These seagulls were spotted from the ferry between Circular Quay and Watsons Bay, Sydney. There are fish 'n' chips shops at Watsons Bay beach and the seagulls there are ruthless. Twice I've seen them swoop down and steal fish out of someone's hand. My recommendation is, wear a hat with a big brim. But then they'd probably land on it :) Anyway, these ones were comparatively peaceful; bobbing about, probably discussing tactics for the swoop.
