Sahul sunbird Cinnyris frenatus

Tiny and active sunbird of forest edges, parks, and gardens; ranges from Sulawesi east to the northern Moluccas, New Guinea, and northeastern Australia. Both sexes have a plain olive back, a yellow belly, and white tail edges that are flared out in flight. The male flashes an iridescent blue throat while the female has a yellow throat and eyebrow. In parts of range, female Sahul may be confused with female Black Sunbird; note that species’ unmarked gray head and shorter, less curved bill. Gives a buzzy, twittering song, as well as a rising “dwee”, a familiar sound even in cities. Formerly grouped with other, closely related species under “Olive-backed Sunbird.”
