Motacilla raii
A passing visitor in spring and autumn; rare in Pembrokeshire, and occurring only in the southern parts of the county; we have never ourselves seen it. Mr. Dix writes: " I have only once been able to identify this bird in this district, when five were seen on 24th August, 1867. Mr. Tracy, of Pembroke, says : " Tolerably common in small flocks, at the latter end of August and September, frequenting pasture fields where cattle are grazing. I have oftentimes wondered how they avoided being trodden on by the cattle. Good old specimens are very scarce." It is very doubtful if this species nests within the confines of the county.
