few Greylags are seen on spring migration past Skogsøy, with
small numbers noted from late March onwards into the second half of
April. The species is much better represented during the autumn
migration which commences in late July and peaks in early August (this
is likely to be the Norwegian population). Smaller numbers are recorded
as the autumn progresses.
As for many species of wildfowl the numbers seen at Skogsøy
are a lot higher than at Utsira.
The blue line shows number of visits, the orange one the number of
visits when Greylags have been recorded and the green one shows the
numbers I have recorded in any three day period.
