On 18-19 January 2014, there was the mid winter bird count in the Netherlands, like in every year.
All figures are not in yet. So far, 3,2 million birds were counted.
One remarkable result is about great egrets. A few decades ago they were very rare birds in the Netherlands. However, since 1980 this species increased greatly in Europe. Now, about 2,800 great egrets winter in the Netherlands. Maybe even more this winter. In this winter bird count, great egret numbers were 60% of grey heron numbers. While grey herons used to be much more numerous. People think great egrets in western Europe benefit from better conservation and from global warming. When will great egrets surpass grey heron numbers?
