Metallic Starling has finer bill, tapered tail. Inhabits great variety of habitats, where it chases insects mercilessly. Perches prominently, delivering harsh, squawking calls, often mimicking other species such as butcherbirds and kingfishers.
识别特征
Its basically black plumage is iridescent with blue and purple highlights. Its eyes are crimson.The most remarkable characteristic of its appearance is its tail, which is described by Morcombe as "long, outcurved and forked" and on first examination looks like its feathers are crossed over – like crossing your fingers. Young drongos lack the highlights and spots and their eyes are dark brown.

行为
The spangled drongo displays uninhibited and sometimes comical behaviour as it swoops and perches in search of insects, small birds, and occasionally, small skinks. When it seasonally visits urban areas, it is easily tamed by throwing small pieces of raw meat into the air, when it will accurately swoop and catch them midair.<p>Whilst this bird is often silent, it sometimes makes astonishingly loud, complex, and entertaining calls that may sound like a "sneeze". The spangled drongo is an amazing mimic, taking most of its vocabulary from the sounds heard in the vicinity and weaving them into a song.<p>The spangled drongo is the only drongo to be found in Australia. These birds are altitudinal and latitudinal migrants, and in the high-altitude areas around Brisbane in Queensland, they arrive in late spring and leave with their new crop of juveniles in midsummer. Nests are cup-shaped in open spaces, where predators have difficulty accessing them without being seen, 75% up the canopy. Each year, they produce three to five young.

Brown Babbler
Turdoides plebejus
A dull brownish babbler with brightly colored eyes. Found in moist woodland, dense savanna, scrub, gallery forest, forest edge, cultivated areas, and gardens, almost always in groups that forage actively on the ground. Similar in shape, size, and overall brown coloration to Arrow-marked Babbler, but there is only minor overlap in range, and Brown Babbler can be separated by the paler face and throat and the less pointed white markings on the underparts. Calls include a raspy babbling and a dry clucking, both usually by a whole group in chorus.
Black Guillemot
Cepphus grylle
Small seabird of coastal areas of the North Atlantic and Alaska. Breeding plumage is entirely black with bold white patch on wings and bright red legs. Changes dramatically in winter to whitish overall with some dusky markings on body and black wingtips. Often found in shallower coastal waters including from shore. Dives to hunt for fish and invertebrates. Nests in crevice or burrow in a cliff or around large rocks.
Pere David's Laughingthrush
Pterorhinus davidi
A plain clay-brown laughingthrush with a long, curved yellow bill. Largely without distinguishing plumage features, but note weak white brow, blue-gray tinge to the wings, and small black patches on the “elbow” and face. The only laughingthrush in much of its range. Forages in hilly and montane regions, where it often moves about noisily in medium-sized flocks in scrubby, brushy habitat, often near waterways. Long rambling song melodious and thrush-like; calls include fluid whistles, nasal chattering, and quiet peeping.
