Every 10th day during breeding seasons the colonies on these
small artificial islands of Ringkøbing Fjord, along with
several other colonies of the western Jutland, are visited
by the authorities and consequently eggs of society’s enemy
the Cormorant are destroyed.
That’s to say, destroyed, in an organized, well planned and
truly intelligent way, that only a true civilisation can
provide. And under the supervision of Denmark’s
Environmental Research.
In this well planned operation, including a carefully
outlined number of nests, eggs are sprayed with coloured oil
that seals the gas permeable pores, consequently killing the
embryo. The Cormorants return to the nest and continue their
hatching showing little or no reaction to the clear blue
colour, but later on, during a following visit to this
colony, any new white eggs in any of these nests catch the
eye, can be easily located and consequently treated with
blue oil.
Otherwise destroyed eggs or nests, would simply cause a bird
to either produce a new set of eggs or give away space to
another breading ready couple of Cormorants.
This is the way to do it.
12% of the total number of Cormorants nests were destroyed
in this way during 2005, or 5.000 in all in an operation
concentrated in Western Jutland and around the island of
Læsø.
According to Denmark’s Environmental Research this nest
destruction was carried out at 15 colonies corresponding to
27 % of all of all colonies in Denmark. |
