Gibberbird

The gibberbird (Ashbyia lovensis) is a species of chat within the Meliphagidae family of passerine birds.

The gibberbird has a distinctive visage which is characterized by a grey crown, yellow forehead, face and underbelly with a black to grey-brown rump. The bill is a dark brown to black with grey-brown feet. The iris of the eye is a distinguishing shade of bright yellow.

Unlike other chats, the gibberbird only has slight sexual dimorphisms between the male and female. Females differ very slightly and can sometimes be distinguished by more brown plumage, especially around the throat, face and neck. They can also have a heavier breast band and a generally duller appearance in comparison to the males.

Juveniles appear similar to adults, with a brown back, crown and wings, and a pale yellow throat.

The gibberbird is monomorphic in terms of length and weight. Generic measurements have been found to range from 12.5 to 13 cm (4.9 to 5.1 in) in length and 14 to 20 g (0.49 to 0.71 oz) in weight.
