Vale Pijlstormvogels Puffinus mauretanicus langs de Hollandse kust in februari 2009

On 10 and 14 February 2009 a Balearic Shearwater was observed along the Dutch coast (Noordwijk ZH and Camperduin NH). These observations followed a very good second part of 2008 with 53 observations along the coast of The Netherlands. In this note some details are presented about the status of this species as a breeding bird in the Balearic Islands and the shift in northern direction of the post breeding area along the coasts of western Europe.
