Eggs (Guide)
2; plain white; oval; about 71 x 53 mm. Incubation: about 42 days; mainly by female, but male relieves for periods during the day.
Young
Semi-altricial, nidifugous. Fledge in 63 - 70 days.
Subspecies
Sanford's Sea-eagle (Haliaeetus sanfordi) is retained as a species in contrast to Debus (2006), who proposed on the basis of molecular work, that sanfordi be treated as a subspecies of White-bellied Fish-Eagle (Haliaeetus leucogaster). The BirdLife Taxonomic Working Group consider the considerable differences in morphology, size and proportion, as indicated by Ferguson-Lees and Christie (2001), argue in favour of retaining sanfordi as a full species.
Similar Species
