Steller's sea eagle
The Philippine eagle is considered the largest of the extant eagles in the world in terms of length and wing surface, with only Steller's sea eagle and the harpy eagle being larger in terms of weight and bulk. Among the rarest and most powerful birds in the world, it has been declared the Philippine national bird. It is critically endangered, mainly due to massive loss of habitat resulting from deforestation in most of its range. Killing a Philippine eagle is punishable under Philippine law by up to 12 years in prison and heavy fines.
