These geese were actually put here by state agencies in the 1960s, '70s, and '80s as part of public programs to create Canada goose populations after nearly hunting the bird to extinction. Because these birds are all protected by the Migratory Bird Treaty Act, it proves surprisingly difficult to get the geese to leave.There are some methods of geese removal, like egg oiling, or addling, that stop new geese from hatching. It’s a lot of effort, but it works. Still, these Canada geese illustrate some of the unintended consequences that happened when people tried to foster flocks in the last half-century.Further Reading:Home grown honkers was a definitive guide to goose raising.
