Sand-colored Nighthawk

Identification

The Sand-colored Nighthawk is a small nightjar measuring 20.5 to 22 cm in length. True to its name, it displays pale grayish-brown upperparts heavily marked with darker brown streaks, bars, and spots. The throat is distinctively white to buffy white, while the breast is grayish white with a cinnamon tinge and brown barring. The belly is white with brown spotting on its upper portion, and the underwings are predominantly white—a useful field mark when observed in flight. These subtle, cryptic plumage patterns provide excellent camouflage on the sandy and rocky substrates where the bird spends its daylight hours.

Range & Habitat

This species inhabits the western Amazon basin across a vast range spanning Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. The nominate subspecies occupies northwestern Amazonia from southeastern Colombia and southwestern Venezuela through northeastern Peru to northwestern Brazil, with populations also occurring along river corridors in eastern Ecuador and northern Bolivia. The subspecies C. r. xylostictus is restricted to Colombia's Cundinamarca Department. The Sand-colored Nighthawk shows a strong preference for waterside habitats, primarily along major watercourses but also utilizing oxbow lakes and grassy clearings such as airstrips, rarely venturing above 500 meters elevation.

Behaviour & Diet

Crepuscular and nocturnal by nature, this nighthawk roosts during daylight hours on river islands and sandbars, frequently congregating in large numbers. When water levels rise seasonally, birds shift to tree branches overhanging the water. The Sand-colored Nighthawk forages actively at dusk and intermittently through the night, pursuing an entirely insectivorous diet. Its flight style is notably distinctive among nightjars—less erratic than most congeners, with an oddly mechanical flapping motion reminiscent of terns rather than the typical buoyant, erratic flight of other nightjar species.

Best Time & Places to See It

Breeding occurs from May through August in southeastern Peru and June through September in central Brazil, though the season remains undocumented elsewhere in its range. The species nests in loose colonies, often in proximity to colonies of Yellow-billed Terns, Large-billed Terns, and Black Skimmers, laying two eggs in simple scrapes on sandbars. Observers should focus their efforts on major river systems and associated waterside clearings throughout the western Amazon basin during these breeding periods for the best chance of encountering this species.

Photography Tips

The Sand-colored Nighthawk's cryptic plumage makes daylight photography challenging; positioning yourself near known roosting sites on sandbars at dawn or dusk offers the best opportunities. The bird's white throat and underwings provide useful compositional highlights. Early morning and late afternoon light are ideal for capturing the subtle plumage details and the characteristic pale coloration that gives this species its common name. Patience and a sturdy tripod are essential, as birds may remain motionless for extended periods while roosting.
