Sumatran Flowerpecker (Dicaeum beccarii)

Hitherto treated as conspecific with D. ignipectus and D. cambodianum (along with D. luzoniense), but differs from cambodianum in characters given under that species (see above). Differs from D. ignipectus in its lack of red breast in male (3); blackish-grey vs blackish lower head sides and ventral streak in male (1); greenish vs whitish-buff central underparts in female (3); evidently different song (but only one recording; ns)#R. Proposed race vanheysti (from Berastagi, in N Sumatra) is a synonym. Monotypic.
