More than a dozen seagulls on the ice surface of the park lake are lazy together, in the winter of these two years, there are often seagulls spending the winter here, there are two bridges on the Haihe River, the water is not frozen in winter, and a large number of seagulls are gathered, and every day there will be a large amount of food thrown by the citizens to feed them, and the scene is spectacular. Birds should spend the winter in the south thousands of kilometers away, if they change to the north for winter, so that the round trip is less than a few thousand kilometers, in the long run, the birds will not degenerate.
