1922] Swarth: Birds and Mammals of the Stikine Region 307 



Ixoreus naevius naevius (Gmelin). Varied Thrush 

 Seen on Sergief Island at various times during our stay there 

 (August 17 to September 7). The subspecies is, of course, a sum- 

 mer visitant and reasonably abundant throughout the coast region of 

 southeastern Alaska. One specimen was collected (no. 40332), a young 

 male, just beginning to molt into first winter plumage. 



Ixoreus naevius meruloides (Swainson). Northern Varied Thrush 



There were no varied thrushes in the immediate vicinity of Tele- 

 graph Creek, nowhere in the river valley at least. We were constantly 

 - on the lookout for them, and both the birds and the call notes are 

 sufficiently conspicuous to be readily detected by any one familiar 

 with the species. Subsequent experience farther down the river leads 

 me to believe that they probably breed at higher altitudes throughout 

 the region ; we ourselves, found them at but one such station. 



At Glenora, early in the morning of July 1, the call note of a varied 

 thrush was heard distinctly, several times repeated. The bird was in 

 thick shrubbery at the river's edge, and could not be seen. It was 

 assumed to be a wandering individual, finished with family cares and 

 straying from the breeding ground on the nearby mountains. On 

 July 11 a male varied thrush was seen on the mountain side above 

 Doch-da-on Creek, at about 3000 feet altitude. The bird was perched 

 high on a dead spruce stub, a hundred feet or more above the ground, 

 uttering at frequent intervals the disconnected notes comprising the 

 song of this species. Later on others were seen or heard at about the 

 same elevation. 



On July 18 a young bird was seen at the level of the Stikine River, 

 at Doeh-da-on Creek, and from then on a few others were observed 

 from time to time. There were a few in the woods at Flood Glacier 

 and at Great Glacier, exceedingly wary and most difficult to see. Three 

 specimens were collected at Flood Glacier (nos. 40328-40330), an adult 

 male and two juvenal females; and one at Great Glacier, an adult 

 female (no. 40331). These birds are all referable to the interior sub- 

 species, Ixoreiis n. meruloides.
