I had another Dormouse survey near to Dorchester today and so opted to head to Portland for a couple of hours before hand. Compared to my last visit on the 15th it was dead with very few migrants present. I walked from the main car park up the West Cliffs, through the Top Fields and down to Culverwell and then spent sometime at the Observatory Quarry. The Wryneck was still in the observatory quarry but otherwise there was very little, I recorded not a single Chiffchaff and overhead passage was non-existent. My eBird checklist for the morning can be viewed here.
