I spent the morning working but managed to see my first Sandwich Tern of the year off Norwick and presumably the same individual during a subsequent quick look at Skaw where I was surprised to re-find the Short-toed Lark. On an evening return with Brenda whilst we failed to see the Short-toed Lark we had a Shore Lark fly west.
Skaw: Whimbrel, 2 Common Sandpiper, Sandwich Tern, 20 Swallows, 6 House Martin, 8 Sand Martin, Short-toed Lark, Shore Lark, 2 Blackcap, Chiffchaff, 2 Willow Warbler, 4 Mealy Redpoll
