Case in point: Boston Common. Now there's a real "green" piece of real estate. And I don't mean the grass.
A hospital in a large Missouri city, after never having geese, suddenly became a place where they stopped, and after having stopped, stayed...they were a real nuisance...I was there for weeks when my father was dying...step mom and I would go have a smoke, see all the geese...
They may be there still, for all I know. We kept geese for a few years, very territorial and aggressive birds. Beautiful, but as good as a watchdog for the noise and attempts to bite. Getting hit by a wing is not "soft"--the dang bones are hard as rocks and leave bruises...plus those bills are sawtooth edged, and they know how to use them.
They are magnificent, though, bathing in the pond, very very beautiful.
