HINDS OF IMIKY AND TFIK HAVEN 217 



though no collision may actually take place, yet 

 the fact that the Raven, when it turns to face 

 its adversary, is obliged to drop the stiek which 

 it carries, is not only an indication of the 

 character of the struggle, but it shows that a 

 definite end is gained that the efforts of the 

 Haven to build in that particular locality are 

 hampered. But the Falcon is not the only 

 enemy that the Raven has to face ; Buzzards 

 are just as intolerant of the presence of Ravens

 the birds are on the wing ; the Buzzard rises to

 stoops at the Raven below, and when within a 

 short distance of its adversary, swerves upwards 

 and gains a position from which it can again 

 attack. The Buzzard, however, is by no means 

 always the aggressor ; I have watched one so 

 persistently harassed by a Raven that at length 

 it left the rock upon which it was resting and 

 disappeared from view, still followed by its rival.

That there is constant warfare between the 

 Green Woodpecker and the Starling is well 

 known, the purpose of the Starling being to
