Purple Sandpipers

I will be staying in the Thurso area for at least three days in the week commencing Sunday 3rd May 2015. Any chance of Purple Sandpipers still being In the area ? If so, help with likeliest localities appreciated. Help with any other sites for anything interesting also much appreciated.
Very many thanks,
Dave.
