Whimrel
are one of the commonest and regular waders during the spring
migration, with a peak in the first half of May. The species is rather
more infrequenct during the autumn migration.
The occurrence pattern of this species at Utsira is very
similar both in timing and numbers.
The blue line shows number of visits, the orange one the number of
visits when Whimbrel have been recorded and the green one
(numbers on right hand axis) shows the average
numbers I have recorded in any three day period.
