Temperature drop

First morning under 10 degrees this morning and not a Common Tern in sight. Meadow Pipits noticeably moving and a Tree Pipit too. Yesterday a flock of House Martins moved through and there were some more this morning, though not so obviously moving. Also in were some RB Mergansers (6) and a flock of 13 Shelducks which flew over towards the harbour was interesting.
