The white-browed chat-tyrant has these six subspecies: During much of the first half of the twentieth century, what is now the Piura chat-tyrant (O. piurae) was considered an additional subspecies, and at least one publication suggests that it should return to that status. The white-browed and Piura chat-tyrants form a superspecies. In addition, it has been suggested that urubambae be merged into interior.

Possible
About 20% of wildlife watchers report a White-browed Chat-Tyrant sighting in Lauca National Park on a given day, based on 156 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 56th most-seen of the 112 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May and August
In those months about 40% of wildlife watchers report a White-browed Chat-Tyrant in Lauca National Park on a given day, against about 10% in January–March and November, the lowest months. Those are among Lauca National Park's driest months, with almost no rain against 150 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most White-browed Chat-Tyrant sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Lauca National Park, in our data
Lauca National Park is the only park on Wallace's Line with enough records to rate White-browed Chat-Tyrant sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the White-browed Chat-Tyrant is recorded against all the birds logged in Lauca National Park (156 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.
