About These Birds
金雕
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.
Mallard
The mallard is the ancestor of most domestic duck breeds and the most abundant and widespread dabbling duck in the world. Males perform elaborate courtship displays including head-bobbing and whistle-grunt calls. Mallards are highly adaptable, thriving in both wilderness and urban environments.
