Canada geese are a pia! I saw an episode of Billy the Exterminator where he took a service call by a lady that had nesting pairs on the roof of building. Billy and his bro lured the geese off the nest and took their eggs and wiped them down with oil so they wouldn't hatch. Chicago's parks have big ponds the geese took over. Vagrants and homeless have pretty much wiped them out.
