The blue-breasted fairywren, or blue-breasted wren, is a species of passerine bird in the Australasian wren family, Maluridae. It is non-migratory and endemic to southern Western Australia and the Eyre Peninsula in South Australia. Exhibiting a high degree of sexual dimorphism, the male adopts a brilliantly coloured breeding plumage, with a bright blue crown, ear coverts and upper back, red shoulders, contrasting with a dark blue throat, grey-brown tail and wings and pale underparts. Non-breeding males, females and juveniles have predominantly grey-brown plumage. No separate subspecies are recognised.
Region
Southwest and south-central Australia
Typical Environment
The blue-breasted fairywren inhabits dense shrublands, mallee, and heaths across southwestern Western Australia and the Eyre Peninsula of South Australia. It favors low, tangled vegetation that provides cover, including coastal thickets and inland sclerophyll scrub. Birds are typically found near patches of dense understory and avoid extensive open woodland. Populations can be patchy due to habitat fragmentation, but the species persists where suitable shrub cover remains.

This small, ground-hugging fairywren is endemic to southern Australia and is famed for the male’s striking breeding plumage with a vivid blue breast and rufous shoulders. Outside the breeding season, males molt into drab brown tones similar to females, a classic example of seasonal sexual dimorphism. They live in cooperative family groups with helpers assisting breeding pairs and often keep their tails cocked upright while foraging in dense scrub.
