Tweet of the Day is the voice of birds and our relationship with them, from around the world.

Liz Bonnin presents the displaying Raggiana bird-of-paradise from Papua New Guinea. An explosion of colour flashes across the tree canopy of a rainforest: male Raggiana birds-of-paradise, one of the most spectacularly coloured birds in the world, are displaying to one another. The Raggiana or Count Raggi's bird-of-paradise is Papua New Guinea's national bird and it's easy to see why. His yellow head and green throat are eye-catching enough but even more flamboyant are the long tufted flank feathers which he can raise into a fan of fine reddish-orange plumes. Males gather at traditional display sites quivering these enormous flaming plumes like cabaret dancers as they cling to an advantageous branch. The urgency of their display is underlined by frantic calls which echo through the canopy, in the hope he can impress the much plainer female to mate with him.
