The yellowish flycatcher (Empidonax flavescens) is a small passerine bird in the family Tyrannidae, the tyrant flycatchers. It is found from Mexico to Panama. From the late 1800s to the 1980s the yellowish flycatcher was treated as conspecific with what was then (and is now again) the western flycatcher (E. difficilis). Subspecies E. f. salvini was originally described as a full species and some authors have suggested that it again be treated that way.
The yellowish flycatcher is 12.5 to 14 cm (4.9 to 5.5 in) long and weighs 9 to 16 g (0.32 to 0.56 oz). The sexes are alike. Adults of the nominate subspecies have a pale yellow almond-shaped eye-ring on an otherwise yellowish green face. Their crown, nape, and upperparts are olive-green. Their tail is dusky to blackish with yellowish green edges on the feathers. Their remiges are mostly dusky to blackish and glossy. Their primaries have pale olive edges and the secondaries and tertials have pale yellow edges to the outer webs... Wikipedia →

Possible
About 20% of wildlife watchers report a Yellowish Flycatcher sighting in La Tigra National Park on a given day, based on 99 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 21st most-seen of the 176 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellowish 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.

GBIF citizen-science records
It is estimated from how often the Yellowish Flycatcher is recorded against all the birds logged in La Tigra National Park (99 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.
