Cormorants are a commonly known species in Ontario.
Many people can quickly identify a Cormorant in many areas of Ontario, in fact this summer alone I have viewed more Cormorants than I ever have in Northern Ontario. When I sight these birds they are commonly in larger groups alone shorelines or small islands. It's easy to observe the areas they inhibit for long periods of time as they are covered in Cormorant faces leaving a white-grey stain on impermiable surfaces, and moss-wear on rock islands.
Though I have not personally witnessed an area of shoreline where groups of Cormorants intermingle, I have read erosion is a large worry and the contents and contents within the feces, as it commonly is detrimental to grass/dirt/tree trunks.
Noting the habitat quality where these Cormorants have been personally sighted, I find it easy to believe the destruction to landscape these birds are capable of.
I think opening a hunt of the Double-creasted Cormorant in Ontario is a good idea, and if not permanent, an experiment worth the time. If monitoring stats note a large decline after the 2019 season, reversing the hunt is always an option.
