Pauraque

Identification

The pauraque is a medium-sized nightjar measuring 8.7–11 inches (22–28 cm) long. It exhibits two colour morphs with variegated plumage ranging from greyish-brown to rufous-brown. The species is notably long-tailed with broad rounded wings, and features a distinctive buff 'eye-ring' and 'facial stripe' that contrast with reddish sides to the face. Sexual dimorphism is apparent in wing and tail markings: adult males display a white band near the wing tips and mainly white outer tail feathers, while females show a narrower wing band and more restricted white tail markings. Subspecies vary in size and the degree of greyness in their plumage.

Range & Habitat

The pauraque breeds throughout subtropical and tropical regions of the New World, with its range extending from southern Texas to the lower Paraná River region. Most populations are year-round residents, though northern breeders in the United States may winter in eastern Mexico. The southernmost subspecies ranges through central and southern Brazil, Bolivia, Paraguay, and into Argentina, with populations becoming patchily distributed at the southern limits of the species' range.

This adaptable species inhabits open woodlands and grasslands, scrubland, and crop fields. Notably, it prefers mixed habitats offering both densely vegetated areas—ideally forest—for daytime shelter and open landscapes for nocturnal hunting. The pauraque is more terrestrial than most nightjars, possessing relatively long legs with bare tarsi, and frequently rests on roads and tracks. The species has benefitted from limited deforestation, as logging creates secondary growth habitats ideal for hunting, though it avoids heavily built-up or clear-cut areas.

Behaviour & Diet

True to its family, the pauraque is strictly nocturnal, becoming active at dusk. Like other nightjars, it feeds on insects caught in flight, typically by flycatching from low perches or by foraging over open ground. The species is known for its distinctive vocalizations: the male's song is highly variable, including a whistled "weeeow wheeooo" (described as "who-r-you"), soft puk puk calls, and a whip sound delivered during courtship flights as he flutters around the female. The female responds with rapid succession of whip sounds.

Breeding pairs produce two elongated, elliptical pinkish eggs placed directly on bare ground or leaf litter, sometimes only a single egg. If disturbed on the ground, the pauraque may run rather than fly—an unusual behaviour for a nightjar—reflecting its comparatively terrestrial lifestyle.

Best Time & Places to See It

The pauraque is a year-round resident throughout most of its range, making it accessible to travellers at any season. The species is most active from dusk onwards, so evening hours offer the best viewing opportunities. Look for it in open woodlands, grasslands, scrubland, and agricultural areas with nearby forest cover. Roads and tracks cutting through appropriate habitat are particularly productive, as the birds frequently rest on these open surfaces. The species' adaptability to human-modified landscapes means it can be found even in areas of secondary growth resulting from selective logging or clearing.

Photography Tips

Photographing the pauraque presents challenges typical of nocturnal species. Early dusk and pre-dawn hours provide the best natural light for photography while the bird remains active. Look for individuals resting on roads and open ground during these periods, when lighting is most manageable. The bird's distinctive white wing and tail markings in males—contrasting with its variegated brown plumage—provide useful visual targets when scanning open ground at dusk. A headlamp with a red filter may help locate roosting birds without causing disturbance. Use fast film speeds or high ISO settings to compensate for low-light conditions, and be prepared for the bird's tendency to run rather than immediately flush, which may allow closer approach than expected from a typical nightjar.
