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.
Demoiselle Crane
The demoiselle crane is the smallest crane species but undertakes one of the most grueling migrations, crossing the Himalayas at altitudes over 8,000 meters to reach wintering grounds in India. Named for its elegant appearance by Marie Antoinette, it is the second most abundant crane species in the world.
