Originally native to Ontario, the Trumpeter swan’s extirpation from eastern Canada over 200 years ago was primarily due to hunting pressure and habitat loss.
Biologist Harry Lumsden began a provincial reintroduction program in the early 1980’s to re-establish the Trumpeter swan in its former habitat and range.
These swans are well monitored and almost every one has a yellow identification number:
I have led walks on the Orchard (and other) Trails at Rouge Park many times. It has an ideal variety of stream, pond, forest, cliff and field.
But now they drift on the still water,
Among what rushes will they build,
By what lake’s edge or pool
Delight men’s eyes when I awake some day
To find they have flown away? – William Butler Yeats
