These birds seem to occur all over Northern Australia. They are hyperactive, noisy little guys with elaborate bowers. The purple plume on the back of their heads rises when they want to impress another bird.
The male builds a bower and decorates it with white and silver objects to impress the female. The female builds a nest elsewhere to lay her eggs.
This impressive bower was decorated with white snail shells, bits of broken glass and crumpled wads of silver foil. The males are incredibly fussy about the arrangement of the decoration around their bower. If you drop in an extra snail shell, the bird will quickly pick it up and remove it.
