Banded Bay Cuckoo
Cacomantis sonneratii
Slender brown cuckoo with extensive fine barring and pale face and underparts. Found in lowland and foothill forests, where, like many cuckoos, it can often be inconspicuous in dense foliage. Listen for its two distinct songs, a high rising “smoke-yer-pep-per!” and a series of rising whistles.
识别特征
The adults are bright rufous or bay on the head and back and are broadly barred with dark brown. The bill is long and slightly curved. A whitish supercilium is distinctive above a dark eye-line. The wing is darker and tail is graduated with a dark brown centre. The tail has a subterminal black band and white tips to the feathers. The sexes are alike. The iris is yellow and the bill is black while the base of the lower mandible is greenish grey. The tarsi are grey. The juvenile is similar but has a pale lower mandible and white fringes to the feathers of the upper body.<p>The overall length is about 22 cm making it about the same size as the syntopic Cacomantis merulinus and Cacomantis variolosus. The hepatic forms of those can be similar but supercilium, long beak and barred tail distinguish this species.
分类信息

The species epithet is after the French naturalist and explorer Pierre Sonnerat.<p>Four subspecies are generally recognized:<p>Some sources also recognize malayanus (Chasen & Kloss, 1931) from Peninsular Malaysia and schlegeli (Junge, 1948) from Sumatra, Borneo and Palawan (SW Philippines).

Tabora Cisticola
Cisticola angusticauda
Medium-sized, long-tailed, plain cisticola. Note the rufous cap and the white tip to the tail. The tail is slightly shorter in non-breeding plumage. Found locally in a variety of savanna habitats, including both acacia savanna and broadleaf woodland. The song is a quick, high-pitched piping. As with other cisticolas, habitat and vocalizations are important to identification. Similar to Rock-loving Cisticola, but smaller, slimmer, and not associated with rocky habitat. Somewhat like Siffling Cisticola, but has a rufous cap.

Boat-billed Tody-Tyrant
Hemitriccus josephinae
Tiny, inconspicuous flycatcher with an oversized bill. Plumage generally olive above and yellow below, with faint breast mottling; most readily identified by its large, long bill with entirely pale mandible. A rare resident of tall rainforest, where it seems to prefer areas with many dense vine tangles. Usually encountered alone, sitting deep inside a vine tangle in the mid-story and making short sallies to foliage for insects. Almost always first detected by voice: a series of two or three short hollow notes, somewhat musical and descending in pitch. Unlikely to be confused if seen well, on account of its large bill. Voice is somewhat similar to that of Pelzeln’s Tody-Tyrant but is deeper and seldom exceeds three notes; the two species occupy entirely different habitats.

Buller's Shearwater
Ardenna bulleri
Striking large shearwater with distinctive dark "M" pattern on upperwings. Also note crisp dark cap and clean white underwings and belly. Looks silvery-gray above when fresh, but worn birds can be more brownish. Graceful flight style. Usually easily separated from other shearwaters by wing pattern. Breeds on islands off New Zealand; ranges across the Pacific during nonbreeding season; uncommon off the west coast of the U.S. in fall. Rarely seen from land, prefers to stay offshore. Found singly or in flocks with other shearwaters.
