Splendid Fairywren
Malurus splendens
The splendid fairywren is a small, long-tailed bird 14 cm (5.5 in) long. Exhibiting a high degree of sexual dimorphism, the breeding male is distinctive with a bright blue forehead and ear coverts, a violet throat, and deeper rich blue back wings, chest, and tail with a black bill, eye band, and chest band. The blue breeding plumage of the male is often referred to as nuptial plumage. The non-breeding male is brown with blue in the wings and a bluish tail. The female resembles the non-breeding male but has a chestnut bill and eye-patch.

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.
