This species is classified as Vulnerable on the basis of a small estimated population which is suspected to be declining. It is judged to have distinct subpopulations, some totalling more than 250 birds. If subpopulations are found to be smaller or, conversely, that movement of birds between them means that all birds are in a single population, the species would warrant uplisting to Endangered.

70-90 cm. Only large eagle in the Solomons. Plain or mottled brown plumage. In flight, the very short tail and rather pointed wings swept upwards in a deep "V" are distinctive. Similar spp. Immature Brahminy Kite Haliastur indus has similar plumage but is smaller and has different flight action. Pied adult White-bellied Sea-eagle H. leucogaster are obvious but immatures differ only in having darker breast than belly, and brown tail (blacker in H. sanfordi) soon developing white base. Voice Series of honking cackles. Hints Common around forested islets in the Roviana and Morovo lagoons.
