Black Kite

The black kite has a wingspan of about 150cm. Both the male and female take part in nest building, incubation and care of the chicks. Kites have also been seen tearing and carrying away the nests of baya weavers in an attempt to obtain eggs or chicks (Wikipedia, general species account).

The only source read for the Bhutan guide gives these details. No plumage, range, habitat or diet information was found, so none is stated, and its occurrence in Bhutan is flagged for checking.
