European
Shag has to be one the most regular species occurring at
Skogsøy, however, there seems to be a lot going on and some
very interesting information should be collected during the season of
2006. There appear to be quite defined seasonal movements of this
species - something that is often masked by movements to and from roost
sites. Not traditionally viewed as a migrant this species definitely
migrates.....
The blue line shows number of visits, the orange one the number of
visits when Shag have been recorded and the green one shows the maximum
numbers I have recorded in any three day period.
