Possible
About 20% of wildlife watchers report a Square-tailed Sawwing sighting in Taï National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 23rd most-seen of the 74 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 80%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Square-tailed Sawwing is recorded against all the birds logged in Taï 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.
