Scrub Nightjar
Nyctidromus anthonyi
Brown-and-buff nightbird found in arid scrub and deserts in western Ecuador and northwestern Peru. It is dark brown, heavily mottled with buff, and has a white throat. In flight, it has white crescents near the wingtips and white stripes along the outer tail feathers. Similar to Common Pauraque, but smaller, with a shorter tail and a different voice. Compared to Tschudi's Nightjar, with which it overlaps in northwestern Peru, Scrub is much darker and has a different song. Scrub Nightjar typically gives a clear, whistled, incessantly repeated “tWEE-oh,” more emphatic and not as burry as Common Pauraque.
Identification
Male Anthony's nightjars weigh 32.3 to 39.5 g (1.1 to 1.4 oz) with a mean of about 35 g (1.2 oz) and females 31.0 to 42.0 g (1.1 to 1.5 oz) with a mean of about 37 g (1.3 oz). Males have grayish brown upperparts with buff speckles and blackish brown streaks; the crown is darker. They have a broad tawny buff collar on the nape. The tail feathers are mostly brown with considerable white on the outermost pair. The chin and upper throat are tawny buff with dark brown bars and speckles. The lower throat is white, the breast grayish brown with buff bars, and the belly and flanks buff with faint brown bars. In flight the five outermost primary wing feathers show a white or buffy stripe. The female is similar to the male but with less white on the wings and tail.
Taxonomy
Anthony's nightjar was originally described in genus Caprimulgus but DNA analysis and vocal differences show that it and its close relative the pauraque (Nyctidromus albicollis) require their own genus. For a time in the mid-1900s it was considered a subspecies of little nightjar (Setopagis parvula). Anthony's nightjar is monotypic.

Range and habitat

Other Birds
Black-and-red Broadbill
Cymbirhynchus macrorhynchos
Utterly unmistakable inhabitant of waterside and riverine lowland evergreen forests, mangroves, and plantations. Midnight black with long white slashes on each wing, wine-red underparts, and a black chinstrap. Bulbous bill is glowingly powder-blue with warm tinges of orange and greenish-yellow. During the breeding season, the pendulous nests of this species can be quite obvious, hanging over forested waterways. Voice is nasal and generally unpleasant-sounding, consisting of odd low mechanical rasps.
Saipan Reed Warbler
Acrocephalus hiwae
A relatively large plain brown reed warbler with a pale throat, a yellowish face, a darker cap and tail, and an absurdly long decurved bill. Found in areas of tall dense grasses, reed marshes, and scrubby thickets up to 400 meters of elevation. Song is a slow, loud reel of whistles, warbles, harsh “chak” notes, and trills. Call is a loud, offensive “tchak.” Often sings at night.
Angola Waxbill
Coccopygia bocagei
A tiny colorful seed-eating waxbill with a grayish breast, a yellow belly, an olive-green back finely barred with dark gray, and a scarlet rump and upper tail. The male has a black throat patch that the female lacks. A local West Angolan endemic. Pairs and small groups eat grass in open areas adjacent to forest and thickets. Vocalizations are undescribed, but the species probably gives calls similar to the plaintive “swee-swee” and “seeet” of the closely related Swee and Yellow-bellied Waxbills. No similar waxbills overlap in range.
