Crombec Norteño Sylvietta brachyura

A small and virtually tailless warbler with a gray-brown back and rufous underparts. There is some geographical variation; the throat can be dull rufous, dull white, or bright white. Always shows a gray-brown eye-line. Found in a wide variety of savanna and woodland habitats. Similar to Red-faced Crombec, but has a strong eye-line, and in the area of overlap, usually shows a bright white throat. The song is a quick, jumbled whistled phrase that varies somewhat across the range. The call is a rapid wooden trill.
