186 BRITISH BIRDS. [vol. xiii. 



so far beyond the normal range of the species. It is safer for 

 the present to regard these two individuals as vagrants. 

 In September a single bird was seen on a stubble on the 3rd. 



The Oystercatcher {Hcematopus 0. ostralegus). 



Three spring records from the light, between the end of 

 March and mid- April, and four autumn ones between the 

 first week of August and the first week of September. 



As a summer resident recorded by Mr. Aplin as " fairly 

 common, especially round the rocks of the south point and 

 along the west side," also by Mr. Coward. In June 1913 

 it was distributed all round the island, nesting on or near the 

 rocky margin. On the east coast it is impossible to compute 

 the numbers, but wherever one could get a view of the lower 

 part, a pair could generally be seen. This also applies to the 

 eastern part of the north coast ; on the western half there 

 were three pairs, with two more at the north-west comer. On 

 the west coast, north of the bay, there was only one pair. 

 Round the southern half of the island there were some nine 

 or ten pairs, possibly twelve ; and another pair on a rocky 

 stack in the east bay. 



Most pairs had young by June 12th, a brood on that day 

 being about three daj's' old. Five nests with eggs were found, 

 one of which was just hatching on the 15th. 



In September a great decrease in the summer population 

 had already taken place by the 3rd, and from then to the 9th 

 only three or four birds were seen each day. The numbers 

 rose to about a dozen on the loth, and decreased again to 

 five or six on the 17th. On the 21st there was a real migratory 

 movement : a flock of seventeen were on the rocks in the early 

 morning, besides odd scattered birds. At the south point, 

 where we sat the whole morning, we saw a flock of nine, 

 evidently performing a migratory journey. We first heard 

 their piping call in the distance, and picked them up far out 

 at sea with our glasses. They were flying at a good height, 

 perfectly straight and steadily from N.N.W. to S.S.E., which 

 line took them at a tangent past the end of the island, and we 

 watched them till out of sight a long way to the south. 



The Ringed Plover {Charadrius hiaticida). 



Once recorded from the light in spring, March 29th /30th, 

 191 1, and five times in autumn, November 5th 6th, 1909, 

 October 28th/29th, 1910, August 29th 30th, September 2nd /3rd 

 and 3rd '4th, 1913, in small numbers on each occasion. 



Probably a regular double-passage migrant.
