Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. Songbirds include three species of chickadee, two kinglets, several thrushes, warblers, sparrows, and finches. Wooded habitats shelter ruby-crowned kinglets and white-eyed vireos. The kinglets and "crests" are a small family of birds which resemble some warblers. The kinglets are a small family of birds which resemble the titmice.
