Abstract: On 31 March 1994 a Purple Heron Ardea purpurea was being observed flying on migration in a northeasterly direction off Qammiefl. On approaching the South Comino channel an adult Yellow-legged Gull Larus cachinnans started chasing and mobbing it. After a while, two other Yellow-legged Gulls joined in. Suddenly, the heron, with an outstretched neck, chased the gulls away and kept on its course. However the Yellow-legged Gulls returned and mobbed the heron again, giving up only after the Purple Heron had passed over Cirkewwa.
