セアカハナドリ Dicaeum cruentatum

One of many flowerpeckers in which the male is brightly-colored and the female is predominantly brown. Adult male is black and white from below, but above it is bright red from the crown down to the rump. The female, while largely dull, can be distinguished from other flowerpeckers by her bright red rump that is often visible when hovering and foraging. Juvenile lacks the red rump, but has a white throat and is a much darker brown above than the similar Plain Flowerpecker. A lowland species, often found in gardens with flowering and fruiting plants, particularly mistletoe. Often detected through its metallic ticking calls.
