This, the largest bird of its family occurring in 

 Pennsylvania, is found here as a resident. In the 

 summer season Ravens rarely leave their native 

 heather where, in a region abounding in stately forest 

 monarchs and precipitous rocky cliffs, they can rest in 

 comparative safety from enemies, especially man 

 whom they dread the most of all. 



MUST WATCH THE FOX. 



Sometimes when Ravens nest on rocky ledges or in 

 caverns in the mountains, as they do very often, their 

 eggs or vioung are taken by Poxes or Wildcats. If 

 Ravens build in a locality which they find is accessible 

 to the cunning Fox or sneaking Wildcat they abandon 

 the place, and if no suitable nesting site can be found 

 on some high rocky place inaccessible to these and 

 other carnivorous animals, they build high up in tall 

 trees, selecting usually the white pine. 



THE NEST AND EGGS. 



The nest of the Raven is a rude structure composed 

 largely of sticks, twigs, moss and bark.
