Elanus caeruleus
Habitat
Mainly plains; seen at 3,650m in Sikkim, 2,670m in the Nilgiris and 2,020m in Nagaland
Clutch size
3–4 pale creamy eggs spotted deep red
The black-winged kite is found mainly on the plains, but has been seen at higher altitudes in Sikkim (3,650m), the Nilgiris (2,670m) and Nagaland (2,020m). The nest is a loose platform of twigs in which three or four pale creamy eggs spotted with deep red are laid (Wikipedia, general species account).
The sources read for the Bhutan guide give these altitude records and nest details only. No plumage, size, range or diet information was found, so none is stated, and its occurrence in Bhutan is flagged for checking.
