Rare
Under 5% of wildlife watchers report a Vermiculated Screech-Owl sighting in Cabo Blanco Absolute Nature Reserve on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 179th most-seen of the 241 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
January
In that month about 10% of wildlife watchers report a Vermiculated Screech-Owl in Cabo Blanco Absolute Nature Reserve on a given day, against under 5% in February to December, the lowest months. That is one of Cabo Blanco Absolute Nature Reserve's driest months, with about 40 mm of rain against 560 mm in October.
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.
6th of 16
Of the 16 parks where we can rate Vermiculated Screech-Owl sightings, Cabo Blanco Absolute Nature Reserve ranks 6th at under 5%. The best odds are in Tikal National Park (Guatemala, about 10%), Calakmul Biosphere Reserve (Mexico, about 10%) and Cañón del Sumidero National Park (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the Vermiculated Screech-Owl is recorded against all the birds logged in Cabo Blanco Absolute Nature Reserve (23 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.
