What time of year do cygnets hatch?

Cygnets, or young swans, typically hatch in late spring to early summer, around May to June, depending on the species and geographic location. The exact timing can vary based on environmental conditions and the specific breeding habits of the swan species. Swans usually build their nests in wetlands, and the incubation period lasts about 35 to 40 days after the female lays her eggs.
