude or even below the lowest altitude record of the species in India.
Many northeastern birds, uncommon or rarely seen elsewhere, are fairly common in Namdapha. For example, Grey Peacock Pheasant Polyplectron bicalcaratum, Wreathed Hornbill Aceros undulatus, Blue-naped Pitta Pitta nipalensis, Collared Treepie Dendrocitta frontalis, Large Scimitar Babbler Pomatorhinus hypoleucos, Streaked Wren-Babbler Napothera brevicaudata, Eye-browed Wren-Babbler Napothera epilepidota, Rufous-vented Laughingthrush Garrulax gularis, White-hooded Babbler Gampsorhynchus rufulus, Rufous-throated Fulvetta Alcippe rufogularis, Rufous-backed Sibia Heterophasia annectans, Beautiful Sibia Heterophasia pulchella, Green Cochoa Cochoa viridis and Black-breasted Thrush Turdus dissimilis are fairly widespread in the Park, but not necessarily easy to locate (Kazmierczak and Singh 1998).
OTHER KEY FAUNA: Namdapha is famous for its felines - it harbours three large, two medium and many smaller cats. Tiger Panthera tigris and Leopard P. pardus are found at lower and mid elevation, while above 3,000 m, the Snow Leopard Uncia uncia is reported (unconfirmed). The rare Clouded Leopard Neofelis nebulosa is also found. Singh et al. (undated) have recorded 96 species of mammals. There are not many IBAs in India where so many mammals species are seen. Athreya et al. (1997) found six species of non-human primates, excluding Slow Loris Nycticebus coucang reported.
Recently, Captain (2000) reported 117 species snakes and three legless lizards within a 2½ month survey in Namdapha. Two of the snakes (Trimeresurus medoensus and Amphiesma venningi) are first records from India.
This large IBA is quite remote, largely inaccessible and uninhabited. Most of the forest is largely untouched. The abundance of forest resources around the area fulfils the needs of the people. However, Namdapha is now coming under increasing pressure due to encroachment on its eastern side. Insurgency is another big problem for the administration of the Park. Population pressure is increasing on the western boundary also, on the northern bank of Nao Dihing river where Chakma tribals have settled. On the eastern fringe, the Lisu tribe, a predominantly hunter-gatherer community, periodically enters the Park from settlements in Myanmar and exerts pressure.
