Swan are rarely observed on passage at Skogsøy, although
small flocks are occasioanlly noted on spring migration. Most records
come from cold snaps in the winter months when the birds are forced off
their usual freshwater haunts and use the shallow waters to the south
and west of the lookout point for foraging.
The blue line shows number of visits, the orange one the number of
visits when Whoopers have been recorded and the green one shows the
numbers I have recorded in any three day period.
