Actitis hypoleucos – PIBYDD Y DORLAN – Passage migrant and winter visitor, formerly bred
Mathew (1894) stated that Common Sandpipers bred near Maenclochog. Lockley et al. (1949) chose not to admit this record and there have been no breeding records in Pembrokeshire since.
Autumn passage commences as early as 19 June and continues to mid-October, with a late group of 11 on the Cleddau Estuary on 11 November 1984. Small parties of up to 13 occur on all estuaries, on coastal pools, rocky shores, offshore islands and inland ponds and streams.
Up to four winter on the Cleddau Estuary each year, most consistently at Westfield Pill. One wintered on the Nevem Estuary in 1968 and one was seen at St Bride’s Haven on 26 January 1987.
Spring passage is smaller than that of the autumn, with groups of up to five stopping off briefly between 5 April and 24 May and seen in similar areas.
They have been heard passing over the county at night and have been seen during lighthouse attractions at the Smalls and South Bishop.
