About These Birds
Chestnut-bellied Partridge
A medium-sized partridge (~270 g) of family Phasianidae, with a rich chestnut belly and boldly patterned head. Endemic to the montane forests of Java at 800–3,000 m elevation. Inhabits primary and secondary highland forest. Forages on the forest floor for seeds, berries, and invertebrates. Least Concern; well represented in Java's mountain national parks despite the island's high human population density.
African Blue Quail
A tiny Phasianidae quail (~42 g) of tall grasses and moist savanna across sub-Saharan Africa. Males have a slaty-blue face and rusty-buff flanks; one of Africa's smallest birds. Highly secretive; rarely flushed. Feeds on tiny grass seeds and invertebrates. Migratory or nomadic following rains. Least Concern.
