Ladder-tailed Nightjar
Hydropsalis climacocerca
Large nightjar of tropical lowlands, often found near waterways. Sandy brown with indistinct light markings and a fairly long tail; in flight, males show large white wedges on outer tail feathers. Roosts during the day in vegetation along the edges of oxbow lakes and rivers and forages around sandbars and river edges at night. Does not call often, but occasionally gives soft chirping calls in flight.

分布与栖息地
The ladder-tailed nightjar is found in all regions of the Amazon basin, and in the northeast the Guiana Shield and the Guianan countries; its range does not extend east of the Amazon River outlet, (the island: Ilha de Marajo). At this same outlet, in the region of the Xingu River confluence, the range extends southward and is in the lower two-thirds of the drainage of this north-flowing river.<p>In the west the species range is adjacent to the Andes foothills. In the north, the range extends into southeastern Venezuela, and only the upper third of the Caribbean north-flowing Orinoco River drainage, the area of the eastern Orinoco River Basin and uplands bordering western Guyana.<p>In the very headwaters of the southern Amazon Basin, the upstream half of the river drainages, both in the southeast and southwest, the range overlaps with its sister Hydropsalis species, the scissor-tailed nightjar, which ranges into southeast Brazil through the caatinga, cerrado, and pantanal south into Argentina. The two species cover all of South America east of the Andes cordillera from central Argentina to the Caribbean coast; the exception is a small region centered southeast of the Amazon basin in the vicinity of Maranhão, Brazil.

Tropical Kingbird
Tyrannus melancholicus
Large, ubiquitous yellow-bellied flycatcher found throughout most of Middle and South America, though tends to be uncommon at the far northern end of its range in the U.S. A classic “telephone wire” bird along roadsides and in towns. Prefers open areas with some trees and water. Most abundant in lowlands and foothills, but ventures up to over 3,000m in some parts of range. Listen for sharp, high-pitched twitters. Nearly identical to Couch’s Kingbird, which overlaps from Texas to Belize; best separated by voice. Larger and longer-billed than Western and Cassin’s Kingbird; also note paler brownish tail. Also very similar to White-throated (longer, forked tail) and Snowy-throated (dark mask) Kingbirds in some parts of South America.
White-browed Scrubwren
Sericornis frontalis
Small scrubwren with white eyebrow and pale iris. Has a dark face with a clear white eyebrow and chin stripe. Primarily olive-brown with a black-and-white shoulder patch and paler front. Chin is white with varying levels of black streaking depending on the location. This species is widespread across eastern coastal Australia, but is absent in the northern areas. Western edge of its expected distribution is the Mt Lofty Ranges east of Adelaide. Found in a wide range of habitats but typically only present where there is reasonably thick undergrowth. It often makes a grumpy buzzing call but also sings a clear musical song.
Yap Cicadabird
Edolisoma nesiotis
Small cuckooshrike with a restricted range, found only on Yap, which is part of the larger Caroline Islands group in the Federated States of Micronesia. Males are mainly gray with black on the face, wing, and tail. Females brown on the back and rich buff below, with fine scaling. Seemingly only found in good forest. One frequent vocalization is an upslurred whistle. Distinctive within its small range.
