About These Birds
беркут
The golden eagle is one of the most powerful and agile raptors in the Northern Hemisphere. Revered by many cultures, it has been used in falconry for centuries, particularly by Kazakh eagle hunters of Central Asia. Golden eagles can dive at speeds exceeding 240 km/h when pursuing prey.
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
