For info for anyone thinking of going for the Brunnich’s Guillemot in Portland Harbour, here’s a map of the best place to park – plenty of room and it’s free!
Basically go all the way across the causeway/road over towards Portland Bill and at the very last roundabout where there’s a brown sign for Portland Castle, turn left and about 200m along this road there’s a dirt car park. This gives access to the shoreline by the Castle and and also along to the sailing academy. When I saw it on boxing day it was very mobile but did give exc views near the shore, but when it dives it can travel a long way before it comes up again! There’s also a BLack Guillemot in that location and all three divers. On the other side of the harbour at Castle Cove I had all three ‘rare’ grebes [there were at least 8 Black-necked and singles of Slav and Red-necked].
For this park here, just before the entrance to Castle Cove sailing club:
