Eaglenest Wildlife Sanctuary is a protected area of India in the Himalayan foothills of West Kameng District, Arunachal Pradesh. It conjoins Sessa Orchid Sanctuary to the northeast and Pakke Tiger Reserve across the Kameng river to the east. Elevation ranges from . It is a part of the Kameng Elephant Reserve.
Eaglenest Wildlife Sanctuary derives its name from Red Eagle Division of the Indian army which was posted in the area in the 1950s.Athreya Ramana (2005). Kaati Trust, Pune Eaglenest Wildlife Sanctuary
Geography and climate Eaglenest and Sessa Orchid Sanctuary together occupy a rough east–west rectangle with Sessa occupying the northeast quadrant. Eaglenest is bounded to the north by Eaglenest Ridge and the reserved forests of the Bugun community (Lama Camp area). Eaglenest adjoins Tawang district to the north. The Bhalukpong–Bomdila highway (and Pakke immediately beyond) are its eastern boundary. There are no distinct geographical features delineating its western boundary along the Bhutan border and the southern boundary at about 27° N latitude.
Eaglenest and Sessa ridges rise to and respectively and are the first major barriers to the monsoon as it moves north from the plains of Assam. These ridges get over of rain on the southern slopes and about on the northern ones.Choudhury A.U. (2003). Birds of Eaglenest Wildlife Sanctuary and Sessa Orchid Sanctuary, Arunachal Pradesh, India. Forktail 19:1-13
The eastern half of Eaglenest and Sessa sanctuaries is drained by the Tippi Naala (Tippi river) which joins the Kameng river at Tippi village on the Bhalukpong–Bomdila highway. Several smaller streams including Buhiri Nadi and Dihung Nadi in the western half of the area flow down to join the Brahmaputra separately.Topographic mapArmy Map Service, Corps of Engineers (1955) Series U502, Sheet NG-46-2, Towang, India; Bhutan; China, topographic map 1:250,000, retrieved 10/2/2007 Topographic map
Eaglenest Wildlife Sanctuary is part of the Kameng protected area complex (KPAC), the largest contiguous closed-canopy forest tract of Arunachal Pradesh, which includes Eaglenest, Pakke, Sessa, Nameri, and Sonai Rupai sanctuaries and associated reserved forest blocks. The complex covers 3500 km2 in area and ranges from to in altitude.
Eaglenest has an unpaved road running from its base to Eaglenest pass at allowing good access to the entire altitudinal range, making it accessible to the military, scientists and ecotourists.Official website of West Kameng District (6/21/2007) Geography

Eaglenest is the site where Bugun liocichla was first discovered in 1995 and again observed and described in 2006 by Ramana Athreya.Athreya, R. (9/8/2006) A new species of Liocichla (Aves: Timaliidae) from Eaglenest Wildlife Sanctuary, Arunachal Pradesh, India Indian Birds 2 (4): pp. 82–94
Herpetofauna
Eaglenest Wildlife Sanctuary is home to a wide variety of herpetofauna including at least 34 species of amphibians, 24 species of snakes and 7 species of lizards including 3 geckos, 3 agamids and 4 skinks. Abor Hills agama was rediscovered at Eaglenest after 125 years. Other rare species include the Darjeeling false-wolfsnake which was only known to science through five specimens, Anderson's mountain lizard, Günther's kukri snake, common slug snake, and keelback snakes which have not been definitively identified.
Mammals Eaglenest Wildlife Sanctuary provides habitat to clouded leopard, marbled cat, Asian golden cat and leopard cat. Other mammal species include the endangered capped langur, red panda, Asiatic black bear and the vulnerable Arunachal macaque and gaur. It was here that a new taxon of primate was discovered in 1997 by noted primatologist of northeast India Dr Anwaruddin Choudhury, but he thought it to be a new subspecies of Tibetan or Pere David's macaque. It was described as a new species, i.e., Arunachal macaque in 2004. The highest elevation (11,000 ft) that the wild Asian elephants reach anywhere is partly in this sanctuary.Choudhury, A.U. (1999). Status and Conservation of the Asian elephant Elephas maximus in north-eastern India. Mammal Review 29(3): 141-173.
Butterflies
Eaglenest Wildlife Sanctuary is home to at least 165 species of butterflies including Bhutan glory, grey admiral, scarce red-forester, dusky labyrinth, tigerbrown, jungle-queen sp, white-edged bushbrown, and white owl.Athreya, R. (2006) Eaglenest Biodiversity Project − I (2003–2006): A report submitted to the Forest Department of the Government of Arunachal Pradesh, India, and the Rufford-Maurice-Laing Foundation (UK).

Flora
In Eaglenest Wildlife Sanctuary there is a camp named Sessni which in Nepali language means nettle. The place is filled with poisonous elephant nettles on either side of the road.
Conservation
Eaglenest Wildlife Sanctuary is physically protected from timber and animal poaching only by its isolation and the poor quality of the one lane road leading inside it. It is administered by the Divisional Forest Officer, Shergaon Forest Division, Rupa (Millo Tasser, IFS). He is assisted by a Range Forest Office in Singchung and Beat Forest Offices in Ramalingam (close to Singchung) and Khellong. The absence of any settlement inside Eaglenest has minimized any problem of hunting.
The Critical Ecosystem Partnership Fund (CEPF), a consortium of major international and regional organizations, has identified the Eastern Himalayan region around Arunachal Pradesh (Nepal, Bhutan and all of Northeast India) as a critical global biodiversity rich area deserving of conservation focus. They identified the North Bank Landscape (i.e., north bank of Brahmaputra, extending up the Eaglenest slopes) and the Tawang region as worthy of particular focus.Critical Ecosystem Partnership Fund, Project database Eastern Himalayas Region Strategic Directions

BirdLife International has designated Eaglenest and Sessa sanctuaries as an Important Bird Area (IBA IN344), with Blyth's tragopan identified as a vulnerable species of the area.BirdLife International (2006) BirdLife IBA Factsheet, retrieved 10/1/2007 IN344 Eaglenest and Sessa Sanctuaries
This area is extremely important for the continued well-being of the Asian elephant. Elephants regularly move up from the Assam plains to the Eaglenest ridge at 3250 m in summer, perhaps the highest altitude that elephants reach in India. Extensive clearing of forests through illegal encroachments in Assam adjacent to Eaglenest has exacerbated elephant-human conflict in the plains; it has also meant that elephants now have to stay longer in the Eaglenest area and may lead to depletion of their food resource by exceeding the rate of regeneration.
