GIANT CACTUS OR SAGUARO. PAPAGO SAGUARO NATIONAL MONUMENT. 



The giant cactus is a conspicuous feature of the landscape over much of southern Arizona. 

 In the absence of trees it is used for nesting purposes by woodpeckers and other hole- 

 dwelling birds. The fruit, seen growing at the ends of the arms, is eaten by many species 

 of birds.
