Little green-pigeon Treron olax

This aptly-named forest species is the smallest of the green-pigeons. Males are highly distinctive, with a blue-gray head and neck, orange chest, pinkish-maroon back, and green belly. Females are duller, but their combination of size, gray crown, and contrasting yellow-green chest serves to tell them apart from other green-pigeons. Pairs often forage and perch together, often on exposed bare branches. Like other pigeons, frequently gathers at fruiting trees. Song is a series of strangely buzzy rising whistles.
