Physical characteristics

Grasswrens are cryptically colored shades of tan and brown with black-and-white markings, while fairy-wrens have breeding-plumaged males with bright blues, violets, purples, and russets; some species feature cheek patches of brilliant turquoise that can be extended to form a face fan during agonistic or nuptial displays. Long, cocked tails are displayed while moving and are characteristic of this family. Emu-wrens have long, filamentous tails, and like the other fairy-wrens are dimorphic in plumage. Grasswrens are nearly monomorphic in plumage, with subtle shades distinguishing the sexes: females are usually more russet below.
