SUT.E SKERRY AND ITS BIRD-VISITORS 301 



ToTANUS cALiJjRis, RedsJiauk. — 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 22nd 

 September 1904. 



ToTANUS NEBULARius, Greeuskank. — Has occurred 

 occasionally in both spring and autumn. I have 

 received specimens which were killed at the lantern on 

 loth April 1905, and on 19th September 1905. 



LlMOSA LAPPONiCA, Bar-tailed Godwit. — The only 

 known visit of this species occurred on 13th May 1902, 

 when a single bird appeared. 



NuMENius ARQUATA, Ctirlew. — A small number 

 winter on the island. These cold weather residents 

 are remarkably constant in observing the times of their 

 comings and goings, for they are recorded as making 

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

 taking their departure from 25th to 28th April. No 

 evidence of passage movements is contained in the 

 schedules, but these, no doubt, occur. 



NuMENius PH^OPUS, Whwibi^eL — 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 nth September. 

 Mr Tomison mentions that about a dozen non-breeding 

 birds spend the summer on the island. 



Sterna cantiaca. Sandwich Tern. — One which 

 visited the island on 25th June 1910 was killed by the 

 Arctic Terns. 



Sterna macrura, Arctic Tern, — Nests in o-reat
