THE NEST ON THE GREY CRAG 113 



concealed amongst the thick ivy, and the 

 few sticks which may project above the 

 ledge are difficult to spot as we climb 

 about the face of the cliff. Incubation 

 lasts three weeks, and as soon as the 

 young appear the old birds are very bold, 

 and show instant fight if any other large 

 bird should go near their home. I have 

 seen many a fight between a Buzzard and 

 an angry Raven, and the Raven is usually 

 victorious. Near one nest that I found, 

 a Rock Dove had her nest, and when the 

 young Ravens appeared on the scene, the 

 Dove had very great difficulty in getting 

 to or from her nest, for the instant she 

 showed herself the male Raven would 

 dash after her, and with his great wings 

 hissing as he cut through the air, chase 

 her for a mile down the valley. Time 

 after time I saw her making attempts to 

 reach her eggs, but he went at her in a 

 most desperate manner each time she 

 appeared.
