[Ibis, 
Major W. R. Thompson on the 
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. 
Acrocephalus scirpaceus. The Reed-Warbler. 
In the 4 Channel 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. The 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.
