sometimes killed in hundreds, and even when the light is not 

 very attractive, the "zip zip^' of the Thrush and the " zieh " 

 of the Redwing may be heard on many a night as they fly 

 round in the rays. 



Turdus pilaris. The Fieldfare. A bird of double pas- 

 sage and a frequent visitor in winter; the regular migration 

 begins in March, but April and May are the periods of 

 maximum movement. There are two June records — on 

 2 June 1911, and 6 June 1915, Autumn migration has 

 been noted as early as 25 September, but the main arrival 

 takes place between mid-October and mid-November. 

 Fieldfares also sometimes move by day ; on 24 October,

 many at the lantern and on the island, almost all being 

 young males with black bills.

 of double passage, from mid-April to mid-May, and again 

 throughout September and October, and even up to 

 22 November. 



Phoenicurus phcenicurus phoenicurus. The Redstart. A 

 bird of double passage, from mid-April throughout May and 

 even into June; these later birds were doubtless passage 

 migrants on their way overseas. Single birds are recorded 

 on 29 June, 1882, and 13 July, 1914, but regular movement 

 does not begin till the last week of August, and lasts till the
