I have witnessed entire shoreline islands with trees and ground cover killed by the toxic effect of bird guano. The islands were inhabited by colonies of cormorants. In Georgian Bay, cormorants have been aggressively reducing small fish, on which salmon, whitefish and trout depend. This is unlike any other wildlife effect anywhere I've seen across Canada because they are aggressive and destructive. This bird has taken advantage of the abundance of freshwater lakes in Ontario.

This is an invasive species. Cormorants need to be controlled and removing them from Ontario is warranted.
