510 Mr. C. Collier on the Birds 



fifth year the nest was in the open, only two feet away from 

 the same hole. The parents were so used to our passing 

 that they became very tame, the sitting bird taking absolutely 

 no notice when we peered into the hole to look at her on her 

 nest. About the same number of pairs bred annually, with 

 the exception of 1899, when there was only about one-third 

 of the usual quantity. 



Redshank. Totanus calidrig. 



Distributed along the whole coast ; but, so far as I have 

 noticed, only one pair breeds here. 



&EENSHA2TK. Totanus canescens. 

 Rare. Occasionally seen in the autumn. 



Whimb&el. Numenius phaqpus. 



A few are occasionally noticed from the beginning to the 

 end of May. In 1901 several were seen at the end of May 

 and during the first week of June. 



Curlew. Numenius arquata. 



Breeds on the lower ground, both on the south and the 



west of the island. 



Arctic Tern. Sterna macrura. 



Very common, several small colonies nesting on rocky 

 islets. About the same number breed every year, notwith- 

 standing the fact that their eggs are taken regularly by the 

 crofters. This species is much more plentiful than the 

 Common Tern. 



Common Terx. Sterna fluviatilis. 



A small colony of from six to eight pairs breed on an 

 isolated rock ; these, with an occasional pair nesting in 

 company with the Arctic Terns, are the only instances that 

 I have observed. 



Kittiwake. Rissa tridactyla. 



About six nests yearly, in a cliff on the east of the island. 



Herrixg-Gull. Lotus argentatus. 



Some hundreds breed on the west coast, where a few pairs 

 of Lesser Black-backed Gulls nest with them.
