Rare
Under 5% of wildlife watchers report a Streak-backed Oriole sighting in Rincón de la Vieja National Park on a given day, based on 53 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 160th most-seen of the 341 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.

All parks ranked.
GBIF citizen-science records
It is estimated from how often the Streak-backed Oriole is recorded against all the birds logged in Rincón de la Vieja National Park (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.
