About These Birds
European Robin
The European robin is one of the most beloved birds in Britain, where it is the unofficial national bird. Despite its friendly demeanor toward humans, robins are fiercely territorial against their own kind, singing year-round to defend territory. Their distinctive song is one of the first to be heard at dawn.
นกเลขานุการ
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.
