BIRDS OF N.W. WALES AND IRELAND. Ill 



an enormous amount of detail on the migration of birds, besides 

 adding several very rare species to the fauna. It is chiefly 

 owing to him that the Pied Flycatcher finds a place in the Irish 

 list, while the Lesser Whitethroat and several other birds have 

 thus been added to it. 



As it would take too much space to deal with every species, 

 I omit all those which are very rare, as well as those which are 

 equally common in both districts. In this way the whole of the 

 Thrushes may be disposed of as being common in both, though, 

 curiously enough, the Mistle-Thrush only colonized Ireland during 

 the last century. 



Whinchat. — W. Fairly common, but somewhat local. I. 

 Much less numerous ; a few breed in both counties. 



Redstart. — W. Common in the wooded districts. I. Very 

 scarce and local ; a very few breed in Wicklow. 



Black Eedstart. — W. Recorded three times only. I. Pro- 

 bably visits south and east coasts annually on migration. 



Lesser Whitethroat. — W. Local. Occurs in the eastern 

 parts of Merioneth and Carnarvon, but apparently not on the 

 west coast. I. Almost unknown ; has occurred twice on migra- 

 tion, in Donegal and Kerry. 



Blackcap. — W. Common and generally distributed in all 

 suitable districts.* I. Rare generally, but occurs in parts of 

 Wicklow and Dublin, and is increasing. 



Garden Warbler. — W. Generally less numerous than the 

 Blackcap, and more local, but occurs in most wooded districts, 

 and is plentiful in some. I. Very local, and has not been known 

 to breed in Wicklow or Dublin. 



Wood Warbler. — W. Exceedingly numerous in the wooded 

 parts of Western Wales. I. Very rare and local ; a regular but 

 very scarce summer visitant to Wicklow. 



Reed Warbler. — W. Very local in district, but has been 

 identified in several places in Carnarvonshire, whilst the nest 

 has been found three times. I. No reliable evidence of its 

 occurrence in Ireland. 



■'■ Anglesey is singularly devoid of woods, so that this and other wood- 

 land species are comparatively few. Still I have met with the Blackcap 

 there, and several other Warblers — the Sedge-Warbler and Whitethroat — 

 abound.
