Gouldian finch

The Gouldian finch Erythrura gouldiae, is endemic bird of the tropical savannah of northern Australia. The Gouldian is special in that it occurs sympatrically in three genetically distinct head colour morphs. This provides an excellent opportunity to understand the genetic basis of colour divergence in birds, and the processes underlying speciation and polymorphism.

In both the wild and captivity we are studying behaviour, genetics and physiology of this polymorphic species. We are also working with historical samples from museums to understand the extent to which this threatened species has declined over the past century.

Our molecular work on this species is being conducted in collaboration with Terry Burke (Sheffield University, UK) and Lee Ann Rollins (Deakin University).
