1922] Swarth: Birds and Mammals of the Stikine Region 289 



Dendroica coronata hooveri McGregor. Alaska Myrtle "Warbler 



Apparently not common in this region, though some were seen at 

 each collecting station. At the Junction the species was first seen on 

 May 28. Two females taken on May 29 were evidently not breeding ; 

 from their actions, these birds and others seen the same day were as 

 yet not even paired. To all appearances they had just arrived. None 

 was seen in the immediate vicinity of Telegraph Creek, but a few 

 pairs were encountered at scattered points spme miles away. A few 

 were seen at Glenora. At Doch-da-on Creek, July 8 to 25, small flocks 

 occasionally appeared, sometimes a single family, sometimes evidently 

 composed of two or more broods. The species undoubtedly nests at 

 that point. Whether or not it nests at Flood Glacier, our next station 

 down stream, is questionable, though I should think it likely that a 

 few pairs might extend that far. Several specimens were taken there, 

 and others were seen, some each day. At Great Glacier, August 9 

 to 16, . Hoover warblers were seen frequently, migrating then and 

 evidently traveling down stream. At the time of our arrival at Sergief 

 Island, at the mouth of the river, on August 17, there were none of 

 these warblers present. The first was obtained there on August 30, 

 and in the next day or two the birds were arriving in considerable 

 numbers. 



We found no nests. Not many of the birds were seen under such 

 circumstances that it seemed profitable to make search, and when 

 we did attempt to watch individuals that were obviously nesting 

 near-by the results were fruitless. For one thing, the suspects we 

 selected invariably dropped all other interests in order to follow us 

 about, and, each time, the warbler we were watching proved able to 

 sit around doing nothing longer than we ourselves cared to. 



The first young bird was collected on June 18, and others in juvenal 

 plumage were taken at later dates, to July 10. One taken at Doch- 

 da-on Creek, July 22, is well advanced in the molt into first winter 

 plumage; another from Great Glacier, August 14, has just begun 

 this change. One from Sergief Island, September 1, still retains 

 much of the juvenal plumage. It is interesting to note that this bird 

 probably traveled some distance from its birthplace while undergoing 

 the molt. Another specimen taken at Sergief Island the same day 

 has practically completed the change into first winter plumage. 



Adults in various stages of wear were taken up to the end of July. 

 A female taken July 26 is in extremely shabby and abraded plumage.
