Maluridae

Maluridae is a family of small, insectivorous passerine birds endemic to Australia and New Guinea. 
Commonly known as 'wrens', they are unrelated to the true wrens of the Northern Hemisphere. The family includes 15 species of fairywren, 3 emu-wrens, and 11 grasswrens. There are six genera.
The Maluridae are one of the many bird families to have evolved from a great adaptive radiation of what were crows to new ecological opportunities in Australasia. Their closest relatives are the Meliphagidae (honeyeaters), and the Pardalotidae. 
Their obvious similarity to the wrens of Europe and America is not genetic, but simply the consequence of convergent evolution between more-or-less unrelated species that share the same ecological niche.
Their behaviour is similar to many other passerine families. The males defend territory and attract females by song and bright coloured plumage. Females are a dowdy brownish colour, better for camouflage. The males' colour is much less bright out of season. They are insectivorous, and nest in dense undergrowth. The parallels with Eurasian wrens are quite striking.
