494 Mr. C. Collier on the Birch 



Dipper. Cinclus aquaticus. 



One or two pairs on every stream. Resident. 



Long-tailed Tit. Acredula rosea. 



Common and resident for the whole year. It nests in far 

 higher situations than I have noticed elsewhere. Several 

 nests were built in Scotch firs and against the trunks of 

 lichen-covered oaks at heights varying from 15 to 35 feet 

 from the ground. Large numbers of these birds, together 

 with Blue Tits, Coal-Tits, and Gold-crests, congregate and 

 hunt for food in the fir-woods during hard weather. 



Great Titmouse. Pants major. 

 Uncommon; but a few pairs breed every year. 



Coal-Titmouse. Par//*- britannicus. 



The commonest of all the Titmice; large numbers nest in 

 old stumps of trees, in Avails, and even in holes in banks. 



Marsh-Titmouse. Pants palustris. 



This bird I have only occasionally observed during hard 

 weather in the winter, generally in company with other Tits. 

 It was never seen during the summer. 



Blue Titmouse. Varus caruleus. 



Quite common ; many breed, but it is not so numerous as 

 the Coal-Tit. 



W ren. Troglodytes parvulus. 



Resident, and scattered over the whole area from the 

 highest points to the sea-shore. 



Pied Wagtail. Motacilla htgubris. 



Summer visitant, arriving in the early spring and re- 

 maining until the end of September. Sometimes I have 

 noticed a stray bird during winter about the farm-buildings, 

 but only, I think, on three occasions. 



Grey Wagtail. Motacilla melanope. 



A resident, but the majority leave in September or 

 October, only a few remaining for the whole year. Iu the 

 summer nearly every stream has its pair of birds, and one 

 stream in 1899 had three pairs on it.
