The tropical gnatcatcher (Polioptila plumbea) is a small active insectivorous songbird, which is a resident species throughout a large part of northern South America. It was formerly considered as conspecific with the white-browed gnatcatcher and the Marañón gnatcatcher.
The tropical gnatcatcher was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it in the genus Todus, coined the binomial name Todus plumbeus and specified the type locality as Suriname in South America. The specific epithet plumbeus is Latin meaning "plumbeous" or "lead-coloured". Gmelin based his account on the "Plumbeous tody" that had been described in 1782 by the English ornithologist John Latham in his book A General Synopsis of Birds. Latham had examined a specimen in the collection of the British Museum. The tropical gnatcatcher is now one of 17 gnatcatchers placed in the genus Polioptila that was introduced in 1855 by the English zoologist Philip Sclater.

GBIF citizen-science records
It is estimated from how often the Tropical Gnatcatcher is recorded against all the birds logged in João Pessoa (37 verified sightings), 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.
