Pallid Harrier

Circus macrourus

The pallid harrier is a species of harrier, a bird of prey in the family Accipitridae. It breeds in southern parts of eastern Europe and central Asia and Iran and winters mainly in India and southeast Asia. It is a rare but increasing vagrant to Great Britain and western Europe. In 2017 a pair of pallid harriers nested in a barley field in the Netherlands; they raised four chicks, the first recorded breeding of the species in the country. In 2019, a pair bred in Spain for the first time. Source
