KILBUCK AND AHKLUN MOUNTAIN BIRDS 



135 



Generally, the abundance of most breeding or probably breeding 

 species was similar throughout the areas where they were recorded on 

 our study area (Table 10). Exceptions included the rough-legged hawk 

 (rare in the Kilbuck Mountains and common on the coastal plain), the 

 least sandpiper (rare in the Kilbuck Mountains and uncommon in the

 59% of the breeders were abundant to fairly common in the Kilbuck and
