The northern parula (Setophaga americana) name Parula ultimately derives from Latin parus meaning titmouse. It breeds in eastern North America from southern Canada to Florida and is one of only a few birds that nest in Spanish moss. One of the smallest warblers, it was originally named the Blue Yellow-backed Warbler and also the Finch Creeper. Northern Parulas eat spiders and many kinds of insects, particularly caterpillars.
