428 Major W. R. Thompson on the [Ibis, 



Sylvia atricapilla. The Blackcap. 



Occurs regularly as a bird of passage. The males were 

 very numerous here on the 6th of May, 1919, but, as 

 already remarked, the spring migration was much delayed 

 that year. 



Acrocephalns scirpaceus. The Reed-Warbler. 



In the ' diannel Islands,' by Ansted & Latham, 

 Mr. Galliene in his remarks accompanying his list of Birds 

 of the Channel Islands, says : — " I have put the Reed-Warbler 

 as doubtful for Guernsey, but I have seen a nest of this 

 bird found at Alderney." I have not myself seen this bird 

 and do not think it now breeds here. 



Phylloscopus trochilus. The Willow-Warbler. 

 A common bird of passage. I have not found it breeding 

 here. 



Phylloscopus collybita. The Chiffchaff. 



A common bird of passage, a few generally remaining to 

 breed. A few individuals wintered here during 1919-1920, 

 and so it must also be looked upon as a scarce resident. 



Turdus viscivorus. TIk^ Missel-Thrush. 



Common in winter during cold weather. L. tells ire that 

 he has found it nesting here, but I think it has almost, 

 if not quite, ceased to do so, as I have not observed it 

 during the breeding-season. 



Turdus musicus clarkii. The Song-Thrush. 

 A common resident. 



Turdus iliacus. The Redwing. 



Common in winter during cold spells, or continuous strong 

 north-east winds. At other times not often seen. 



Turdus pilaris. The Fieldfare. 



As in the case of the last species, it is common during cold 

 weather or strong north-east winds, but unlike that species, 

 it does not disappear so quickly on the weather moderating, 

 and a few may usually be met with throughout the winter, 

 even in mild weather.
