The Australo-Papuan babblers are medium-sized terrestrial birds with sombre plumage
and long decurved bills
. They range in size from 17–27 cm (7–11 in) in length and 30-85 g (1-3 oz) in weight. The wings are short and round, and the tail is long and often held fanned which makes it look broad as well. The feet and legs are strong and adapted to a terrestrial existence. There is no sexual dimorphism
in the plumage, which is composed of brown, russet and grey colours, with all but the Papuan Babbler
having striking white markings on the face and throat. The plumage of juvenile birds is similar to that of adults.
