Moustached Hawk-Cuckoo

Hierococcyx vagans

Large hawk-like cuckoo, dark gray-brown above with streaked underparts and long tail with broad dark bands. Distinctly falcon-like facial pattern distinguishes this species from other hawk-cuckoos. Can be difficult to see, concealed in dense vegetation of lowland and foothill forests and their edges. Vocalizations include a bright two-note “wheup wheup!” and an ascending series of similar notes that abruptly stops after reaching a feverish pitch.

Identification

The moustached hawk-cuckoo is 25–30 cm (9.8–11.8 in) long, and it weighs about 58–63 g (2.0–2.2 oz). The crown and nape are grey. The ear coverts are white, and there is a blackish moustache. The back is brown, and the tail has brown bands and a buffy or white tip. The flight feathers have buffy bars. The underparts are creamy-white, with blackish streaks. The eye is dark brown or grey, with a yellow eye-ring around it. The beak is black, and the feet are orange-yellow. The juvenile bird's back and wings are blackish, and it has black streaks on its breast. The fledgling also has a moustache.

Behavior

This cuckoo eats insects and small fruits. It has been seen in mixed-species foraging flocks. It is usually found in thick canopy. Males sing at fixed locations in the canopy, its call being chu-chu or kang-koh repeated every two seconds. It also gives a whistling peu peu that becomes hi-hi and then stops. It has been observed parasitising Abbott's babbler and the rufous-winged philentoma. In mainland Southeast Asia, the breeding season is June to August.

Collared Kingfisher

Collared Kingfisher

Todiramphus chloris

A mid-sized kingfisher with a variable plumage pattern; nearly 50 subspecies described worldwide. All of them have a greenish-blue crown, a white spot above the lores, a black mask extending down as a narrow band across the hindneck, and a white collar. Upperparts are greenish-blue, rump brighter blue, with blue wings and tail and white underparts. Female and juvenile slightly duller. Subspecies mainly differ in plumage, with upperparts varying from blue to green to olive-toned, white loral spot sometimes extending as a supercilium, and underparts sometimes buffier. Gives various vocalizations, but most common call is a “kek-kek-kek-kek.” Frequents mangroves and tidal creeks, though sometimes inhabits other habitats, including coconut plantations in islands.

Marigold Lorikeet

Marigold Lorikeet

Trichoglossus capistratus

A handsome long-tailed green parrot with a purple head, a red bill, and a striking yellow chest and collar. In flight, note conspicuous yellow underwings. Juveniles have a brown bill and are duller in color. Pairs and small groups inhabit a variety of forest types in the lowlands of its limited range in the Lesser Sundas. Differs from Olive-headed Lorikeet in being a larger, lowland species with a dark purple-colored head. Regularly gives ear-splitting shrieks.

Dusky Flycatcher

Dusky Flycatcher

Empidonax oberholseri

Dull grayish flycatcher, very similar to other flycatchers, especially Hammond's and Gray. Generally grayish with green-tinged back and pale yellow wash on belly. Wingtips shorter than Hammond's Flycatcher and typically found in brushier, more open habitats such as forest edge, but not as open and sparse as Gray Flycatcher. Listen for classic “bean-dip” call as well as dry "whit" note, similar to Gray but noticeably different from Hammond's. Without an excellent view, silent birds often best left unidentified.
