About These Birds

American Robin

The American robin is widely regarded as a harbinger of spring across North America. Despite its name, it is a true thrush unrelated to the European robin. American robins produce two to three broods per year and are among the earliest birds to sing in the morning chorus.

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.
