SULE SKERRY AND ITS BIRD-VISITORS 301 



ToTANUS CALiDRis, Redshank. — A visitor during 

 many months of the year, but most frequent before and 

 after the nesting season ; that is in April, August, and 

 September. On 23rd July 1901, thirty appeared, the 

 largest number recorded. I saw several on 22 nd 

 September 1904. 



ToTANUS NEBULARius, Greenskunk. — Has occurred 

 occasionally in both spring and autumn. I have 

 received specimens which were killed at the lantern on

 comings and goings, for they are recorded as making 

 their first appearance from ist to 8th August, and as

 schedules, but these, no doubt, occur. 



NuMENius PH/Eopus, Whimbrel. — A few are observed 

 on the spring and autumn passages. These occur at 

 the former season from 26th April to 9th May, when 

 parties of two or three and small flocks are observed 

 on their way northwards. The return autumn move- 

 ments are recorded as from 26th July to i ith September. 

 Mr Tomison mentions that about a dozen non-breeding 

 birds spend the summer on the island. 



Sterna cantiaca, Sandwich Tern. — One which

 Arctic Terns. 



Sterna macrura, Arctic Tern. — Nests in great
