Sittellas are a family of small birds found in Australia and New Guinea. The family includes the Black Sittella (Daphoenositta miranda), the Varied Sittella (Daphoenositta chrysoptera), and the Papuan Sittella (Daphoenositta papuensis).

The Varied Sittella lives across much of mainland Australia. Different groups of these birds can look a little different, with patterns of white, black, and gray. They live mainly in eucalypt forests and woodlands.

Varied Sittellas climb along tree trunks and branches as they search for food. They often move downward while looking under bark and in small cracks for insects and other tiny animals. Because they move along trees in a way that is similar to nuthatches, they are sometimes called Australian Nuthatches.

The Black Sittella lives in the forests of New Guinea. It is mostly black and has a bright reddish face. Like other sittellas, it searches along tree trunks and branches for insects and other small animals.

The Papuan Sittella lives in mountain forests in New Guinea. It was once considered a type of Varied Sittella but is now recognized as a separate species by some modern classifications. Like other sittellas, it is a small, active bird that searches tree trunks and branches for insects and other tiny animals.
