About These Birds
Common Ostrich
The common ostrich is the world's largest living bird, standing up to 2.7 meters tall and weighing up to 145 kg. Despite being flightless, it is the fastest bird on land, sprinting at speeds up to 70 km/h. Ostrich eggs are the largest of any living bird, weighing about 1.4 kg each.
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.
