Whether a swan will pair with another is totally dependent upon age (the younger the better), gender (males may or may not pair but females will usually pair), and species of swan. If a swan has lost a mate, the male may or may not re-pair but usually, a female swan will re-pair. Whooper Swans have a 6% divorce rate, so they may or may not re-pair and Tundra Swans may never re-pair.

If the swans are older and are content to be left alone, we would suggest that they be left alone. If you are going to try and pair a younger pair of swans, you will need to place one in a pen (1/2 on land, 1/2 in water with feeder inside and enclosed top to bottom so predators cannot access the swan). The new swan needs to stay in the pen for approximately 2 weeks to get used to their swan taker (whomever takes care of the feeder), the new habitat and the new swan. If both swans are new to the habitat, then they both need to be placed in a pen (side by side with the same above requirements). If there is any signs of aggression, it usually means that this pairing is not going to work.

In any case, you cannot just introduce a new swan to a lake or habitat without a pen to let each of the swans acclimate to each other and the habitat. We hope this information is of benefit. The Regal Swan
