About These Birds
นกอินทรีฮาร์ปี
The harpy eagle is among the most powerful raptors in the world, with talons as large as a grizzly bear's claws. It is the national bird of Panama. Deforestation poses the greatest threat to this species, as each breeding pair requires a vast territory of undisturbed forest.
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.
