High Quality Content by WIKIPEDIA articles! The Guianan Gnatcatcher (Polioptila guianensis) is a species of bird in the Polioptilidae family. It is found in the canopy in the Amazon Rainforest. The 15-20 species of small passerine birds in the gnatcatcher family occur in North and South America (except far south and high Andean regions). Most species of this mainly tropical and subtropical group are resident, but the Blue-gray Gnatcatcher of the USA and southern Canada migrates south in winter. They are close relatives of the wrens.
