16th August

Despite the first substantial rainfall in several months and heavily overcast skies for the best part of the day it seems that all vectors of passerine migration remain headed well away from Portland and it was left to waders and gulls to give some degree of respectability to the day's proceedings, with huge increases in Ringed Plover and Black-headed Gull of particular note. Overnight moth-trapping was also crushingly duff in conditions that had looked perfect for both immigration and trapping.
