Superb fairy-wren

This beautiful bird is an aptly named Superb fairy-wren. The small, superb fairy-wren is endemic to eastern Australia. Males are easily distinguished from females by their distinctive colorings: mostly blue, with a black band across their back and head. This blue turns iridescent when the male is looking for a mate. Superb fairy-wren dads sing to their eggs to get more attentive chicks, and Superb fairy-wrens are adjusting their egg sizes for climate. They can strategically alter the size of their laid eggs to help chicks survive in harsher conditions.
