Variegated Fairywren

Overview

The variegated fairywren (Malurus lamberti) is a fairywren that lives in eastern Australia. As a species that exhibits sexual dimorphism, the brightly coloured breeding male has chestnut shoulders and azure crown and ear coverts, while non-breeding males, females and juveniles have predominantly grey-brown plumage, although females of two subspecies have mainly blue-grey plumage.
Like other fairywrens, the variegated fairywren is a cooperative breeding species, with small groups of birds maintaining and defending small territories year-round. Groups consist of a socially monogamous pair with several helper birds who assist in raising the young.
