It is a common belief that when seagulls come inland from the coast, it is a sign of impending rain. However, there is no scientific evidence to support this claim. In fact, seagulls may come inland for a variety of reasons, including looking for food, seeking shelter from strong winds, or finding a place to roost for the night. While it is true that some birds, such as swallows and robins, may seek shelter before a storm, seagulls are not typically one of these birds.
The idea that seagulls coming inland is a sign of rain may be due to the fact that seagulls are often seen near the coast, where it is more likely to rain. Additionally, seagulls may be more active in bad weather, as they are able to find food more easily when there are fewer people and other animals around.
