eBirders--do not include the Mute Swans on your checklist.  They are not free flying, escapees, or any other category that is proper for inclusion on a checklist; they are captive pet swans.

Random things of interest show up here on occasion.  A Sandhill Crane roosted on the frozen lake with Canada Geese one winter.  River Otters have found this campus pond in the past.
