THE FLANNAN ISLES 273 



The autumn movements range from 2nd October to 

 19th November, when the bird sometimes appears in 

 thousands. 



On 5th December 1902, numbers appeared with 

 Fieldfares ; many of them were found afterwards too 

 weak to fly. 



Fieldfare, Turdus pilaris. — A bird of double 

 passage, and a visitor during stressful periods in winter. 



In spring, has been observed from 15th April to the 

 end of the first week of May, and occasionally as late as 

 6th June. 



The earliest record for its appearance in autumn is 

 3rd October, and it occurs in numbers from the middle 

 of that month down to 19th November. 



Blackbird, Turdus merula. — Regular and numerous 

 on both passages, and a visitor during cold spells in 

 winter. 



In spring it has been observed from the earliest days 

 of March to 12th May; and in autumn from 29th 

 September to 20th November, often in considerable 

 numbers. 



RiNG-OuzEL, Turdus torquatus. — This species has 

 visited the island in a few instances only. In the spring 

 of 1908 single birds were observed on 28th and 29th 

 April; and in 1910 one appeared on 14th May. On 

 2nd October 1907, several appeared, and on the two 

 following days single birds were seen.
