Yesterday's whinchat was showing briefly south of the observatory mid morning, and a black redstart was around the fort. A great spotted woodpecker was the first we've seen in a while, and a young sparrowhawk made short work of one of our linnets. A blackcap and a sedge warbler were in the compound, along with two willow warblers, the most notable warbler species of the day. More juvenile blackbirds keep turning up, perhaps local birds that have hidden well or some fledglings from Felixstowe.
