Western parotia: known for its 6 head wires & ballerina-like “tutu” of stiff feathers. Male parotias flash their iridescent breast feathers as they display for females. Each male clears a patch of forest floor several feet across, creating a stage where he performs a bizarre dance: hopping, prancing sideways, curtsying, & bobbing his head. Photo: Tim Laman
