We present the results of bird surveys conducted in 2000 and 2006 at 13 sites in the interior lowlands and foothills (<400 m asl) of Central and East Kalimantan, Indonesia. The study area spans c.170 km east–west between the middle and upper reaches of the Barito and Mahakam Rivers, and more than 100 km north–south from the foothills of the Muller Range. Habitats surveyed include mixed dipterocarp forest, heath forest (kerangas), riparian forest and converted lands on a variety of substrates. A total of 226 species was recorded, including five Vulnerable species (Crestless Fireback Lophura erythrophthalma, Large Green Pigeon Treron capellei, Lesser Adjutant Leptoptilos javanicus, Hook-billed Bulbul Setornis criniger and Bornean Wren Babbler Ptilocichla leucogrammica) and 59 Near Threatened species. Habitat, land use and soil quality varied widely across the study area. The north-west section of the study area boasts large tracts of intact, continuous-canopy dipterocarpand heath forest and is likely to support viable populations of a variety of rare and threatened species. The influence of logging disturbanceis briefly discussed, and the bird communities of dipterocarp and heath forests are broadly compared.
