Yellow-billed Tern
Sternula superciliaris
Small tern with a robust yellow bill. In the breeding plumage has an extensive black crown and small white forehead patch. In the nonbreeding season, the crown is white with a dark mask. Distinguished from Least Tern by the lack of a black tip to the bill and more extensive dark in the wings. Found along large rivers and lakes and seasonally on the coast.
Identification
It measures approximately 23-25 centimeters in body length and weighs 40-57 grams. It has a yellow beak and feet, silvery grey wings and white underbody and forehead. Its crown, nape, and eyeline are black. Juveniles are brown and white without the black cap.

Sunset Lorikeet
Trichoglossus forsteni
A fairly large long-tailed parrot with unmistakable striking coloration. Green with a dark purple head, a red bill, a lime-green collar, and a broad red chest patch above deep purple underparts. Juveniles duller, with a brownish bill. Found in noisy groups, mainly in the lowlands but also up into the mountains, where it occupies the edges of forests and wooded areas. Restricted to Lombok and Bali, where it is the only lorikeet. Gives shrill screeches: “EEEEK!”

Buckley's Forest-Falcon
Micrastur buckleyi
Elusive falcon of lowland and foothill rainforest east of the Andes. Note black upperparts, white underparts, white hindcollar, and dull yellow face. Female may show white spots on wings. Immature is barred underneath with brownish nape. Adult is very similar to pale morph Collared Forest-Falcon but slightly smaller; ID is best confirmed by voice. Typical song of Buckley’s is “kawah, koh”, sometimes followed by a lower “koh” note. Usually stays inside forest and is infrequently seen.

Black-tailed Whistler
Pachycephala melanura
Chunky, rounded songbird with heavy thick bill. Found across a wide range of habitats across its range: largely mangroves in Australia, but also inhabits freshwater swamps in New Guinea and forests and forest edge on smaller islands. Male has an olive-yellow back, black head, white chin, bright yellow underparts, and thick yellow hindcollar. Female plain gray above, paler gray below, with yellow undertail and in some subspecies a yellow belly. Overlaps very marginally with the very similar Golden Whistler in eastern Queensland, but note mangrove habitat as well as slightly longer bill and darker uppertail; also note significant yellow on underparts in female and different song. Vocalizations include variations on whistled songs, sometimes with a whip-like ending.
