Circus assimilis

Partly migratory in S, some birds wintering in tropics; status uncertain in Sula Is and Lesser Sundas, but probably only migrant to latter. In S, departure and locality of subsequent return determined by local rainfall: birds leave in dry conditions, return to areas with good rains and plagues of prey.
