About These Birds
Downy Woodpecker
The downy woodpecker is the smallest and most widespread woodpecker in North America. Its small size allows it to forage on thin branches and weed stems that larger woodpeckers cannot access. Downies often join mixed-species flocks in winter, benefiting from the extra vigilance of multiple species watching for predators.
イヌワシ
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.
