Rare
Under 5% of wildlife watchers report a Sage Thrasher sighting in Grand Teton National Park on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 143rd most-seen of the 185 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Sage Thrasher in Grand Teton National Park on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Sage Thrasher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 13
Of the 13 parks where we can rate Sage Thrasher sightings, Grand Teton National Park ranks 8th at under 5%. The best odds are in Guadalupe Mountains National Park (United States, about 10%), Death Valley National Park (United States, under 5%) and Joshua Tree National Park (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Sage Thrasher is recorded against all the birds logged in Grand Teton National Park (29 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.
