MOUNTAIN BLUEBIRD (Sialia currucoides.) 



This exquisite bird, sometimes called Arctic or^Rocky 

 Mountain Bluebird, belongs to the mountains and the intermoun- 

 tain plateaus. It is found within the State, therefore, only in 

 :he Black Hills and in the badland areas. It lacks the chestnut 

 breast of its eastern cousin and is of a lighter blue. On seeing 

 this bird for the first time one goes into transports of delight. 

 It is like a winged bit of sky from the snow crowned peaks 

 where the sky is purest. And, as though to accentuate its beauty, 

 it has a delightful habit of poising like a Hummingbird on 

 wing while watching for insects in the grass.
