scarlet-headed flowerpecker Dicaeum trochileum

Male’s bright red head, breast, and back makes him unmistakable. Female is brownish above and pale below, with a red rump; can be similar to female Scarlet-backed Flowerpecker, but note Scarlet-headed’s grayer tones overall, especially on the flanks (female Scarlet-backed has pale buff or faded yellowish flanks). A common sight in lowland and lower foothills, where it inhabits gardens, cultivated areas, forest edge, and open or degraded forests. Song is a quiet series of very high tinkling notes; most common call is a short buzzy “bzzt”.
