Is there a sea Europe in Tianjin Dongjiang Bay at the end of August?

Are there seagulls in Tianjin Dongjiang Bay at the end of August? No, when you watch seagulls, you must watch them at high tide. At this time, the number of seagulls is the largest, and they are close to the shore and can be fed at close range. Every year in March and April, seagulls will fly to Siberia, Australia and other regions one after another, so they can only be seen before March and April, but not at the end of August.
