On June 23, Sparrow made his home under the bridge deck of the Qingdao Cross-Sea Bridge Viaduct. The elevated road of the cross-sea bridge along the Licun River is 20 or 30 meters above the ground, and the hollow box girder under the pavement attracts a large number of sparrows to settle down and have children, and this free "high-rise residence" can both shield the wind and rain and stay away from natural enemies. The river has a large number of aquatic vegetation and abundant food sources, making it a paradise for sparrows.
The wooden boardwalk under the bridge became a stop for sparrows
