The white-browed gnatcatcher (Polioptila bilineata) is a species of bird in the gnatcatcher family Polioptilidae. It is native to central and South America.
This species was formerly considered a subspecies of the tropical gnatcatcher (Polioptila plumbea).
Taxonomy
The white-browed gnatcatcher was formally described in 1850 by the French naturalist Charles Lucien Bonaparte and given the binomial name Sylvia bilineata. Bonaparte specified the locality as Cartagena, a city on the Caribbean coast of Colombia.{{cite book | last=Bonaparte | first=Charles Lucien | author-link=Charles Lucien Bonaparte | year=1850 | title=Conspectus Generum Avium | volume=1 | language=Latin | publisher=E.J.
