67. Vermivora celata (Say) Orange-crowned Warbler 
On morning of August 12 well-known orange -crowned warbler 
song came from spruces beside tent. Fully a dozen songs heard, 
which seemed remarkable, as song season long past. Bird seen, 
but escaped. Later in day, while decoying some warblers — mainly pileo- 
lated — on river bank nearby, an orange-crown darted up, almost perched 
upon point of gun, then suddenly flittered away and disappeared in 
poplars and willows. Which form of bird seen cannot be stated. 
68. Dendroica aestiva Yellow' Warbler 
Observed but once, when on rainy morning of July 8 a singing male 
delivered a song or two beside tent and then fled. Bird seen, but 
could not be secured. 
69. Dendroica coronata (Linnaeus) Myrtle Warbler 
One of half-dozen really common birds of region, found everywhere 
in timber. At McCarthy May 8 and common all w'ay to Hubrick’s camp. 
Its song, “Weeee-weece-weece-weece, wichy-wichy-wichyV 1 ever ringing from 
spruces, and males delivering it very shy. Usually they sang from a 
high perch. Species most common at river-level, though found to limit 
of trees. 
No nests discovered, though a pair of birds that played cripple in 
spruce w'oods, June 30, evidently giving a clue to a nest. However, no 
amount of search, even where pair seemed most frantic, could reveal secret. 
Small flocks of myrtle warblers and j uncos met commonly at time 
of breaking camp — young of both species being vastly more numerous 
than adults. 
Specimens: Male, McCarthy, May 11. Four adults, May 27 to June 14. Two 
juveniles, July 19. 
These birds show prescribed characters of H. c. hooveri, long wing (over 3 00 inches 
instead of under), slightly pale yellow, and averaging slightly less black below than eastern 
specimens, but to so slight a degree that it is doubtful if they would be recognized as such 
were it not for geographical suggestion. Those who have regard for such fine distinctions 
would call them hooveri , but writer hesitates to separate them from D. c. coronata. 
70. Dendroica striata (J. R. Forster) Blackpoll Warbler 
Tw'o individuals taken near camp, August 12 and 13, both juvenal 
females, only ones seen. 
Specimens: Two juveniles, August 12 and 13. 
71. Seiurus noveboracensis (Gmelin) Northern Water-thrush 
A small migration of these birds came to upper Ghitina August 12. 
Four juveniles taken and a few more seen, nearly all in moist habitat at 
river-level. One seen to perch high in a spruce tree, a remarkable denial 
of habit. 
Specimens: Four juveniles, August 12 to 14. 
In a collection of over eighty specimens from widely scattered localities in Canada, 
many of which have been identified as nolabilis by competent authority, less than six can 
be said truly to have “white (below) with little or any tinge” as postulated by Ridgway 
for that race. Differences of colour of yellow below or of olive above do occur throughout 
species, but series, when proper age, sex, and season compared, so inextricably mixed 
geographically on both migration and breeding dates as to make it seem hopeless to demon- 
strate distinct distribution to two extremes — noveboracensis and nolabilis. 
These Mount Logan birds happen to be amongst birds sootier on back and with only 
moderate amounts of yellow below. By diagnosis they, therefore, can be referred to S. n. 
nolabilis.
