Motacilla flava
Passage migrant, has bred.
The Yellow Wagtail has a breeding range spread throughout most of the temperate regions of Europe and Asia, extending into Alaska. The western European population winters in Africa. There are at least 15 subspecies, most of which are recognisable in the field. The subspecies which breeds in Britain is M. f. flavissima.
The following account refers to M.f. flavissima unless stated otherwise.
From the time of the first Pembrokeshire avifauna, written in 1894, to the present day, the Yellow Wagtail has principally been a passage migrant recorded in both spring and autumn. The exceptions were when a pair bred successfully at Lower Broadmoor, Talbenny, in 1997 and a pair behaved as if nesting in a potato field at Treginnis in 1983, which disappeared when the crop was harvested. In both cases the male was of the Blue – headed form M.f.flava.
The first record traced of Yellow Wagtails in Pembrokeshire which gave the number involved, the location and the date, was of five at Cilwendeg on the 24th August 1867 noted by Thomas Dix. It was 1930 before the next such record was forthcoming, followed by records in 1931, 1948 and 1949, in four years in the 1950’s, in eight years in the 1960’s, four years in the 1970’s and in every year from 1981 to 2008.
