Shelduck are regular spring migrant in small numbers at
Skogsøy;
when migrating they regularly join flocks of other species - such as
Great Cormorant. The spring migration starts in mid March and continues
to early May. Very occasioanlly they can be seen on the sea
in
the sheltered bays - something that may indicate that breeding could be
attempted. The species is also seen during the autumn, though less
regularly and in smaller numbers.
The
occurence
pattern and numbers of Common Shelduck at
Skogsøy seems very similar to Utsira.
The
blue line
shows number of visits, the orange one the number of
visits when Shelduck have been recorded and the green one shows the
maximum
numbers I have recorded in any three day period.
