Purple-backed Fairywren
Malurus assimilis
The purple-backed fairywren is on average 14.5 cm (5.5 in) long. 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 and blue-purple crown and forehead, a black throat and nape, a blue-purple upper back, chestnut shoulders and a bluish-grey tail. The wings are drab brown and the belly white.

White-winged Fairywren
Malurus leucopterus
Measuring 11 to 13.5 centimetres (4.3 to 5.3 in) in length, white-winged fairywrens are one of the two smallest species of Malurus. Males typically weigh between 7.2 and 10.9 grams (0.25 and 0.38 oz) while females weigh between 6.8 and 11 grams (0.24 and 0.39 oz). Averaging 8.5 mm (0.3 in) in males and 8.4 mm (0.3 in) in females, 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: In 1980, Tideman characterised five different patterns of calls among Malurus leucopterus leuconotus; these were recognised by Pruett and Jones among the island subspecies M. l. edouardi. The main call is a reel made by both sexes in order to establish territory and unify the group. It is a long song of "rising and falling notes" that is first signaled by 3–5 chip notes.
