アメリカ自然史博物館さんのインスタグラム写真 - (アメリカ自然史博物館Instagram)「Feeling as colorful as the Red-fan Parrot (Deroptyus accipitrinus) this weekend? Native to the tropical forests of South America, this parrot can be seen resting on branches high in the treetops with a group of four to 20 individuals. When threatened, it fans out its vibrant neck feathers, this species' speciality. These are also used in courtship rituals, when they’re raised up as come-hither collars by males and females in a display where a pair will sway their heads from side to side.
