MIMICRY OF THRUSH 



201 



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.

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.
