White-browed Piculet
Sasia ochracea
Minute woodpecker of lowland and foothill forests, where it forages in areas with dense low vegetation at the lower and middle levels. Predominantly rusty orange, with an olive-green crown and wings and a small but bright white eyebrow; the very similar Rufous Piculet lacks a pale brow. Male White-broweds have a bright yellow patch on the forehead which females lack. Often solitary, but can be found in small flocks and mixed-species foraging groups. Gives an explosive, squeaky, often descending chatter and sharp “chip” notes.
识别特征
This small piculet has olive-green upper parts tinged with chestnut and grows to a length of up to 10 cm (4 in). The under parts are cinnamon or rufous, sometimes yellowish on the flanks. The stubby tail is blackish. The crown is green, and there is a white streak above and immediately behind the eye, the latter being surrounded by a ring of bare pinkish or reddish skin. Males have a small golden-yellow patch on the forehead which females lack. Juveniles are duller in colour than adults, greener above and greyer beneath. The beak is grey, the iris is red and the legs are yellow or orange, the feet having just three toes, (four being the norm in the woodpecker family). In southern Myanmar and southeastern Thailand, where their ranges overlap, the white-browed piculet can be confused with the very similar rufous piculet (Sasia abnormis), but differs in the white streak above the eye and the darker beak.

行为
It forages in the understory layer not far above the ground, pecking and probing with its sharp beak. Its diet consists of small insects, bark beetles, ants, termites, spiders and other small invertebrates. It often forages in pairs or may join small flocks of mixed species, sometimes descending to the ground, where it may hop for short distances.<p>This bird uses pieces of bamboo to make its nest. It picks up bits of broken bamboo with its feet, and uses its beak to pull away partially broken fragments. Breeding takes place between March and July.

Northern Crombec
Sylvietta brachyura
A small and virtually tailless warbler with a gray-brown back and rufous underparts. There is some geographical variation; the throat can be dull rufous, dull white, or bright white. Always shows a gray-brown eye-line. Found in a wide variety of savanna and woodland habitats. Similar to Red-faced Crombec, but has a strong eye-line, and in the area of overlap, usually shows a bright white throat. The song is a quick, jumbled whistled phrase that varies somewhat across the range. The call is a rapid wooden trill.
Biak Flycatcher
Myiagra atra
A fairly small bird of wooded areas on the Bay Islands. Low crest is flattened at the front and rounded at the back. Male is glossy black with a purplish-blue iridescence. Female is medium gray above, pale gray below with brownish flight feathers and a darker mask, contrasting with the pale throat. Male similar to male Shining Flycatcher, but Biak is found in forest rather than waterside thickets and is smaller and less glossy. Often found in pairs and female has gray rather than rufous upperparts. Voice, a simple up-and-down whistled song and raspy call.
Hawaiian Crow
Corvus hawaiiensis
This large, black, and extraordinarily loud bird vanished from Hawaiian forests in 2002. Fortunately it survived in aviaries, and captive bred birds began to be released back into the wild in 2016 in remote parts of the Big Island; early signs are promising with several pairs attempting to nest. Known to Native Hawaiians as ʻAlalā, it is the only crow or crow-like bird currently found on the archipelago. It is much bigger than the crows found on the US mainland, and is closer in size to a raven. Gives a variety of loud caws, croaks, and squeals.
