The black baza (Aviceda leuphotes) is a small bird of prey found in the forests of Northeast India, the eastern Himalayas, China and Southeast Asia. Many populations are migratory, including those in the Indian region, which winter in the south of the Peninsula and Sri Lanka. Black bazas have short, stout legs and feet with strong talons, and a prominent crest. They are found in dense forest, often in small groups, and can often be found perched on bare branches of tall trees rising above the forest canopy.
This species is found in Southeast Asia and parts of South Asia. They are migratory in parts of their range. Migratory birds may be seen in large numbers at some locations such as Chumphon in Thailand where they account for nearly 40% of the raptors on passage. In some parts of Hong Kong, they have established themselves in recent times changing from summer visitors to residents in small numbers.
In southern India the species is regularly reported in winter mainly from the Western Ghats (breeding records have been questioned, Eastern Ghats (mainly on spring passage) and known to breed in northeastern India and Burma. Winter records of the species include stray occurrences in or near metropolitan areas such as the Guindy National Park in Chennai, near Trivandrum[ and Bangalore. More recent studies have suggested that the species may be a regular winter visitor in the eastern part of peninsular India, and not just a passage migrant. Individuals have also been noted at Point Calimere.
The birds in northeastern India begin to breed in April. Both sexes take part in nest building, incubation, brooding and feeding. The nest is a firm platform of thin sticks with a central depression and lined with grass, fiber and overlaid with green leaves. The eggs take about 26–27 days to hatch. Insects are the predominant food of the chicks.
