A singing Serin was an unexpected surprise this morning but it soon did the old disappearing trick. Also on the move were 2 Crossbills & 5 Curlew south. Autumn passage well underway for Curlews already this year but its difficult to define what the Crossbills are up to - "eruption" is the word most often used for this species. Plenty of terns still offshore & plenty of baby birds - at least three of the four pairs of Whitethroats have churned a brood out as an example.
