Red-winged Fairywren
Malurus elegans
The red-winged fairywren is 15 cm (6 in) long and weighs 8–11 g (0.28–0.39 oz), making it the largest of the fairywrens. The average tail length is 7.5 cm (3.0 in), among the longest in the genus. Averaging 10 mm (0.4 in) in males and 9.3 mm (0.4 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 by picking insects off of their environs. Voice: Vocal communication among red-winged fairywrens is used primarily for communication between birds in a social group and for advertising and defending a territory. They are able to distinguish different individuals on the basis of song alone, which is integral to the identification of group members and strangers.

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.
