The tawny-collared nightjar (Antrostomus salvini) is a species of nightjar in the family Caprimulgidae. It is endemic to Mexico. The tawny-collared nightjar was originally described as Caprimulgus salvini; Antrostomus was later split as a separate genus. It and the Yucatan nightjar (A. badius) were for a time considered subspecies of the silky-tailed nightjar (A. sericocaudatus). The tawny-collared nightjar is monotypic.
The tawny-collared nightjar is 23 to 25.5 cm (9.1 to 10 in) long. One female weighed 56 g (2.0 oz). The male's upperparts are blackish brown; the crown has blackish spots and the back and rump have fine light brown speckles and broad blackish streaks. It has a broad tawny or buff collar on the nape and the sides of the neck that give the species its name. The tail is also dark brown and the three outermost pairs of feathers have wide white tips. The wings are brown to blackish brown with tawny spots and bars. The face is dark reddish with brown barring. The chin and throat are blackish brown with a narrow white band below the latter, the breast blackish brown with cinnamon speckles, and the belly and flanks blackish brown... Wikipedia →

Rare
Under 5% of wildlife watchers report a Tawny-collared Nightjar sighting in Cumbres de Monterrey National Park on a given day, based on 50 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 152nd most-seen of the 275 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and August
In those months about 10% of wildlife watchers report a Tawny-collared Nightjar in Cumbres de Monterrey National Park on a given day, against under 5% in June–July and September–April, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Tawny-collared Nightjar sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Cumbres de Monterrey National Park, in our data
Cumbres de Monterrey National Park is the only park on Wallace's Line with enough records to rate Tawny-collared Nightjar sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Tawny-collared Nightjar is recorded against all the birds logged in Cumbres de Monterrey National Park (50 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.
