Details

The Crested Grebe is a summer bird that lives from the northeast to the Qinghai-Tibet Plateau and winters in most areas south of the Yangtze River. During the breeding season, it has complex courtship behaviors, with male and female individuals performing a ritualized "dance" on the water surface: the two individuals cooperate with each other, remain perpendicular to the water surface, nod to each other, and sometimes hold water plants in their mouths.

The Crested Grebe has strong diving ability and feeds on mollusks, fish, crustaceans and aquatic plants. The breeding season is from May to July. It builds nests in reeds or cattails with good concealment conditions, using reeds and water plants as nest materials. Each nest lays 4 to 5 eggs, which are oblong and grayish white.

During the breeding season, pairs perform exquisite courtship displays, looking at each other, holding their bodies high and nodding at the same time, sometimes holding plants in their mouths.

It is a winter migratory bird. It inhabits coastal areas, lakes, reservoirs, rivers and other waters. Its food is fish, shrimp, aquatic insects, and some aquatic plants.

It often moves in pairs or small groups. It is good at swimming and diving, but not good at flying. Its nests are mostly located among water plants in shallow water.

The adult bird makes a deep and loud call. The chicks make a ping-ping sound when begging for food.
