The Yucatan nightjar (Antrostomus badius) is a species of nightjar in the family Caprimulgidae. It is found in Belize, Guatemala, Mexico, and Honduras. The Yucatan nightjar was for many years classified in genus Caprimulgus but was later restored to its original genus Antrostomus. It and the tawny-collared nightjar (A. salvini) were for a time considered subspecies of the silky-tailed nightjar (A. sericocaudatus). The Yucatan nightjar is monotypic.
The Yucatan nightjar is 24 to 25.5 cm (9.4 to 10 in) long. One male weighed 65.5 g (2.3 oz) and three females 51.2 to 64.3 g (1.8 to 2.3 oz). The male's upperparts are grayish brown. The crown has blackish brown spots and grayish white speckles, and the back and rump have buff and cinnamon speckles and broad blackish brown streaks. It has a broad tawny or buff collar on the nape and the sides of the neck.

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 →

With luck
About 10% of wildlife watchers report a Yucatán Nightjar sighting in Ría Lagartos Biosphere Reserve on a given day, based on 78 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 86th most-seen of the 216 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
May and October
In those months about 20% of wildlife watchers report a Yucatán Nightjar in Ría Lagartos Biosphere Reserve on a given day, against under 5% in April, June–September and November–December, the lowest months.
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.
Yes
Of the 4 parks where we can rate Yucatán Nightjar sightings, Ría Lagartos Biosphere Reserve has the highest daily chance: about 10%. Next come Calakmul Biosphere Reserve (Mexico, under 5%) and Celestún Biosphere Reserve (Mexico, under 5%).
GBIF citizen-science records
It is estimated from how often the Yucatán Nightjar is recorded against all the birds logged in Ría Lagartos Biosphere Reserve (78 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.
