Knot are occasional spring migrants, occurring around mid May - it is
at this time the record was set. In autumn they are reasonably regular
in early August and then again between the end of August and mid
The occurrence pattern of this species during the autumn at Utsira is
similar both in timing and numbers, although the species is not
recorded there during the spring. A similar double peak in the autumn
is also seen at Stag Rocks, Northumberland (UK).
The blue line shows number of visits, the orange one the number of
visits when Red Knot have been recorded and the green one
(numbers on right hand axis) shows the average
numbers I have recorded in any three day period.
