Kingfishers in the Netherlands are doing exceptionally well due to the recent mild winters. In the Dutch language they are called ijsvogels, which means ice birds. Despite that name, the birds do not fare well in cold winters.
Ten years ago the population of Kingfishers in the Netherlands consisted of only 150 breeding pairs. Today there are several hundred.
