Swan's spawning habit is to lay eggs on land near lakes, such as wetlands and hay.
Swan migrates northward from mid-March to mid-April every year, and breeds from May to June. Most nests are placed on dry ground or among reeds in shallow water, and each nest lays 4-7 eggs. The male swan and the female swan form a lifelong spouse. Courtship behavior includes touching the beak or leaning on the head. The female swan hatches eggs, and the male swan stands guard nearby; Some kinds of males also replace incubating eggs. Young chicks have short necks and dense villi; You can run and swim after a few hours out of the shell.
