VOL. XIII.] THE BIRDS OF BARDSEY ISLAND. 189 



The Little Stint {Erolia m. minuta). 



A single bird was taken at the lantern on October ist/2nd, 

 1913- 

 The Dunlin {Erolia a. alpina). 



A regular double passage migrant. 



Spring passage, from mid-March to the third week in May. 



Autumn passage, from early August to early December, 

 once on July loth'iith. 



On May 23rd and 24th, 1901, Mr. Aplin saw one or two in 

 the east bay ; but neither Mr. Coward nor I saw any in June. 



In September 1913 three were seen on the 3rd and two 

 each day from the 4th to the 8th. There were four or five 

 on the 9th, and a single bird on the 13th was the only other 

 one seen. 



The Purple Sandpiper {Erolia m. maritima). 



A single Purple Sandpiper was seen on the coastal rocks 

 on September 3rd, 1913. 



The Common Sandpiper {Tringa hypoleuca). 



Once recorded from the light, a few on August 6th/7th, 



1913- 



One was seen by Mr. Aplin, and he suggests that it may 

 breed ; there are certainly one or more suitable places ; but 

 Mr. Coward saw nothing of the species, and there were none 

 on the island in June 1913. 



In September 1913 two were seen on the coastal rocks on 

 the 3rd ; two others on the 7th, and two others on the i6th. 



It is quite probably a double -passage migrant, but the 

 records are too few at present to say anything for certain. 



The Common Redshank {Tringa totamis). 



Once recorded from the light in spring, March 7th/8th, 

 1913, and twice in autumn, August 28th/29th and 30th/3ist, 

 1913, and once in winter, December 12th 13th, 1909, on the 

 last occasion in considerable numbers. 



As a summer resident at present doubtful, though there are 

 one or more suitable places for nesting. None were seen by 

 Mr. Aplin, but Mr. Coward saw one (or more ?). In June 1913 

 I found two pairs on the coastal rocks of the southern half of 

 the island on the 15th, and each time I visited this part of the 

 island I saw some. On the 17th there were three, on the 19th 

 a flock of twelve, and on the 21st a flock of fifteen, old and young 

 mixed. It is clear that a gradual downward movement was in
