Sumatran Leafbird

Small bright green lorikeet with bright yellow cheeks. Also note olive-yellow crown, yellow-edged “scaling” on the belly, and bright red bill. Well-patterned underparts, bill color, and more pointed tail distinguish this species from racquet-tails, the only other similarly-sized green parrots on Sulawesi; much larger and longer-tailed than hanging-parrots. Flocks in wooded and open areas, gathering at fruiting and flowering trees. Primarily in middle elevations; less common in lowlands. Gives high-pitched shrieking calls. Formerly lumped in with Sula Lorikeet under the name “Yellow-and-green Lorikeet.”

Small brown bird with a flashy white patch on the back of an erect crest. Inhabits broadleaved forests and adjacent second growth, parks, and gardens in hilly and montane regions. Often travels in flocks, sometimes associating with other species. Usually forages at middle levels in the forest. Gives dry trills and buzzy whistles.

A small swift with short square tail (rounded when spread), a relatively large head, black upperparts, and a white rump patch. It has a distinctive wing shape with a hooked outer wing and a bulging mid-wing that is pinched at the base. Underparts grade from a brown-gray throat to a pure white belly without any sharp demarcation. Spines on the tail are minute and hard to discern in the field. Flight action, with rapid wingbeats and short glides, is different from that of Little Swift. Mostly seen in flocks, sticking to woodlands and hills, though it descends to the adjoining plains just after showers.
