Red-breasted
Merganser are one of the most regularly seen species at Skogsøy
throughout the year but are less regualr from July to September. The
diagram below includes stationary birds so some of the passage is
masked. However, there is a definte spring passage and an even more
marked autumn migration with a peak in the first half of November.
Once again, this is a species that is seen more at Skogsøy than at Utsira.
The blue line shows number of visits, the orange one the number of
visits when Red-breasted Merganser have been recorded and the green one (numbers on right hand axis) shows the
average
numbers I have recorded in any three day period.
