Birding Areas

Bhalupong-Tenga Road  :  Passes along the eastern borders of the Eaglenest and Sessa sanctuaries and provides an excellent birding transect from 300-1600m altitude, that is, apart from the traffic. The corresponding areas inside Eaglenest are, naturally, better but this is an option for birders who dont have the time for Eaglenest.

Northern slope
Tenga  :  1200m.  Farmland and habitation.
Ramalingam  :   1780m.  Subtropical farmland, scrub and degraded forest.
Lama Camp  :   2350m.  Temperate broad-leaved primary and degraded forest.

Ridge   :   Temperate bamboo, conifer and broad-leaved forest and scrub.
Eaglenest Pass  :  2800m;   Bra-Top  :  3200m;   Piri-La  :  3000m?  
Bra-Top and Piri-La are the only 2 locations on this list not accessible by a vehicle and can be accessed by steep trails from Chakoo and Lama Camp. There has been much confusion involving these 2 names and Piri-La has been used to refer to both (even in Athreya & Kartikeyan 1995, and Choudhary 2003). The trail from Chakoo is signposted "Piri-La Trail". It climbs up to the ridge at 3100m and then bifurcates, the right branch climbing up immediately to Bra-Top and the left one following the ridge to Piri-La some distance away. Survey of India topo sheets show both these places. The Chakoo - Bra-top trail is tough but it passes through excellent birch, fir, rhododendron and bamboo and I've seen on that trail temminck's tragopan, fulvous-fronted parrotbills, black bear and even a red panda!

Southern Slope
Sunderview  :   2465m.  Temperate broad-leaved forest and roadside scrub.
Chakoo  :  2405m.  Temperate broad-leaved forest, meadows in ancient clear-felled patches.
Bompu  :   1940m.  Subtropical broad-leaved forest and bamboo, large patch of open scrub
Sessni  :  1250m.  broad-leaved forest. Old jhoom patches with secondary scrub.
Khellong  :  750m.  tropical forest, grazing meadows and degraded scrub.
Kamengbari - Doimara  :  100-350m.  Tropical forest, grazing meadows, shingle banks and cultivation.

The sanctuary extends from Eaglenest Pass to a little above Khellong along the road. The entire stretch from Lama Camp on the northern slope, up across Eaglenest Pass and down the southern slope to Khellong is prime birding area. Doimara and Kamengbari are also good but the corresponding areas in Pakke tiger reserve are better. A broad jeep track runs from Tenga to Kamengbari through Eaglenest Pass which makes for very comfortable roadside birding. It is this combination of roadside scrub adjacent to primary forest  just 20-30m away, apart from 3200m of altitudinal range, which makes Eaglenest a prime birding site. The large altitudinal range and the extraordinary bird assemblage requires a minimum of  6-10 days with a jeep and 10-14 days on foot to do justice to it.

See   town grade  and   accommodation  descriptions

Camp style accommodation, whether in tents or in empty sheds, is the only option between Lama Camp and Doimara. Tented camps in the lower reaches, at Khellong and Sessni, are not recommended because of elephant activity;  Doimara is safe because of the electric fence around the village. Perimeter trenches have been recommended to facilitate year-round camping in all areas. Elephants move up above Sessni only during summer (May - October) and so are not an issue for winter visitors.

Entry Permits

Arunachal entry permits are required for both Indians and foreigners and are checked on entry into Arunachal at Bhalukpong. The Circle Officers at Tenga/Singchung/Bhalukpong/Bomdila can issue fresh permits to extend the stay (for Indians only).
Forest entry permits are issued by the Divisional Forest Officer,  Pakke Tiger Reserve, Seijusa. E. Kameng district, Arunachal Pradesh. Phone +91-3778-222229 (off), 222230 (res), who also has additional charge of Eaglenest Wildlife sanctuary. The nearest Forest Dept presence is the Range Forest Office at Singchung.
The Bugun tribe of Tenga which lost its ancient rights over Eaglenest (along with the Sherdukpen tribe of Rupa) now charges an entry fee of Rs. 500 per day for foreigner and Rs. 100 for Indian visitors, which goes into the Bugun Welfare Society (and not Govt coffers). It has been proposed to reduce this to Rs. 250 and Rs. 50 respectively and charge Rs. 1000 per day for each 4-wheel vehicle (for both Indians and foreigners), to encourage trekking visitors and make vehicles pay for the damage they do to the fragile mountain road. The money collected will be used to provide local employment for patrolling the area and maintaining the road for visitors.


Walking is permitted inside the park.

To/From Tenga : Tenga is on the Tezpur-Bomdila-Tawang highway and connected by buses from Itanagar, Tezpur and Guwahati (Rs. 250 from Guwahati) and by shared jeeps from Tezpur (early morning and noon - Rs. 160 per seat). Full jeeps may also be hired from Tezpur, Balipara or Bhalukpong (Rs. 1200-1600) which will also facilitate birding the excellent Bhalukpong-Tenga stretch. The 135 km long drive, mostly in the hills, takes 3-5 hour.

Tenga to Eaglenest : The options are
1. Trek all the way with porters/camp staff
2. vehicle drop-off at Eaglenest Pass or beyond and a trek downhill with porters/camp staff. Drop-off vehicles can be rented in Tenga for Rs. 1000-1500
3. vehicle hired for the entire visit. Vehicles are available at Tenga and Bomdila for Rs. 1000-2000 per day plus fuel.

Inside Eaglenest  :  Access on foot through the broad jeep track is possible all through the year. Mountain bikes and motor-cycles (none available on hire locally) may also be used all through the year. Jeep access is usually limited to between November and April (May). The main rainy season is from May to October but heavy rains are a permanent threat and could cause a temporary road block (for jeeps) during any month. Snow on the ground is a possibility above 2000m for a few weeks from mid-January to early March.

Exit from Eaglenest : One can
1. Trek back over the Eaglenest Pass to Tenga
2. trek downhill and catch the daily bus from Doimara (6 days a week, with occasional no-shows)
3. arrange for a jeep pick-up inside Eaglenest and exit via Doimara or Tenga

Visiting these places by public transport will require a travel overhead of 3-4 days ex-Guwahati and one should keep a buffer for bus truancy. With a private vehicle the travel component will be 1-2 days. Logistical organisation will require a day at Tenga (alternatively, have Mr. Glow to do the organisation beforehand)See also  transport in W. Arunachal


All arrangements in Tenga - porters, camp staff, provisions, vehicle booking, local entry and accommodation permits etc - are best done through Mr. Indi Glow who lives in  Tenga, is aware of the needs of tourists (especially birders) and has been intimately associated with the Eaglenest Biodiversity Project. In association with the EBP he is involved in the process of identifying and training a reliable team of camp staff who understand that for birders "breakfast at 5.30 AM" means breakfast at 5.30 AM and that many visitors do not consider chilly a vegetable!
