With luck
About 10% of wildlife watchers report an Olive-sided Flycatcher sighting in Grand Teton National Park on a given day, based on 299 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 67th most-seen of the 185 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
June and July
In those months about 20% of wildlife watchers report an Olive-sided Flycatcher in Grand Teton National Park on a given day, against under 5% in February–May and September–November, the lowest months. Those are among Grand Teton National Park's driest months, with about 35 mm of rain a month against 85 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Olive-sided Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 73
Of the 73 parks where we can rate Olive-sided Flycatcher sightings, Grand Teton National Park ranks 5th at about 10%. The best odds are in Glacier National Park (United States, about 30%), Yosemite National Park (United States, about 20%) and Gros Morne National Park (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the Olive-sided Flycatcher is recorded against all the birds logged in Grand Teton National Park (299 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.
