If you have been in an area where swans are common you may have noticed that one of the swans seems to be missing. Where once there were two....there is now just one.Don't be alarmed. The second swan is probably not too far away. She is just otherwise engaged.
She is probably sitting on her nest. Swans build huge nests and lay anywhere from half a dozen to a dozen eggs and they will need room for all those little babies.
Baby swans, called cygnets, will hatch somewhere around mid to late April. If you know where there is a swan nest do not approach it. Swans are very protective, especially the males and can cause quite a bit of harm if they think you are intruding. Be especially careful with children. Watch and enjoy from afar!
