Wigeon tend to occurr in small numbers at Skogsøy, being
slightly more regualr and numerous in the autumn than in the spring. In
spring they start passing in early April and continue into May; in
autumn they head south between early September and early November. This
species is often seen under less than ideal migration conditions.
The blue line shows number of visits, the orange one the number of
visits when Wigeon have been recorded and the green one shows the
numbers I have recorded in any three day period.
