192 WILD ANIMALS OF GLACIER NATIONAL PARK. 



iiUy the two-syllabled ta-tib' was given, but generally it was the long 

 scolding chatter. AVhen finally relieved of our presence the parents 

 expressed their feelings in various low notes followed by their sweet 

 tinkling song. The nest of the wrens is described by Mr. Stevenson 

 as " a small oven made of moss on the side of a rotten log." 



One of the winter wrens was seen by Mr. Gibb in July on Lake 

 Josephine, and Mr. Bryant, of California, when in the park heard 

 them in many places and found them "much in evidence along Lake 

 McDonald and McDonald Creek." Mr. E. S. Bryant says they are 

 common all winter. 



In April, 1918, Mr. Bailey found them " singing in many places 

 along the way," up the North Fork of the Flathead, and says : "" One 

 was living under some logs of the road grade on the Fish Creek hill, 

 where four feet of snow covered his dark, cold den. He would come 

 out and bubble away as if the flowers were blooming, then dive back 

 into the black caverns under the snow l)ank."

Rocky Mountain Creeper: Certhia fam'/lkirls montana. — The 

 little bark-colored creeper, rocking up to the top of one tree trunk 

 and then flying down to the foot of another to start over again in his 

 search for bark insects, may be easily overlooked in the dense coni- 

 ferous forest; but his small beady note on the order of the wax- 

 wings, when once heard will readily place him. Only one was seen, 

 but a number were heard during the summer in various parts of the 

 park.
