Male superb fairy-wrens are famous for their bright blue and black breeding feathers, while females and young birds are mostly brown with pale underparts and reddish-brown areas around the eyes.

These tiny birds are often seen hopping through low shrubs and leaf litter searching for insects. They usually move in family groups and flick their tails upright as they travel through dense vegetation. Superb fairy-wrens are common in parts of Sydney, including bushland areas around Field of Mars Reserve and Lane Cove National Park where there is thick understorey vegetation for shelter.

What is the life cycle of superb fairy-wrens?

Superb fairy-wrens breed mainly during spring and summer when food is more abundant. Females build small dome-shaped nests from grasses and spider webs in dense shrubs close to the ground. They usually lay two to four eggs, which hatch after about two weeks.
