Yellow-billed Spoonbill
Platalea flavipes
Large dull-white bird with a long, spoon-shaped bill. Plumage often appears dirty. Diagnostic yellow facial skin, legs, and bill. Feeds singly or in small flocks. Submerges bill and makes a sweeping motion to capture prey. Found in a wide variety of freshwater habitats; rarely in marine environments.
识别特征
Measuring around 90 cm (35.5 in), the yellow-billed spoonbill has all white plumage. The long spoon-shaped bill, bare-skinned face, legs and feet are all yellow, while the iris is pale yellow. The sexes are similar in plumage and coloration. In the breeding season, the face is lined with black, long hackles develop on the chest, and the wings have black tips. The bill of the yellow-billed spoonbill is narrower and works more like a forceps than the larger-ended and more spoon-like bill of the royal spoonbill, which acts like a pair of tongs. Like all members of the ibis and spoonbill family, it always flies with its head extended.
分类信息
The renowned ornithologist John Gould first described the yellow-billed spoonbill, naming it Platalea flavipes although noting its distinctness from other members of the genus. Bonaparte erected the genus Platibis in 1856, and Gould followed this classification in his later work. He noted the species appeared in great numbers across New South Wales in 1839, particularly in the north between the Hunter and lower Namoi Rivers. The year had been wet, in contrast to droughts in previous years.<p>A 2010 study of mitochondrial DNA of the spoonbills by Chesser and colleagues found that the yellow-billed and roseate spoonbills were each other's closest relative, and the two were descended from an early offshoot from the ancestors of the other four spoonbill species. They felt the genetic evidence meant it was equally valid to consider all six to be classified within the genus Platalea or alternatively the two placed in the monotypic genera Platibis and Ajaia respectively. However, as the six species were so similar morphologically, keeping them within the one genus made more sense.

分布与栖息地
The yellow-billed spoonbill is found across eastern, northern and southwestern Australia, particularly around water, and has been recorded as a vagrant to New Zealand, Lord Howe Island and Norfolk Island. It is not found in Tasmania. It nests in trees, marshes or reed-beds, and often roosts in trees. It occurs in shallows of wetlands, and occasionally on dry pasture.

Tropical Boubou
Laniarius major
Robust black-and-white bushshrike. There is a pale cinnamon wash on the belly and a white stripe across the top of the wing. Found in dense microhabitats within forest, woodland, thickets, and gardens. Not particularly shy, but spends most of its time in dense cover, usually in pairs. Highly vocal bird with a variety of calls. The song is a synchronized duet of hollow hoots from the male and ratcheting calls from the female. Has a very similar color pattern to other boubous, but its underparts are paler than those of Southern Boubou and darker than those of Swamp Boubou. Has a white stripe on the wing, unlike Zanzibar Boubou.
Coastal Miner
Geositta peruviana
A pale terrestrial bird found only in coastal deserts of Peru. It is pale brownish-gray and lacks strong field marks. Very similar to Grayish Miner; Coastal Miner has a wing stripe, though this is only evident in flight. The two species mostly separate out by range, with Coastal Miner favoring the flat coastal plain and Grayish Miner preferring rocky slopes of hills and mountains. Coastal Miner is also similar to Short-tailed Field Tyrant, but lacks distinct wingbars and rump patch, and has a longer tail. Solitary, usually seen running through barren, sandy areas. Occasionally flies up to perch on a rock or bush, and also performs flight displays.
Hawfinch
Coccothraustes coccothraustes
Unique, chunky finch. Note the massive bill (steely gray in summer, pinkish in winter) and blue-gray hindneck, like a shawl on an orangey head. Broad white tail tip and white wing band show mainly in flight. Despite distinctive appearance, shy and easily overlooked. Favors mixed and deciduous mature woodland, especially with beech, oak, and hornbeam, where tends to feed and perch quietly, high in the canopy. Also feeds on the ground in autumn and winter, sometimes forming single-species flocks. Gives high-pitched “tsik!” and lower ticking calls.
