Did you know there are three species of swan in North America? The trumpeter swan and tundra swan are native, while the mute swan is originally from Europe and Asia.
Trumpeter swans are found in Ontario. These large white birds with black bills started to decline in number roughly 200 years ago due to hunting and wetland destruction.
In 1982, the Ontario Trumpeter Swan Reintroduction Program was established to return the species to its previous numbers. In 1989, a pair of captive birds was placed at Wye Marsh Wildlife Centre in Midland. The following year they gave birth to two young swans (cygnets). Ontario now has a self-sustaining population of over 1,000 birds.
Some of these birds are marked with a numbered yellow wing tag. These numbers allow for population tracking that can show which birds survive, where they reside and if they are bearing young.
CVC staff document the location and tag number of trumpeter swans in the Credit River watershed. Our findings are then sent to the Trumpeter Swan Reintroduction Program and they send us back information on a bird’s age, gender and where the bird was originally tagged. The information gathered on trumpeter swans helps us determine the success of the Trumpeter Swan Reintroduction Program and document wildlife in the Credit River watershed..
