130 BRITISH BIRDS. [vol. xin. 



down still present on their heads and being fed by their 

 parents. 



Up to September loth, allowing for the increase due to the 

 young broods, the numbers on the island were the same as in 

 June. 



On the nth a very distinct increase was noticed, and there 

 were quite a few in the potato fields, in the early morning, 

 having evidently arrived during the night with Meadow- 

 Pipits, Linnets and Common Buntings. By the next day 

 the numbers had again dropped to the normal, and no further 

 fluctuation was noticed. 



The Wren {Troglodytes t. troglodytes). 



A single record from the lighthouse, viz. : one bird on 

 April 30th/May ist, 1913. 



As a summer resident evidently very variable and not 

 constant, as it was not seen by Mr. Aplin or by Mr. Coward, 

 though the former expresses the opinion that it must have 

 been there. 



In June 1913 it was fairly common and with much the 

 same distribution as the Hedge-Sparrow, though not so 

 numerous and not going higher up the hill than the enclosures. 

 Verv few were found in the cultivated area at any distance 

 from the farms themselves. 



In September the summer residents and their young were 

 still present, and no fluctuation in numbers was noticed. 



The Swallow {Hirundo r. rustica). 



One spring and one autumn record from the light, viz. : 

 May 5th;6th, 1911, and September 25th 26th, 1913. Without 

 doubt a regular double-passage migrant, but chiefly diurnal. 



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

 many," and also by Mr. Coward, and as it was present also in 

 June 1913 it probably breeds regularly. In the latter year 

 the breeding population was about five or six pairs, and these 

 were seen round the farm buildings where they nest, or hawking 

 along the coast, particularly over the dry sandy shore of the 

 west bay, which was evidently a favourite feeding ground. 

 On June 15th, a blazing hot day, \vith a faint S.E. breeze. 

 Swallows were passing south down both shores of the southern 

 half of the island in ones, threes, and fives, about twenty in 

 all being seen. They did not seem to be feeding, and were 

 flying in a steady, purposeful way as though migrating. 



The local residents had apparently left the island before 

 September 3rd, as on this day only a few birds were seen and
