Caspian terns

Caption

Male Caspian terns are not only responsible for leading their young on their first autumn migration to wintering quarters, but they also have an important role in defending their young against possible threats. Here a young tern (bottom right corner) roosting on a stopover site together with its parent which is seemingly not happy with a young common gull approaching.
