These are brightly colored birds, with bright green upperparts and creamy underparts. They have short rounded wings, a long tail, strong legs, and a sharp bill with a curved tip to the upper mandible. They are wren-like with a long upright tail that is often moved around. The crown is rufous and the upperparts are predominantly olive green. Their underside is creamy white. The sexes are identical, except that the male has long central tail feathers in the breeding season, although the reliability of sexing data accompanying museum specimens used in determining this sexual dimorphism has been questioned. Young birds are duller. When calling, the dark patches on the sides of the neck become visible. These are due to the dark pigmented and bare skin that is present in both sexes and sometimes gives the appearance of a dark gorget.
