ORKNEY ROOKERY SURVEY 2010

During early April 2010, RJS counted the nests in Rookeries in Stromness and mentioned the figures to ERM asking what changes there had been over time.  Referring to the literature, ERM was reminded that there had been nothing since 1996. Plans were made to attempt to visit all the previously known Rookeries in the islands.  RJS carried out the majority of the visits but valuable contributions were also received from Alastair Forsyth, Barry & Rebecca O’Dowd, Malcolm Russell and Lee Shields.

The results are shown in Table 1 with comparable counts from the four previous surveys.  The overall total of 1,631 nests is a 14% decline on the 1996 peak count of 1,898.  This follows a period of continuous increase between 1975 and 1996.  The loss of 267 nests between 1996 and 2010 is mainly accounted for by the situation in the Kirkwall-Berstane area where 223 nests were lost and at Woodwick, Evie where a 90 nests decline was recorded.
