About 20% of wildlife watchers report a Rufous-naped Ground-Tyrant sighting in Lauca National Park on a given day, based on 170 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 57th 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.
July
In that month about 40% of wildlife watchers report a Rufous-naped Ground-Tyrant in Lauca National Park on a given day, against about 10% in January, April and November, the lowest months. That is one of Lauca National Park's driest months, with about 5 mm of rain against 150 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Rufous-naped Ground-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 Rufous-naped Ground-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 Rufous-naped Ground-Tyrant is recorded against all the birds logged in Lauca National Park (170 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.
