Cormorant, Skogsøy, March 2012
Cormorants
are seen on the vast majority of seawatches at Skogsøy and
are
one of the commonest birds there. The spring migration picks up in late
March and continues well into May before it drops off rapidly. The
autumn migration is a much more protracted affair commencing in late
August and continuing well into November.
There are a number of interesting migration patterns I will be looking
into in 2006, such as the timing of the migration for various ages (it
seems non-breeders also head north....).
This is a species that can often pass overland or over the fjords - in
other words it is easy to miss some or most of the Cormorant passage if
you are just looking out to sea.
Numbers at Skogsøy far outweigh those at the better known
Utsira
- probably largely because this species tends to hug the coast during
its migration.
The blue line shows number of visits, the orange one the number of
visits when Cormorant have been recorded and the green one shows the
average numbers I have recorded in any three day period.
