I have seen these birds…

I have seen these birds completely iradicate our gravel pit at home. Removal all fish from our gravel pits and cause major damage at our northern hunt camp lakes to the fish population on the inland lakes. These birds were never around 10-20 years ago so you very easily notice the difference they have caused nowadays with the rise in population. I have seen flocks of 1000’s of these birds on Lake Ontario. I have seen these birds eat sea-gulls, salmon, and any fish up to 20”s long.
