Orange-bellied Flowerpecker vs Plain Flowerpecker

Orange-bellied Flowerpecker

Dicaeum trigonostigma

Tiny7 gForest

Male is distinctive, and shows slaty-blue upperparts (crown/nape/wings/tail) except for a large triangular orange patch on the mantle. It has a fairly thin and short bill that is slightly curved downwards at the tip. Upper-breast and throat are a lighter greyish blue; from the lower breast to the vent is a gradient from fiery orange (on the lower breast) to yellow (on the vent). Female is much duller, and is mostly drab olive brown overall, except for its pale orange rump and yellow belly.

Plain Flowerpecker

Dicaeum minullum

Tiny6 gForest

These birds are tiny (9 cm long) and there is no marked difference between the males and females. The subspecies found in northeastern India, extending into Myanmar, Laos and southern China is called olivaceum by earlier authors but is treated by Pamela C. Rasmussen as a separate species Dicaeum minullum (which includes the population minullum from Hainan Island and is now termed as the plain flowerpecker in the more restricted sense).
