The sand-colored nighthawk (Chordeiles rupestris) is a species of nightjar in the family Caprimulgidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela. Major taxonomic systems recognize two subspecies of sand-colored nighthawk, the nominate Chordeiles rupestris rupestris and C. r. xylostictus. However, at least two authors contend it is better treated as monotypic.
The sand-colored nighthawk is 20.5 to 22 cm (8.1 to 8.7 in) long. Its upperparts are pale grayish brown with darker brown streaks, bars, and spots. The chin and throat are white to buffy white, the breast grayish white with a cinnamon tinge and brown bars and spots, and the belly white with brown spots on its upper part. The underside of the wing is also mostly white.
The nominate subspecies of sand-colored nighthawk is found widely in northwestern Amazonia of southeastern Colombia, southwestern Venezuela, northeastern Peru, and northwestern Brazil. It is also found more narrowly along river corridors in eastern Ecuador, Peru, northern Bolivia, and western Brazil. C. r. xylostictus is found only in Colombia's Cundinamarca... Wikipedia →

Rare
Under 5% of wildlife watchers report a Sand-colored Nighthawk sighting in Yasuní National Park on a given day, based on 83 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 360th most-seen of the 533 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
April
In that month about 10% of wildlife watchers report a Sand-colored Nighthawk in Yasuní National Park on a given day, against under 5% in May to March, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Sand-colored Nighthawk sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 6
Of the 6 parks where we can rate Sand-colored Nighthawk sightings, Yasuní National Park ranks 4th at under 5%. The best odds are in Manu National Park (Peru, about 10%), Tambopata National Reserve (Peru, about 10%) and Cuyabeno Wildlife Reserve (Ecuador, under 5%).
GBIF citizen-science records
It is estimated from how often the Sand-colored Nighthawk is recorded against all the birds logged in Yasuní National Park (83 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
