The American gray flycatcher, American grey flycatcher, or just gray flycatcher (Empidonax wrightii) as it is known in North America, is a small, insectivorous passerine in the tyrant flycatcher family. It is common in the arid regions of western North America, especially the Great Basin. From sagebrush steppes to pinyon-juniper woodlands and ponderosa pine forests, this flycatcher forages for insects from shrubs or low tree branches.
The American gray flycatcher is one of the many species in the genus Empidonax. These species are very similar in appearance and behavior, and they are notoriously difficult to differentiate. The best characteristics for distinguishing these species are voice, breeding habitat, and range. The American gray flycatcher, however, can be identified by a unique behavior, its downward tail wag. Other Empidonax species typically exhibit a rapid upward tail flick.
American gray flycatchers are small birds, but larger than most Empidonax flycatchers. A typical adult measures 15 cm (5.9 in) in length, 22 cm (8.7 in) in wingspan, and 12.5 g (0.44 oz) in mass. Adults have pale gray upperparts, darker on the wings and tail, with a faint olive tinge... Wikipedia →

Possible
About 20% of wildlife watchers report a Gray Flycatcher sighting in Cabo Pulmo National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 38th most-seen of the 100 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.
October
In that month about 50% of wildlife watchers report a Gray Flycatcher in Cabo Pulmo National Park on a given day, against about 10% in January, March, May–June and September, the lowest months. July and August have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Gray 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.
Yes
Of the 12 parks where we can rate Gray Flycatcher sightings, Cabo Pulmo National Park has the highest daily chance: about 20%. Next come Guadalupe Mountains National Park (United States, about 10%) and Grand Canyon National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Gray Flycatcher is recorded against all the birds logged in Cabo Pulmo National Park (30 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.
