The scarlet-collared flowerpecker (Dicaeum retrocinctum) is a member of the family Dicaeidae, about 10 cm long and is endemic to the Philippines. It is found only in Mindoro, usually occurring below 1000m in the canopy and edge of the forest and in open country with scattered trees. The call is a series of notes similar to striking two stones together plus a high-pitched `zeet zeet zeet`. It is closely related to the red-keeled flowerpecker (Dicaeum australe) but has alonger, more slender curved beak. The upperparts are black with a slate blue gloss and scarlet collar across the upper back. The throat and upper breast are black with a small red patch on the throat; the belly is white with a scarleet ventral stripe bordered with black.It is threatened by habitat loss.
