MIMICRY OF THRUSH 



the reproductions were exact. In fact, throughout 

 the ensuing tables the imitations numbered as exact 

 must be read as being extremely well performed 

 by the respective singers ; for some birds, such as 

 the starling and sedge-warbler, are habitually very 

 accurate in their mimicry. 



1 This note is an upwardly-slurred whistle, similar to, but more pro- 

 longed than the alarm called warblers' tewy. I have heard it commonly 

 uttered by hen greenfinches disturbed by some rapacious bird or beast 

 near the nest. It is also uttered by the redpoll.
