The brahminy kite, also known as the red-backed sea-eagle in Australia, is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors, such as eagles, buzzards, and harriers. They are found in the Indian subcontinent, Southeast Asia, and Australia. They are found mainly on the coast and in inland wetlands, where they feed on dead fish and other prey. Adults have a reddish-brown body plumage contrasting with their white head and breast which make them easy to distinguish from other birds of prey.

Haliastur is a genus of medium-sized diurnal birds of prey. It consists of two species of kites which form part of the subfamily Milvinae; some authorities place these species in the genus Milvus, despite clear differences in behaviour, voice and plumage.
