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.
识别特征
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.
分类信息
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.
