106 The Birds of Pembrokeshtre. 
There is no nesting place of this pretty species, that breeds on 
the ground in swampy places, and by the edges of lakes, in 
Pembrokeshire, nor in any of the adjoining counties that we can 
discover. Indeed, the only place in the Principality that we at 
present know of (we consider there must be some others) where 
the Brown-heads nest, is on Mochras Island, on the coast of 
Merionethshire, where Mr. J. H. Salter found empty nests and 
other traces that the birds had reared young, at the end of 
June. 
LITTLE GULL, Zarus minutus.—An occasional visitor ; rare. Mr. 
H. Mathias informs us that examples of this small species, that 
is no larger than a common Pigeon, have been obtained in the 
county, but can furnish no particulars, and has not included it 
in his list of birds supplied to Mason’s Guide to Tenby. We 
are indebted to Mr. C. Jefferys, of Tenby, for telling us of the 
occurrence of an adult Little Gull in winter plumage, at that 
watering place, on the south sands, at the beginning of January, 
1892. This specimen is now in the Tenby Museum, and we 
have a very pretty photograph of it, with its wings extended, that 
was kindly forwarded to us by Mr. C. Jefferys. There were two 
seen when this bird was obtained, but the other, being only 
slightly wounded, succeeded in escaping. As the Little Gull 
has been observed at Lundy, and has frequently been obtained 
on the coasts of Devon and Somerset, it is evidently no very 
great stranger in the Bristol Channel, and we consider that it 
must sometimes enter the fine harbour at Milford Haven, where, 
no doubt, some of those mentioned by Mr. Mathias were 
obtained. 
SABINE’S GULL, Xema sabinit—A rare, occasional straggler from 
the far north; only three occurrences. In Mr. Mathias’ list. 
One killed by a keeper of Lord Cawdor was seen by Mr. Mathias 
in Tracy’s shop, at Pembroke. This was a young bird in the 
first year’s plumage, and is now in the collection at Stackpole.
