300 BIRD WATCHING 



Kwubba-wubba. 



Ow (prolonged, a peculiar musical piping note). 



Polyglot (or something remarkably like it). 



Quar-r-r-r. 



Quor-r-r-r-r-r (very prolonged, and deep, as in 



remonstrance). 

 Quow-yow, or yow-quow. 

 Shook, shook, shook (soft and quickly repeated. 



Have heard it uttered by rooks when flying 



home belated, after the great majority had 



settled in the roosting-trees). 

 Tchar. 



Tchar-r-r (with a little roll in it). 

 Tchu or tew. 



Tchoo-oo (very deep and guttural). 

 The peculiar "burring" note (uttered, but by no 



means always, when the birds swoop down 



on to trees, especially the roosting-trees. It 



is not heard very frequently). 

 A peculiar sound like a kind of bleat, with a very 



complaining tone in it. 

 A short, sharp, single note, much higher than the 



ordinary caw. 

 A kind of grating scream, much higher than the 



usual tone. 

 A hoarse "mew," or "miaul" almost, as though a 



rook were trying to imitate a cat, or a cat 



a rook. 

 The liquid castanet-note in the throat, suggesting 



the "burr," but not quite it. 

 Various other curious little sounds in the throat, 



some of them clicks.
