The white-lored gnatcatcher (Polioptila albiloris) is a species of bird in the family Polioptilidae. It is found in Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. The white-lored gnatcatcher was previously considered conspecific with the black-capped gnatcatcher (Polioptila nigriceps). The Yucatan gnatcatcher (P. albiventris) was previously a treated as a subspecies of the white-lored. The white-lored gnatcatcher has two subspecies, the nominate Polioptila albiloris albiloris and P. a. vanrossemi.
The white-lored gnatcatcher is 11 to 12 cm (4.3 to 4.7 in) long and weighs 6 to 9 g (0.21 to 0.32 oz). The nominate male in breeding plumage has a black cap down to the eyes and including the nape. The rest of the upperparts are bluish gray. The tail is black with white outermost feathers. The throat is white becoming pale bluish gray on the breast and flanks. The female has a dark gray cap and the eponymous white lores and supercilium. The juvenile is similar to the female but has browner upperparts. The male P. a. vanrossemi has a larger black cap and longer wings and tail than the nominate. Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-lored Gnatcatcher is recorded against all the birds logged in Las Baulas Marine National Park (323 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.
