The Yucatan poorwill (Nyctiphrynus yucatanicus) is a species of nightjar in the family Caprimulgidae. It is found in the Yucatán Peninsula of Belize, Guatemala, and Mexico. The Yucatan poorwill has sometimes been placed in genus Otophanes, which was later merged into the current Nyctiphrynus. It, the ocellated poorwill (N. ocellatus), and the eared poorwill (N. mcleodii) are sister species. Especially it and the eared poorwill are believed to be the closest living relatives due to the similarity in songs and plumage characteristics. The Yucatan poorwill is monotypic.
The Yucatan poorwill is 19.5 to 22 cm (7.7 to 8.7 in) long, making it the smallest species of nightjar in the Yucatán Peninsula. One male weighed 21.3 g (0.75 oz) and one female 27.7 g (0.98 oz). Both sexes have a brown morph; there is also a rufous morph that is much more prevalent among females. The former is mostly dark grayish brown with a variety of dusky, gray, and black vermiculation and streaks. Its face is dark sooty brown to brownish black with brown vermiculation. It has a faint buffy collar on its nape and a white patch on the throat. The underparts are brown... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yucatán Poorwill sighting in Calakmul Biosphere Reserve on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 253rd 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 Poorwill in Calakmul Biosphere Reserve on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Yucatán Poorwill sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 2 parks where we can rate Yucatán Poorwill sightings, Calakmul Biosphere Reserve ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Tikal National Park (Guatemala, under 5%).
GBIF citizen-science records
It is estimated from how often the Yucatán Poorwill is recorded against all the birds logged in Calakmul Biosphere Reserve (11 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.
