Band-winged Nightjar

Identification

The band-winged nightjar is a medium-sized nightjar, measuring 20 to 27 cm in length. Its most distinctive feature—the source of its common name—is a bold band visible across the wing in flight: white in males, buff in females. The species exhibits considerable plumage variation across its range, but generally displays greyish-brown to brownish-orange upperparts with dense spotting on the wing-coverts. Males show white marks on the edges of their primary feathers and distinctive white bands on the tail, while females lack these white tail markings. Both sexes have a prominent pale band across the lower throat. The iris, bill, legs, and feet range from brown to blackish-brown.

Range & Habitat

This nightjar is widespread throughout South America, occurring in the Andes, Venezuelan Coastal Range, Santa Marta Mountains, and tepuis, as well as most of Chile, Argentina, Paraguay, Uruguay, and eastern Brazil. Eight subspecies are now recognized, reflecting the species' vast continental distribution. The band-winged nightjar is remarkably adaptable, thriving in diverse habitats ranging from the edges of humid montane forests to shrubby semi-deserts and even urban rooftops. This habitat flexibility has allowed it to maintain populations across dramatically different environments.

Behaviour & Diet

Like other nightjars, this species is primarily nocturnal and insectivorous, though detailed dietary information is limited. The band-winged nightjar is territorial and vocal, particularly during breeding season. Males produce a distinctive high-sharp whistle—rendered as "seeeeert sweeeert seeeet"—that is constantly repeated every 1 to 3 seconds at dusk and dawn. During the breeding season, males make high "cheet" calls in flight. Females produce a nasal "tchree-ee" sound when flushed. Fledglings develop rapidly, beginning short glides after approximately 12 days and becoming increasingly mobile thereafter.

Best Time & Places to See It

The band-winged nightjar can be encountered throughout its vast South American range during breeding season, when males are most vocal. Listen for their distinctive whistling calls at dusk and dawn in appropriate habitats. The species' presence across such diverse environments—from high-altitude Andean forests to lowland semi-deserts to urban areas—means it may be found in many different settings across South America. Dawn and dusk periods offer the best opportunities for observation, when the birds are most active and vocal.

Photography Tips

The band-winged nightjar's cryptic plumage makes it challenging to photograph perched on the ground or branches. However, the distinctive wing bands and tail markings are best captured in flight, so flight photography during dusk or dawn activity periods will showcase the species' most recognizable features. Males' white wing and tail markings provide good contrast for photography compared to females' buff markings. Patience and knowledge of the bird's vocalizations will help locate individuals for photography opportunities. The species' adaptability to urban rooftops may provide accessible locations for observation and photography in some areas.
