Large-billed Scrubwren
Sericornis magnirostra
Small brown bird with long pointed bill, long pinkish legs, and off-white eye ring. Inhabits rainforest and wet eucalypt woodlands, where it forages for insects mostly in lower and mid-canopy, often on tree trunks; unlikely to be seen on the ground.
识别特征
The large-billed scrubwren is 11.5 to 13 cm (4.5 to 5.1 in) in length and weighs 10 g (0.35 oz). It has a dark reddish-brown eye in a pale buff face, with a longish, black bill inclined slightly upwards. The upperparts are light grey-brown with an olive tint, the throat is a pale buffy-white, the belly greyish, and the rump and tail light rufous-brown.
分类信息
The large-billed scrubwren was described by ornithologist John Gould in 1838.<p>The generic name Sericornis derives from Ancient Greek serikos 'silk' and ornis 'bird'. The specific epithet derives from Latin magnus 'great' and rostrum 'bill'.<p>It was placed in the family Pardalotidae in the Sibley-Ahlquist taxonomy, but this has met with opposition and indeed is now known to be wrong. Instead, the large-billed scrubwren belongs to the independent family Acanthizidae.<p>There are three recognised subspecies: Sericornis magnirostra magnirostra, S. m. viridior, and S. m. howei.

分布与栖息地
The large-billed scrubwren is found from near Cooktown in northern Queensland to Kinglake and the Dandenong Ranges, near Melbourne, Victoria. The distribution of the 3 subspecies corresponds to 3 discontinuous areas within its overall range: the nominate subspecies Sericornis magnirostra magnirostra is found from the Clarke Range, inland of Mackay, Queensland to East Gippsland in Victoria; S. m. viridior is found in northeast Queensland from Mt Amos, south of Cooktown, to the Paluma Range National Park, near Townsville; and S. m. howei is found in West Gippsland and the Strzelecki Ranges of southern Victoria. Its preferred habitat is rainforest in the tropics and wet sclerophyll forest in temperate areas. It is sedentary and more common in the north of its range.

行为
The large-billed scrubwren breeds from July to January, mainly in November and December. It constructs a rough, domed nest of bark, grass and moss, lined with feathers and set in creepers, tree-ferns or palm-fronds. It often occupies the abandoned nest of other species, notably the yellow-throated scrubwren (Neosericornis citreogularis). A clutch of 3 or 4 eggs, measuring 19 mm × 15 mm (0.7 in × 0.6 in), is laid. The eggs are dull white to pale purplish-brown in appearance with fine spots at the large end. The incubation period is unknown and the nestling period is about 13 days. The nests are parasitised by the fan-tailed cuckoo (Cacomantis flabelliformis) and the chestnut-breasted cuckoo (C. castaneiventris).<p>The large-billed scrubwren forages in the low to middle levels of the forest, often in small flocks. It is insectivorous, gleaning various arthropods, including spiders, ants, wasps, beetles, and lepidopteran larvae, from the bark of tree-trunks and branches, and amongst debris suspended in vines and epiphytes.<p>The large-billed scrubwren is mostly silent, but occasionally makes a penetrating territorial call "s-cheer s-cheer", a sharp, loud "chwip-chwip" or a chattering "sip-sip" while feeding.
保护状况
The large-billed scrubwren has a wide distribution and a stable population, and is classified as of least concern on the IUCN Red List.

Long-tailed Fantail
Rhipidura opistherythra
A small brown songbird with a long tail, often held cocked or fanned. Upperparts largely rufous except for a grayer head with a pale brow. Shows a white throat and uniform buff underparts. Inhabits lowland forest and sometimes mangroves. Confined to the Tanimbar Islands. Told from Arafura Fantail by the lack of a white tip to the tail and the absence of a black breast patch. Gives a distinctive, repetitive, see-sawing two-note song phrase, “wee-oo-wee-oo-wee-oo,” rising on the first note, falling on the second. Also gives nasal jittering calls.
Tambourine Dove
Turtur tympanistria
Small dove with a dark brown back and pale face and underparts. In flight, the wings show rufous patches. Found in rainforest, gallery forest, thickets, moist woodland, and plantations. Shy understory species that is most often seen on the ground. Song is a long series of hollow “hoo” notes with a stuttering start and a long, even end. Separated from wood-doves by its darker back and paler face and underparts.
Meratus Blue Flycatcher
Cyornis kadayangensis
A recently described species from lower montane rainforest in SE Borneo. Orange chest and white belly. Male has deep blue upperparts and female gray-brown upperparts with pale eyering. Found singly or in pairs in shady undergrowth to mid-storey. Similar to Malaysian and Bornean Blue Flycatchers but usually found above the elevation of those species. Male Bornean is paler blue above and female lacks eye-ring. Malaysian lacks the extensive orange chest. Song, several descending notes followed by a single high-pitched note. Call, a single, hollow note or high-pitch double note.
