Sialia currucoides (Bechstein). Mountain Bluebird 



There were two or three pairs in the town of Telegraph Creek, 

 presumably nesting about some of the buildings. A few others were 

 seen within a radius of ten or twelve miles, usually around small clear- 

 ings, where there had been some attempt at cultivation of the ground, 

 or in burnt-over areas, where fire had swept away most of the large 

 timber. 



Two nests were found. On June 14 a set of four eggs (no. 1829), 

 about half incubated, was taken. The nest was in an old woodpecker 

 hole in a dead birch stub, eight feet from the ground. This was near 

 the shore of Sawmill Lake, on a slope that had been lumbered and 

 burnt over, so that it was nearly cleared of large trees. A second nest - 

 was found in another birch stub nearby, a trunk that was occupied by 

 a pair of tree swallows, as well as the bluebirds. This nest on June 

 17 contained four newly hatched young and one egg about ready to 

 hatch. 



Curiously, no bluebirds were seen near Glenora, though the open 

 fields and old houses were features that should have attracted them, 

 and the species undoubtedly does occur thereabout at times. On July 

 23 a small flock was seen at timber line, about 4000 feet altitude, above 

 Doch-da-on Creek, apparently the beginning of the migratory move- 

 ment at the close of the nesting season. I have seen specimens of the 

 mountain bluebird taken at the mouth of the Stikine River on April 10, 

 1919, in migration, by E. P. Walker. 



Ten specimens preserved (nos. 40333-40342), three adult males, 

 three adult females, and four iftewly hatched young preserved in alcohol.
