Gunung Ambang Nature Reserve

Gunung Ambang Nature Reserve is a preserved area in the north of the island of Sulawesi in Indonesia.

There are a number of marshes and small lakes and, particularly near the edge of the park, trees have been felled and there are clearings and the growth of secondary forest.

The purple-bearded bee-eater is an elusive denizen of woodland verges and open areas and the olive-flanked whistler is a rare upland species.

In the upland areas of the nature reserve are pigeons, lorikeets, parrots, including the golden-mantled racket-tail, and hornbills, although these large-billed birds are uncommon.

The Celebes crested macaque is found in the reserve and the spectral tarsier is also present but both of these are very wary of humans.
