With luck
About 10% of wildlife watchers report a Black-striped Sparrow sighting in Tortuguero National Park on a given day, based on 316 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 100th most-seen of the 348 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April and June
In those months about 20% of wildlife watchers report a Black-striped Sparrow in Tortuguero National Park on a given day, against under 5% in September–October and December, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Black-striped Sparrow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 26
Of the 26 parks where we can rate Black-striped Sparrow sightings, Tortuguero National Park ranks 11th at about 10%. The best odds are in Piedras Blancas National Park (Costa Rica, about 50%), Arenal Volcano National Park (Costa Rica, about 40%) and Chagres National Park (Panama, about 20%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Black-striped Sparrow is recorded against all the birds logged in Tortuguero National Park (316 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.
