The Philippine eagle (Pithecophaga jefferyi) is considered the largest of the extant eagles in the world in terms of length and wing surface. It is typically reported as measuring 86–102 cm (2 ft 10 in–3 ft 4 in) in total length. It also has a wingspan of 184 to 220 cm (6 ft 0 in to 7 ft 3 in).
But, in terms of weight and bulk, Steller’s sea eagle (Haliaeetus pelagicus), the Harpy eagle (Harpia harpyja) and the Martial eagle (Polemaetus bellicosus) are bigger than the Philippine eagle. Photo: blog.nus.edu.sg
