Superb Fairywren
Malurus cyaneus
The superb fairywren is 14 cm (5+1⁄2 in) long and weighs 8–13 g (0.28–0.46 oz), with males on average slightly larger than females. The average tail length is 5.9 cm (2+1⁄3 in), among the shortest in the genus. Averaging 9 mm (0.4 in) in subspecies cyaneus and 8 mm (0.3 in) in subspecies cyanochlamys, the bill is relatively long, narrow and pointed and wider at the base. Wider than it is deep, the bill is similar in shape to those of other birds that feed by probing for or picking insects off their environs. Voice: Vocal communication among superb fairywrens is used primarily for communication between birds in a social group and for advertising and mobbing, or defending a territory. The basic, or Type I, song is a 1–4 second high-pitched reel consisting of 10–20 short elements per second; it is sung by both males and females.

Variegated Fairywren
Malurus lamberti
The variegated fairywren is 14–15 cm (5.5–6 in) long and weighs 6–11 g (0.21–0.39 oz). Like other fairywrens, it is notable for its marked sexual dimorphism, males adopting a highly visible breeding plumage of brilliant iridescent blue and chestnut contrasting with black and grey-brown. The brightly coloured crown and ear tufts are prominently featured in breeding displays. The male in breeding plumage has striking bright blue ear coverts, with the crown often slightly darker, a black throat and nape, a royal blue upper back, chestnut shoulders and a bluish-grey tail. Voice: Vocal communication among variegated fairywrens is used primarily for communication between birds in a social group and for advertising and defending a territory. The basic song type is a high-pitched reel of a large number of short elements (10–20 per second); this lasts 1–4 seconds. The reel of the variegated fairywren is the softest of all malurids.
