The pied harrier (Circus melanoleucos) is an Asian species of bird of prey in the family Accipitridae. It is migratory, breeding from the Amur valley in eastern Russia and north-eastern China to North Korea. Wintering individuals can be found in a wide area from Pakistan to Philippines. The population consists of approximately 10,000 individuals and the number is thought to be in moderate decline. This medium-sized harrier (length 45 cm and wing span 115 cm) nests in steppes and associated wetlands. Wintering individuals are often seen hunting above rice paddies and marshes.
