The White-bellied sea eagle is a large raptor with a huge wingspan. From head to tail it measures about 2m and with its wings folded, length is 1.5-2m (4ft 10in – 6ft 7in).
It has brown and white mottled feathers and a grey face which makes them easy to spot among other sea eagles. Its eyes are dark brown, legs and feet are yellow and beak is black.
Males and females look alike but only the adults have white bellies; juveniles have brown bellies until 5 years of age when they become white underneath as well.
Their distinctive loud call is similar to that of a Hog Deer or Indian Peafowl.
