With luck
About 10% of wildlife watchers report a Grey-chested Jungle Flycatcher sighting in Gunung Leuser National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 56th most-seen of the 166 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Grey-chested Jungle Flycatcher sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Grey-chested Jungle Flycatcher is recorded against all the birds logged in Gunung Leuser National Park (27 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.
