About These Birds
águia-real
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.
Ruby-throated Hummingbird
The ruby-throated hummingbird is the only breeding hummingbird in eastern North America. These tiny birds beat their wings about 53 times per second and can fly backwards, sideways, and even briefly upside down. They make an extraordinary non-stop 800 km crossing of the Gulf of Mexico during migration.
