About These Birds
Tan-breasted Partridge
A medium-sized partridge (~335 g) of family Phasianidae, with plain tan-brown breast and muted brown upperparts. Endemic to the Natuna Islands of Indonesia. Inhabits tropical forest. Forages on the forest floor for seeds and invertebrates. Least Concern; while restricted to small islands, remains stable; its insular endemism makes it vulnerable to future habitat clearance or introduced predators.
Ahanta Spurfowl
A medium Phasianidae spurfowl (~548 g) of lowland and secondary forest edges in West Africa from Ivory Coast to Nigeria. Dark brown streaked white; red orbital skin. Forages on the ground in pairs or small groups for seeds, berries, and invertebrates. Tolerates forest fragments; Least Concern.
