East Kalimantan is the second largest Indonesian province, located on the Kalimantan region on the east of Borneo island. The resource-rich province has two major cities, Samarinda (the capital and a center for timber product) and Balikpapan (a petroleum center with oil refinery). Ever since Indonesia opened its mineral and natural resources for foreign investment in 1970s, East Kalimantan province has experienced major boost of timber, petroleum and other exotic forest products. The state-owned petroleum company Pertamina has been operating in the area since it took control oil refinery from the Royal Dutch Shell company in 1965.

The main problem in this province is the illegal logging which destroyed almost all the rainforest. Less than half the original rainforest still remains, in places such as the Kayan Mentarang National Park in the northern part of the province.

Birding in Kalimantan – Burung-Nusantara / Birds-Indonesia


Information about birding sites in Kalimantan, including key species, maps, access, local guides and resources. Kalimantan is massive, making up by far the biggest proportion of the island of Borneo. It is rarely visited by birders, however, many of whom prefer the easier birding of Sabah and Sarawak. For those interested to give Kalimantan a go you’ll certainly avoid the crowds, and several of the Bornean endemic species are much easier to be found here. Browse sites from the map or the table. Each site page will show links to birding trip reports, guides and other content that is relevant. Help us keep this information up to date by posting your experiences back here as comments…
