Skua are a bird of the spring at Skogsøy, with relatively
the summer and autumn. The first birds turn up towards the end of April
and there is a clear peak in the first half of May. Huge numbers have
been recorded during onshore winds during May but this seems to be a
relatively rare event.
It would seem that this species is noted in larger numbers at
Skogsøy than at Utsira, especially during the spring.
For further details see Pomarine Skua
The blue line shows number of visits, the orange one the number of
visits when Arctic Skua have been recorded and the green one
(numbers on right hand axis) shows the average
numbers I have recorded in any three day period.
The following books are highly recommended - not surprisingly I have
both of them...
