11-3-2020 KERULA, INDIA - BRAHMINY KITE EAGLE (Haliastur indus)
The brahminy kite (Haliastur indus), 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.

12-3-2020 KERALA, INDIA - BRAHMINY KITE EAGLE (Haliastur indus)
The brahminy kite is distinctive and contrastingly coloured, with chestnut plumage except for the white head and breast and black wing tips. The juveniles are browner, but can be distinguished from both the resident and migratory races of black kites in Asia by the paler appearance, shorter wings, and rounded tail. The pale patch on the underwing carpal region is of a squarish shape and separated from Buteo buzzards. The brahminy kite is about the same size as the black kite (Milvus migrans) and has a typical kite flight, with wings angled, but its tail is rounded unlike the Milvus species, red kite, and black kite, which have forked tails. The two genera are, however, very close.
The call is a mewing keeyew.
This kite is a familiar sight in the skies of Sri Lanka, Nepal, India, Iran, Pakistan, Bangladesh, and southeast Asia and as far south as New South Wales, Australia, through which region it is widespread and resident. They perform seasonal movements associated with rainfall in some parts of their range.
They are mainly seen in the plains, but can sometimes occur above 5000 feet in the Himalayas.
It is evaluated as being of least concern on the IUCN Red List of Threatened Species. However, the species is on the decline in some parts such as Java.
The breeding season in South Asia is from December to April. In southern and eastern Australia, it is August to October, and April to June in the north and west. The nests are constructed of small branches and sticks with a bowl inside and lined with leaves, and are located in various trees, often mangroves. They show considerable site fidelity nesting in the same area year after year. In some rare instances, they have been seen to nest on the ground under trees. A clutch of two dull-white or bluish-white oval eggs measuring 52 x 41 mm is laid. Both parents take part in nest building and feeding, but likely only the female incubates. The incubation period is about 26 to 27 days.
It is primarily a scavenger, feeding mainly on dead fish and crabs, especially in wetlands and marshland, but occasionally hunts live prey such as hares and bats. They may also indulge in kleptoparasitism and attempt to steal prey from other birds.Brahminy kites have even been recorded taking advantage of Irrawaddy dolphins herding fish to the surface, in the Mekong River. A rare instance of a bird feeding on honey at the hive of Apis florea has been recorded. It also eats rice or cooked food left as an offering in India.
