Bambusammer Emberiza variabilis

Small songbird of shady undergrowth, especially dwarf bamboo thickets, found in mid-elevation coniferous or deciduous forests during summer and in shady woodlands and parks during winter. Male uniquely slate-gray; both sexes have warm, rufous-brown rump and tail. Female intricately streaked, rather similar to Black-faced Bunting, but the latter lacks any rufous on tail, and face is not as cleanly striped. Call thinner and sharper than Black-faced Bunting.
