The Sanford's sea eagle (Haliaeetus sanfordi), sometimes listed as Sanford's fish eagle or Solomon eagle, is a sea eagle endemic to the Solomon Islands. The "sea eagle" name is to be preferred, to distinguish the species of Haliaeetus from the closely related Ichthyophaga true fish eagles. The species was described in 1935 by Ernst Mayr who noticed that earlier observers had overlooked it, thinking it was a juvenile of the white-bellied sea eagle.
The Sanford's sea eagle was discovered by and named after Dr Leonard C. Sanford, a trustee for the American Museum of Natural History. The first description was by Ernst Mayr in 1935. It can reach a length between 70–90 cm (28–35 in) and a weight between 1.1–2.7 kg (2.4–6.0 lb). The wingspan is between 165–185 cm (5.41–6.07 ft). It is the only large predator on the Solomon Islands. The eagles inhabits coastal forests and lakes up to an altitude of about 1500 m asl.
The plumage is whitish brown to bright brown on the head and the neck. The underparts are brown to reddish brown and dark brown. The upperparts are darkish brown to gray-black. The eyes are bright brown. Uniquely among sea eagles, this species has an entirely dark tail throughout its life.
The breeding season is from August to October. The nest consists of two eggs.
The diet consists of mainly of tideline carrion, fish, molluscs, crabs, tortoises, and sea snakes, and more rarely birds and megabats snatched from the rainforest canopy. It has also been reported to feed opportunistically on the northern common cuscus.
