Rare
Under 5% of wildlife watchers report a Gray-bellied Shrike-Tyrant sighting in Lauca National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 100th most-seen of the 112 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Gray-bellied Shrike-Tyrant in Lauca National Park on a given day, against under 5% in September to July, the lowest months. That is one of Lauca National Park's driest months, with almost no rain against 150 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Gray-bellied Shrike-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.
3rd of 3
Of the 3 parks where we can rate Gray-bellied Shrike-Tyrant sightings, Lauca National Park ranks 3rd at under 5%. The best odds are in Península Valdés (Argentina, about 20%) and Torres del Paine National Park (Chile, under 5%).
GBIF citizen-science records
It is estimated from how often the Gray-bellied Shrike-Tyrant is recorded against all the birds logged in Lauca National Park (17 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.
