With luck
About 10% of wildlife watchers report a Vermiculated Screech-Owl sighting in Calakmul Biosphere Reserve on a given day, based on 53 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 153rd most-seen of the 271 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January–March and June–July
In those months about 10% of wildlife watchers report a Vermiculated Screech-Owl in Calakmul Biosphere Reserve on a given day, against under 5% in April–May and August–December, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Vermiculated Screech-Owl sightings with a recorded time, and about 6 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 16 parks where we can rate Vermiculated Screech-Owl sightings, Calakmul Biosphere Reserve ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Tikal National Park (Guatemala, about 10%).
Same family: Strigidae
The closest relatives of the Vermiculated Screech-Owl that you can see in Calakmul Biosphere Reserve (family Strigidae, Typical Owls) are Ferruginous Pygmy-Owl (about 20%) and Mottled Owl (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Vermiculated Screech-Owl is recorded against all the birds logged in Calakmul Biosphere Reserve (53 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.
