BLACK BIRDS. 5 



The Chough is the only bird with pluTnage entirely 

 black and possessing bright-red bill and feet, and 

 though in j'^oung birds these are orange, even so, taken 

 in conjunction with the black phimage, they remain the 

 infalHble distinguishing marks of the Chough. In its 

 habits and vivacious temperament this bird closely 

 resembles the Jackdaw, with which it often associates 

 in its nesting quarters and feeding resorts. It nests 

 in colonies in holes in high cliffs, has a note distinctly 

 akin to the high, querulous, and somewhat nasal 

 'A-dw!' of the Jackdaw, and further resembles the 

 Jackdaw in performing concerted aerial evolutions 

 with its fellows or in company with Jackdaws, during 

 which it indulges in the ' tumbling ' antics common 

 with Jackdaws and Rooks. The Chough feeds in 

 flocks in inland fields and pastures, and searches the 

 shore for animal matter flung up by the sea, moving 

 about with a short, rapid, running motion often seen 

 in the Ma.gpie.
