284 BIRD BEHAVIOUR 



denounced our nearly-allied Great Grey Shrike 

 (Lanius excubitor) as an " ungratefull subtill fowle " 

 for the same treacherous manoeuvre. 



But it is curious that such imitative birds do not, 

 when wild, generally copy human speech, though I 

 have myself come across a case which seemed 

 very like it ; when living a few years ago just north 

 of Regent's Park, I used to hear a voice in the very 

 early morning outside my bedroom saying " Pretty

 the talker to be a wild Blackbird, which came to 

 sing his matin song which, as every observer

 he had probably picked them up at some time from 

 a Parrot, for the Blackbird is at times imitative, 

 though not nearly so much so as the Starling or 

 Sedge- Warbler, or even the Song-Thrush. If the

I do not know that the well-known and celebrated 

 black talking Hill-Mynahs (Eulabes) of the East 

 exercise any mocking faculty when wild, but if 

 they do not it would be nothing wonderful, con-
