210 ADVENTURES AMONG BIRDS

 the redpoll would be far away in its breeding haunts 

 in the pine forests of the north when the warbler 

 was in the west country ? Strange to say there was a 

 small colony of half a dozen redpoll pairs breeding in

 guide to the spot had told me of these birds, and it

 Other listeners, however, have said that he does mimic 

 the blackbird's song. Then, as to the whinchat, in 

 two days' listening I heard no imitation of its song, 

 although the bird was present and building in the

 minds with an acid flavour. 



I think the imitation which pleased and surprised 

 me most was that of the willow wren's exquisite joyous
