Summary:
Finnish
farmers are adapting to the warming climate by anticipating the time when they
sow their fields in the spring. At the same time, birds have also advanced the
time of breeding as the spring temperatures are becoming milder in response to
climate change.
A
new study shows that birds have shifted the time of their breeding much faster
than the farmers are anticipating their sowing times in Finnish farmland. This
means that more birds are nowadays laying their eggs on fields that are still
to be sown, a mismatch in timing that is most likely fatal for the bird nests.
"As
the eggs of curlew and lapwings are placed on unsown fields, they are likely to
be run over by farming machinery during sowing operations even if farmers were
willing to avoid nest destructions," says researcher Andrea Santangeli
from Finnish Museum of Natural History, which is part of University of
Helsinki.
