The Eclectus Roratus parrot has extreme sexual dimorphism in the colours of the plumage.
The male is mostly bright green with a yellow-tinge on the head. It has blue primaries, and red flanks and underwing coverts. Its tail is edged with a narrow band of creamy yellow, and is dark grey edged with creamy yellow underneath, and the tail feathers are green centrally and more blue as they get towards the edges.
The upper mandible of the adult male is orange at the base fading to a yellow towards the tip, and the lower mandible is black. Adults have yellow to orange irises and juveniles have dark brown to black irises.
