At CBWR this afternoon a Bittern flew across the lagoon, where there were 40+ Great Crested Grebes. many in display mode, and a pair of Goosanders. Both Little Gulls amongst the thousands of mainly Black-headeds out in the Bay, and 5 Sand Martins explored the dockside holes near the former Dr Who Experience building.

East Aberthaw Lagoon

A cuckoo called from the copse at the base of the ashtip near the SW corner of the lagoon at c.11.30 this morning. Four full-grown hairy Garden Tiger larvae were putting themselves in danger by wandering over the track in search of pupating sites.

Four pairs of Tufties on the lagoon, and two broods of Mallard. Lesser Whitethroat and Reed Bunting singing and showing well there in contrast to the shy Sedge and Reed Warblers.
