A small bird with a long blue tail that is held cocked. Breeding males are almost entirely blue with a strong black line from the bill through the eyes and around the back of the head, a black chest band, and a black rump. Nonbreeding males are fairly plain grayish-brown birds with black bills, bright blue tails, and some blue in the folded wing. Females are tan above with a duller blue tail and a reddish bill. Note that the patch between the eye and bill (lores) on females is a fraction paler than the bill (in Variegated Fairywren the lores are much darker than the bill). This species is fairly common in arid inland Australia, as well as in southwest Western Australia.
