Tawny-tufted Toucanet
Selenidera nattereri
Small toucan. Look for the blue patch on a reddish bill. Males have a black crown, throat, and breast; in females, the black is replaced by chestnut. Occurs in humid forest, including white sand forests. Call is a slow, deep series of “ggrawnk” to “ggrraaw” notes, easily overlooked.
识别特征
The tawny-tufted toucanet is 32 to 33 cm (13 to 13 in) long and weighs 148 to 165 g (5.2 to 5.8 oz). Males and females have the same bill pattern but the female's bill is shorter. The bill has a vertical red line at its base. Its culmen is green to lime green; the rest of the maxilla is red but for a blue patch near the base and pale "teeth" along the tomium. The mandible is mostly brownish red (sometimes greenish horn-colored) with a blue patch near the base, a green tip, and vertical white lines along the mid section. Both sexes have pale blue bare skin around the eye and a yellow to tawny tuft of feathers behind it. Males have a black head, nape, chin, throat, and belly. Their upperparts are green with a yellow band on the lower neck. Their tail is green with chestnut tips on the central three pairs of feathers. Their flanks are yellow to rusty and their undertail coverts are red. Females have a chestnut crown to the shoulders, a rusty chin and belly, greenish yellow flanks, and paler facial skin and tuft than males.

分布与栖息地
The tawny-tufted toucanet is patchily distributed from extreme eastern Colombia through southern Venezuela into northwestern Brazil north of the Solimões (upper Amazon) River as far east as the upper Rio Negro. Unconfirmed sight records in Guyana lead the South American Classification Committee of the American Ornithological Society to call it hypothetical in that country. It inhabits forests, usually those on sandy soil and near waterways.

Small, grayish-brown bird with a scaly white bib, a dark black facial mask, buffy belly, and a gray bill. Juveniles very plain brown, with faint outline of adult's mask.

Melanesian Kingfisher
Todiramphus tristrami
A Collared-type kingfisher found on a broad band of islands northeast of New Guinea, ranging from the Bismarck Archipelago east to Guadalcanal in the Solomons. Varies across range; note blue-green upperparts, pale collar, slender dark mask, and bicolored bill. Compare with Sacred Kingfisher; Melanesian averages darker and bluer above. Inhabits a range of island habitats, often in coastal regions but also well inland, especially in areas without other kingfishers. Listen for loud, harsh, far-carrying calls.
