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.
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.
