Amazon Kingfisher
Chloroceryle amazona
Medium-sized kingfisher of tropical lowlands. Found singly or in pairs, along rivers and at the edges of ponds and lakes, often perched on wires or bare snags. Mainly flies low over the water. Size similar to Belted Kingfisher, but black bill much more massive and crest more tufted. Also differs from Belted in its dark oily-green head and upperparts. Green Kingfisher is much smaller with bold white spots and bars on the wings.
识别特征
The Amazon kingfisher is about 30 cm (12 in) long. Males weigh 98 to 121 g (3.5 to 4.3 oz) and females 125 to 140 g (4.4 to 4.9 oz). It has the typical kingfisher shape, with a shaggy crest and long heavy bill. The bill is black with some pale yellow at the base of the mandible and its legs and feet are dark gray. Adult males have dark bronzy green upperparts divided by a white collar. They have a white chin and throat, a rich rufous breast with dark green sides, and a white belly with dark green streaks on the side. Adult females lack the rufous breast but the green of the sides extends across the breast almost to its middle. Juvenile males have a buffy rufous breast and both sexes have buff spots on the upperwing coverts and a large yellow patch on their bill.
分类信息
The first formal description of the Amazon kingfisher was by the English ornithologist John Latham in 1790 under the binomial name Alcedo amazona. The current genus Chloroceryle was erected by Johann Jakob Kaup in 1848. The species is monotypic.

分布与栖息地
The Amazon kingfisher is found from the Mexican states of Sinaloa and Tamaulipas south through Central America into Colombia and Venezuela and separately east of the Andes in every South American country except Chile, reaching as far south as central Argentina. It has been recorded as a vagrant to Aruba, Trinidad, and Texas. It inhabits large rivers, both slow- and fast-flowing, and the wooded shores of lakes and freshwater lagoons. It also occasionally occurs in brackish lagoons, mangroves, and tidal estuaries. It favors open landscapes rather than dense forest. In elevation it is mostly found below 1,200 m (3,900 ft) but occurs as high as 2,500 m (8,200 ft) in Venezuela.

Blue-masked Leafbird
Chloropsis venusta
The smallest and most unique-looking of the leafbirds. Stout-bodied, with a relatively long, faintly curved bill. Both sexes have a blue face and yellowish-green belly; males also have an orangish chest and purplish throat. Endemic to Sumatran foothill forests, where it is typically encountered in pairs up in the canopy. Songs include a high-pitched jumble of notes and a repetitive squeaky “tsi’wee, tsi’wee”; calls include a dry “chit” and a sputtering rattle.
Angola Swallow
Hirundo angolensis
A small swallow with blue upperparts, chestnut forecrown, and throat with a narrow incomplete dark breast band and gray underparts. Singles, pairs and groups are residents and intra-African migrants to open grassland, cultivation, and wetland fringes. Barn Swallow is similar to Angola but is larger with much longer outer tail feathers, broader complete breast band and white underparts; Ethiopian Swallow has buff (not chestnut) throat and white (not gray) underparts. Vocalizations include typically swallow-like weak twitters.
Lesser Melampitta
Melampitta lugubris
A shy, medium-sized ground bird of montane forest. Velvety black plumage with long legs, a fairly short tail and a bulbous head. Eye color is red in male and brown in female. Hops around looking for food. Somewhat similar to Blue-gray and Smoky Robins, but Lesser Melampitta is larger and black rather than gray. More often heard than seen. Call, a rather unbirdlike “klik!” or “puk-klik!”.
