The scarlet-collared flowerpecker (Dicaeum retrocinctum) is a species of bird in the family Dicaeidae, about 10cm long and is endemic to the Philippines where it found only in the tropical moist lowland forests in Mindoro, usually occurring below 1000m in the canopy and edge of the forest and in open country with scattered trees.

EBird describes the bird as "A small bird of lowland and foothill forest and more open wooded areas on Mindoro, slightly glossy black with a white belly and sides of the chest and with red patches on the throat, upper back, and in a stripe from the center of the chest down the belly.

[2] It is closely related to the red-keeled flowerpecker (Dicaeum australe) but has a longer, more slender curved beak.

Forest loss is a threat especially in its lower altitude limits which are more prone to legal and illegal logging, mining and conversion into farmland.
