About 10% of wildlife watchers report a Cinereous Tyrant sighting in El Impenetrable National Park on a given day, based on 41 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 118th most-seen of the 219 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.
April to August
In those months about 20% of wildlife watchers report a Cinereous Tyrant in El Impenetrable National Park on a given day, against under 5% in November, the lowest month. December has too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Cinereous Tyrant sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only El Impenetrable National Park, in our data
El Impenetrable National Park is the only park on Wallace's Line with enough records to rate Cinereous Tyrant sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Cinereous Tyrant is recorded against all the birds logged in El Impenetrable National Park (41 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.
