About These Birds
Common Nightingale
The common nightingale is celebrated as one of the finest songsters in the bird world, inspiring poets from Homer to Keats. Males sing complex phrases of over 250 different types, often at night during breeding season. Despite its famous song, the nightingale is a plain-looking bird that skulks in dense vegetation.
Diều ăn rắn
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.
