I’m not sure I see the downside of thinning the herd of Canada Geese.
Not only is it really really cruel (the goslings peeping endlessly in confusion for their mothers, mated pairs separated, etc.), but it is scientifically a stupid way to attempt control. If you remove the resident population of geese, considering the prime habitat they occupied, more geese will promptly colonize it. I used to take my biology classes out to Jamaica Bay Wildlife Refuge for nature walks and the favorite bird that they saw on the trip was ALWAYS the Canada geese and their goslings. How could I explain to them, since the anal orifice Gillibrand sneaked that stupid legislation into a food stamps bill, that the cute baby goslings they admired would, in a couple of months, be rounded up and gassed?
