I have watched these bird on…

I have watched these bird on the south end of Balsam lake over the last decade destroy the trees on one island and make it uninhabitable The last 2 years I have noticed them in the North bay gobling up fish in front of our place so they are expanding their territory.
This past Aug I was shocked to see a flock of about 50 to 60 birds land in our bay and was glad to see them move on.
I hope they never get as plentiful as geese or some properties will be worth alot less along the water fronts in Kawartha Lakes.

I would have no problem on a cull to more reasonable levels for all the reasons people list. (Fish hunry bird, defoliage the trees, the poop is a slimy white and hard to clean up).
