A miserable morning with heavy drizzle and thick fog at times yielded another very elusive rarity in the form of a singing male Common Rosefinch. It was first seen in the Observatory back garden at about 0800hrs but then moved into the trapping area where it was last heard in the early afternoon. Also of note was a male Golden Oriole singing from the southern end of the trapping for a short time during the morning. Other migrants were few and far between but included 210 Swifts.
