Appearance
Peruvian Racket-tails have pronounced sexual dimorphism. Only the male has elongated racket-shaped outer rectrices that are about 7 to 7.5 cm long. These tail feathers have bare shafts with long terminal oval shaped flags that have blunted ends. In perching birds, the rackets are held parallel with a slight overlap of the flags. Both sexes are shining green above with a small white postocular spot. The underparts of the male are also shining green with an iridescent green throat patch that can be seen in good light. The female has white underparts with many large dark green spots, and its black tail has white tips. Both sexes have cinnamon colored leg puffs, although the male's are longer and fluffier.References:
