Canada Geese but more commonly called Sky Rats here. Stupid things are everywhere. Green tootsie rolls on every golf course, park and lawn near water.
And the problem is that since they're technically "migratory waterfowl" they're under state and federal protection, so its difficult for property owners or local authorities to do anything about them. In more temperate climates, the only way the damn things will actually migrate is if you buy them a 1st class plane ticket to Miami.
What they do here is spray the eggs with mineral oil. If you break them, they'll lay more but if you spray them with oil, the egg will sufficate and won't hatch and they'll still sit on them without laying new ones. Personally, I think they should do a cull and donate the meat to food banks etc but most people think I'm cold-hearted. Plus, people probably wouldn't eat them. I do, taste like goose.
