You may have noticed — Kansas City is home to a large (and growing) population of Canada geese. You may have also noticed that they never seem to leave, and that is probably because most of them don't.
Many have lost the evolutionary instinct to migrate. And why should they migrate? Kansas City has it all: open lakes and fountains, green grass that is rarely covered in thick snow, few predators.
For geese, Kansas City is Beverly Hills.
