VERKADE H (2013) Winter concentrations of Woodcock Scolopax rusticola along the coast of Zuid-Holland in 2009-2013. LIMOSA 86 (4): 222-228.
During five recent winters (2008-2013), remarkable concentrations
of Woodcock were observed in the coastal village of
Noordwijk, Zuid-Holland. These five cold winters followed
after a decade of mild winters. Woodcocks were counted
weekly along a fixed route in a rather open area between
the coastal and inland parts of the village. At the end of cold
spells with snow and ice, up to 200 Woodcocks were counted
during daytime, and during the night more than 60 foraging
birds were observed in the same area. The question is raised
whether these concentrations are extraordinary winter influxes
of birds originating from Northeastern Europe, or a
sign of a more regular wintering in Dutch coastal regions due
to the moderate climate along the North Sea. Historical reports
of Woodcocks wintering in the Netherlands are rather
scarce. Until the late 20th century they were reported only in
rather small numbers and no winter-influxes were described.
Since then, more substantial winter numbers have been reported
in the coastal province of Zeeland and highest concentrations
were observed along the Dutch coast. It seems
that Woodcocks have extended their wintering grounds towards
the North(east), and that the cold winters of 2008-2013
forced the birds to move in large numbers towards milder
areas along the coast.
