Golden-rumped Flowerpecker Dicaeum annae

A tiny, nondescript, short-tailed songbird with a stubby bill. Olive above and pale below, with gray-washed flanks and a white moustache in both sexes. Males show a yellow rump that is absent in females. Juveniles resemble females but are duller below, with a pale-based bill. Pairs and singles can be found high in trees in wooded areas, forest patches, and edges within the lowlands and mountains. Restricted to the Lesser Sundas. Pale moustache and all-dark undertail separate this species from Thick-billed Flowerpecker. Gives a very high-pitched descending series, “tzee-tzee-tzee-tzee-tzeer-tzeer…”, as well as a soft trilling sound.
