The wings are brown to grayish brown with tawny spots and bars. The face is tawny with blackish brown speckles. The chin and throat... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yucatán Nightjar sighting in Calakmul Biosphere Reserve on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 267th most-seen of the 271 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yucatán Nightjar in Calakmul Biosphere Reserve on a given day, so our monthly data shows no clear season.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Yucatán Nightjar sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 4
Of the 4 parks where we can rate Yucatán Nightjar sightings, Calakmul Biosphere Reserve ranks 2nd at under 5%. The best odds are in Ría Lagartos Biosphere Reserve (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the Yucatán Nightjar is recorded against all the birds logged in Calakmul Biosphere Reserve (8 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.
