This small, skulking passerine measures approximately 12.5-13.5 cm in length with a wingspan of 15-19 cm and weighs a mere 10-15 grams, making it one of the more diminutive warblers.

It spends most of its time creeping and clambering through dense vegetation, rarely perching in the open, and roosts deep within protective cover. Foraging invo...
