Rare
Under 5% of wildlife watchers report a Vermiculated Screech-Owl sighting in Tortuguero National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 329th most-seen of the 348 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Vermiculated Screech-Owl in Tortuguero National Park 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 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.
15th of 16
Of the 16 parks where we can rate Vermiculated Screech-Owl sightings, Tortuguero National Park ranks 15th 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 Tortuguero National Park (9 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.
