Quick check of Furzton Lake today to follow up a report of a Sandwich Tern yesterday afternoon. As suspected it had already moved on. With just a single Common Tern and 6 Swifts moving through. Another stop off at CMK again produced nothing but a Small Tortoiseshell on one of the Buddleia.
Sandwich Tern and Wood Warbler are my major bogey birds for Buckinghamshire.
