This winter, the area around Huangbizhuang Reservoir in Shijiazhuang, Hebei Province, has welcomed large flocks of seagulls for overwintering. The expansive water surface, mudflats, and surrounding vegetation provide an ideal habitat and resting place for the migratory birds. Improved water quality and ample water levels have nurtured abundant populations of fish and shrimp, offering a plentiful food source for the birds. The presence of these migratory birds not only testifies to the ecological transformation of the area but also paints a unique picture of vitality in the winter reservoir landscape.
