PASSERIFORMES: Meliphagidae
Ashbyia lovensis
The Gibberbird was once known as the Desert Chat.
There may be lots of Gibberbirds out there but I haven't found photographing them an easy task.
While ther may be a lot of them, there aren't many to the square kilometre of gibber, and when a little bird is spotted, it's usually a pipit, or perhaps a chat.
