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 →

GBIF citizen-science records
It is estimated from how often the Yellowish Flycatcher is recorded against all the birds logged in Monteverde Cloud Forest Reserve (4,283 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.
