Fairly common summer migrant from winter grounds in Africa and Iberia. Breeds in open farmland and wetlands, with bulky stick nests conspicuous in trees and often on buildings. Distinctive: white overall with mostly black wings, very long pointed red bill and reddish legs. Flies with neck and legs outstretched, and strong, deep wingbeats interspersed with glides. Also soars on thermals; flocks migrate during daytime, often high overhead.
