Possible
About 30% of wildlife watchers report a Crevice Swift sighting in Toluca on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 3rd most-seen of the 9 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.
May and September
In those months about 50% of wildlife watchers report a Crevice Swift in Toluca on a given day, against under 5% in June–July and December–January, the lowest months. Those are among Toluca's wettest months, with about 100 mm of rain a month against 5 mm in December.
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 4 cities where we can rate Crevice Swift sightings, Toluca has the highest daily chance: about 30%. Next come León (México, about 30%) and Mexico City (México, about 20%).
GBIF citizen-science records
It is estimated from how often the Crevice Swift is recorded against all the reptiles logged in Toluca (22 verified sightings), 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.
