Rare
Under 5% of wildlife watchers report a Bicolored Wren sighting in Darién National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 355th most-seen of the 397 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Bicolored Wren in Darién National Park on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Bicolored Wren is recorded against all the birds logged in Darién National Park (10 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.
