About These Birds
Greater Flamingo
The greater flamingo is the most widespread flamingo species and one of the most recognizable birds in the world. Their pink color comes entirely from carotenoid pigments in their crustacean and algal diet. Flamingos are social birds that breed in enormous colonies sometimes numbering tens of thousands.
ヘビクイワシ
The secretary bird is the only raptor that hunts primarily on foot, striding through grasslands on crane-like legs up to 1.2 meters tall. Its name may derive from the crest feathers resembling quill pens tucked behind a secretary's ear. The species is classified as Endangered due to habitat loss and decline across much of its range.
