Possible
About 30% of wildlife watchers report a Crevice Swift sighting in Reserva de la Biosfera Mariposa Monarca on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 6 reptiles we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
April and May
In those months about 60% of wildlife watchers report a Crevice Swift in Reserva de la Biosfera Mariposa Monarca on a given day, against under 5% in June and December–February, the lowest months. Those are among Reserva de la Biosfera Mariposa Monarca's driest months, with about 65 mm of rain a month against 270 mm in July.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Crevice Swift sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Crevice Swift sightings, Reserva de la Biosfera Mariposa Monarca has the highest daily chance: about 30%. Next come Cumbres de Monterrey National Park (Mexico, about 20%).
GBIF citizen-science records
It is estimated from how often the Crevice Swift is recorded against all the reptiles logged in Reserva de la Biosfera Mariposa Monarca (7 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.
