In 1999 Cataraqui Conservation and the Friends of MJWA became partners in the Ontario Trumpeter Swan Reintroduction program, initially providing a naturalized enclosure for a breeding pair of swans. The following year the program released 12 ‘wild’ swans into the area. All of these swans were bred at the Program's Aurora based facility. Both the resident pair and the 12 wild swans bred successfully, flourishing throughout the local area and beyond. The 'benchmark' of the reintroduction program was to reach a self sustaining Trumpeter swan population, with emphasis placed on breeding pairs. The program reached that goal several years ago and MJWA played a small yet significant role in attaining success in Eastern Ontario.
While the original Trumpeter swan breeding enclosure is no longer maintained, the Friends still support a feeding program for swans and other birds, including supplemental feed throughout the winter and early spring. It is not uncommon to see 20 to 30 Trumpeter swans at the MJWA during this time of year. Currently there are two nesting pairs at the MJWA in the spring and summer.
