Double-crested Cormorants – North America’s most persecuted waterbird
After being nearly wiped out by human persecution and pesticide poisoning, the Double-crested cormorant has returned to the Great Lakes. Cormorants are a native Ontario water bird who have not yet recovered to historic population levels.
The return of cormorants is a good news environmental story that indicates reduced pesticide levels. As well, cormorants are the only major predator of several damaging invasive fish species. Sadly, special interest angling groups – who erroneously claim cormorants are responsible for depleting sport fish numbers, destroying shoreline ecosystems, disturbing other colonial water birds and causing pollution – are pushing for their eradication.
Cormorant Defenders International is working to rehabilitate the image of Double-crested cormorants, to stop abusive, unnecessary “population management” practices and to prevent the indiscriminate slaughter of cormorants throughout Ontario and parts of the United States.
