Why do seagulls gather high in the air and fly in circles?
Gulls like to float on the air currents so that they can excert as little energy as possible. They will find an updraft, and stay with it. Seagull vision is very keen and they can see fish below the water even at high altitudes. Sometimes they circle at high altitudes while they wait for a school of fish to come close to surface where they are easy to catch.
