LONDONMost birds are acutely sensitive to changes in temperature. Scientists now say that changes in climate and warmer temperatures in parts of Europe have resulted in the migration patterns of certain birds being radically altered.
A study looking at the migration patterns of three species of duck the goldeneye, goosander and tufted duck has found there has been a sharp decrease in the number of birds migrating south.
The study, published in Global Change Biology, examined the migration patterns of the three duck species over the 1980 to 2010 period. It found that mid-winter numbers of individual ducks at the southern edge of the species normal distribution range in France, Ireland and Switzerland had dropped by nearly 120,000.
Meanwhile mid-winter numbers of the species in Finland and Sweden in areas where the ducks breed in summer had increased by a similar amount. ..................(more)
