SUPPLEMENTARY NOTES ON THE BIRDS OF 

 ANGLESEA. 



By T. A. Coward. 



In the spring of 1905 I spent from April 12th to June 13th 

 in Anglesea, for the greater part of that time making Rhos Neigr 

 my headquarters. The village of Rhos Neigr is situated at the 

 southern end of Cymmeran Bay, at the mouth of the Crugyll, a 

 small stream which flows through marshy ground — saltings as 

 it nears the coast — and separates the sand-hills upon which the 

 village is built from the more extensive sand dunes and common 

 which border the western coast to the strait which divides 

 Anglesea from Holy Island. The sandy shores of Cymmeran 

 Bay and of the coast to the south and south-east of Rhos Neigr 

 are broken here and there by rocky outcrops, mostly covered at 

 high tide and consequently rich in seaweeds, but in places above 

 high-water mark, tidal stacks and islets, which are richly clothed 

 in spring with sheets of S cilia verna, thrift, and sea campion. 

 Llyn Maelog, a sheet of water five-eighths of a mile in length, 

 lies close to the village ; at its western corner there is a dense 

 bed of reeds and bog-bean. In these reeds many of the migrants 

 roost when they first arrive. 



A few of the summer migrants had reached Anglesea in 

 March — Wheatears and Chiffchaffs, for instance; a few Swallows 

 had been seen, and no doubt some Sand Martins and other birds 

 may have passed prior to April 12th. Fresh arrivals, however, 

 of these birds, with the exception of Chiffchaffs, were noticeable 

 in a locality which can support only a limited number of breeding 

 birds, and I was able to watch for the advent of the species 

 which usually reach us later in the season. There was, so far 

 as I noticed, only one considerable " rush " of migrants (on 

 the night of May 1st), but there were many fluctuations in the 

 numbers of the incoming or moving birds. 



In the early days of April the wind was chiefly in the west ; 

 we had very cold weather from the 6th to the 9th ; about this
