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 →

With luck
About 10% of wildlife watchers report a Sand-colored Nighthawk sighting in Manu National Park on a given day, based on 455 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 166th most-seen of the 641 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Sand-colored Nighthawk in Manu National Park on a given day, against under 5% in March–April and June, the lowest months. That is one of Manu National Park's driest months, with about 70 mm of rain against 290 mm in February.
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.
Yes
Of the 6 parks where we can rate Sand-colored Nighthawk sightings, Manu National Park has the highest daily chance: about 10%. Next come 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 Manu National Park (455 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.
