BRITISH MAMMALS 
difficulty of distinguishing this small species when on the wing from 
the Pipistrelle or Common Bat. 
More recently the alertness of various naturalists has shown that it is 
plentiful in some localities. 
In England it is numerous in various parts of the southern, western 
and midland counties, and also in Yorkshire, though rare or absent in 
East Anglia, Durham and Northumberland. In Wales it is not uncommon. 
There are only two records of its capture in Scotland, namely, one 
near Rannoch, Perthshire, in June 1874, and another at Dunbar, East 
Lothian, 20th March, 1893. It is widely distributed in Ireland. 
The habits of the Whiskered Bat seem to have been less closely 
watched than those of most of the other species inhabiting our islands. 
It has been supposed to be less sociable in its manners than others, 
though R. F. Tomes [Vict. Hist., '■Worcester') mentions a colony of 
more than a hundred in the roof of his house at Littleton. It often 
frequents the neighbourhood of rivers, where it has been observed seeking 
its prey among the branches of trees or flitting over the surface of the 
water, while it is said to have been more often noticed hawking during 
daylight than other species.
