How do navigators judge the weather by seagulls?

How navigators judge the weather by seagulls;

1, seagulls often land around shoals, rocks or reefs, and flocks of gulls fly around and make noise, which is undoubtedly a signal that navigators mention anti-collision reefs;

At the same time, it also has the habit of flying in and out of the port. Whenever navigation is lost or foggy, observing the flying direction of seagulls can also be used as a basis for finding ports.

3. In addition, if seagulls fly close to the sea, the weather will be fine in the future;

If they wander along the coast, the weather will get worse gradually.

If seagulls leave the water, fly high, fly from the sea to the seaside in groups, or flock of seagulls gather on the beach or in the cracks of rocks, which indicates that a storm is coming.

According to seagulls, we can know the reason of the weather:

Seagulls can foresee storms because their bones are hollow and tubular, and they are filled with air without bone marrow. This is not only convenient for flying, but also like a barometer, which can predict the weather changes in time. In addition, the hollow feather tubes on seagulls' wings can feel the change of air pressure sensitively, just like a small barometer.
