Crimson-crowned Flowerpecker Dicaeum nehrkorni

A tiny, short-tailed songbird. Unmistakable male is dark with a red cap, breast spot, and rump. Underparts white, with a dark vertical line on the belly and white tufts on sides of breast. Female is gray, with red confined to rump; this color patterning is diagnostic. Juvenile resembles female, but lacks the red rump. Singles or pairs inhabit the upper reaches of hill and montane forest and forest edges. Restricted to Sulawesi. Gives thin, high-pitched “tzeet” and “kwit” call notes. Song starts with “tzeet-tzeet” phrases, then descends into a rapid warble.
