Site description Dum Duma (2,880 ha), Dangori (920 ha) and Kumsong (2,250 ha), these three reserve forests in Tinsukia district, in eastern Assam constitute the IBA. The forests of all areas are Tropical Evergreen Rainforest types dominated by Dipterocarpus macrocarpus (Hollong) on flat plains. All these areas are surrounded by tea gardens and human settlements. These forests are known for their populations of White-winged Duck Cairina scutulata, but are also important for other wildlife, especially primates. The largest confirmed gathering of the White-winged Duck in the world was recorded in Dangori RF, where 14 were seen roosting at one site in 1995 (Choudhury 1996, 1998). The vegetation type of the sites is mainly Tropical Evergreen Rainforest, dominated by Dipterocarpus macrocarpus, Shorea assamica, Mesua ferrea, Terminalia myriocarpa, Artocarpus chaplasha, Dillenia indica, Anthocephalus cadamba, Bombax ceiba and Ficus spp. There are many jungle pools or ponds in these areas, which are the major haunts of the White-winged Duck.
AVIFAUNA: The site is important for rainforest birds. More than 100 species have been recorded but more are likely to occur (A. U. Choudhury pers. comm. 2002). The White-winged Duck and Brown Hornbill Anorrhinus tickelli are noteworthy species while there are reports of the Masked Finfoot Heliopais personata from Dum Duma RF (Choudhury 1997). Sino-Himalayan Subtropical Forest species (Biome-8) such as Blue-throated Barbet Megalaima asiatica, Bay Woodpecker Blythipicus pyrrhotis, White-throated Bulbul Alophoixus flaveolus, Black-winged Cuckoo-shrike Coracina melaschistos and Nepal Fulvetta Alcippe nipalensis are commonly seen. This site has been selected as an IBA as it is one of the most important areas for the long-term protection of the globally Endangered White-winged Duck.
OTHER KEY FAUNA: Leopard Panthera pardus, Hoolock Gibbon Hylobates hoolock, Capped Langur Trachypithecus pileatus, Rhesus Macaque Macaca mulatta, Pig-tailed Macaque M. nemestrina, Slow Loris Nycticebus coucang, Malayan Giant Squirrel Ratufa bicolor, Common Giant Flying Squirrel Petaurista petaurista, Barking Deer or muntjak Muntiacus muntjak and a small herd of Wild Water Buffalo Bubalus arnee (= bubalis). The Wild Elephant Elephas maximus and Tiger Panthera tigris are no longer found here.
