16 The Birds of Pembrokeshire. 
Dix in considering this beautiful species, ‘ the Common Wag- 
tail” of Pembrokeshire, breeding by every little stream. We 
have found the nest within a few feet of our hall door at Stone 
Hall. 
BLUE-HEADED YELLOW WAGTAIL, J/aclla flava.—A rare 
summer visitor from the south. Writing to us from Dale on 18th 
October, 1886, Mr. H. Mathias informs us: ‘‘I am now able to 
say for certain that the Greyheaded Wagtail is to be found in 
Pembrokeshire. My friend, the Rev. Lyte Stradling, an orni-

the small bridge, dividing the parishes of Marloes and Dale, on 
more than one occasion, and yesterday afternoon there was 
one running about the road in front of my abode at this place. 
I had a good opportunity of watching it, for it was not five

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. 
MEADOW PIPIT, Axthus pratensis—A common resident. Mr. 
Dix says: ‘‘ Breeds on the mountains and bogs. I have seen 
this bird on the tops of the mountains, where, excepting the
