61. Junco hyemalis (Linnaeus) Slate-coloured Junco 
Common almost everywhere, breeding from river-level to timber- 
line, but unlike Gambel’s sparrow did not continue in alpine willow thickets 
beyond. No sound more common in June than Junco trill and birds 
timed that gave twelve songs a minute. 
Juncos clever at hiding their nests, sharp warning “Chip!” of male 
apparently always calling female from nest at approach of danger. Alarm 
notes of male and female always different; male’s note “Chip!”) female’s 
corresponding call “Tseep!” this verified several times. First fledgling 
seen abroad June 17. On June 20 another fledgling taken from talons of a 
hawk owl. Yet on this same date a junco nest discovered with only one 
egg in it. Nest in a hole in a matting of bearberry on a very steep slope 
and beautifully lined with sheep hair. The one egg white with faintly 
bluish tint and marked toward the larger end with small, brownish spots 
and specks. 
On July 2 young juncos seen entirely independent of their parents. 
By July 21 juncos and myrtle warblers rather constant companions, about 
twenty birds being common in these strangely mixed congregations. 
Specimens: Adult male, McCarthy, Alaska, May 11. Adult male, May 22. Three 
juvemles, June 2 to July 21. 
The two adults cannot well be classed as anything but straight J. h. hyemalis. May 
22 bird does show a slightly dark head as called for by Cassiar junco (Swarth, Birds of 
the Stikine Region, Univ. of Cal. Pub. in Zook, vol. 24, No. 2, 243-253), but no more so 
than many eastern specimens. Other adult generally dull-coloured and looks more like a 
female than a male. Juveniles too young to be seriously identified, though one, a female, 
July 21, has considerable red on back and incoming first winter feathers on flanks are ruddy 
E ink enough to suggest an infusion of shufeldti or oregonm blood as understood in Check- 
ist. 
62 . Melospiza Iincolni (Audubon) Lincoln’s Sparrow 
Observed only once, August 12, when a juvenal female taken in 
brushy cover of a portion of river fiat where an overflow stream made a 
damp habitat. Another bird formerly suspected near timber-line, August 6. 
Specimen: Juvenile, female, August 12. 
By geographic presumption it might be expected that this bird would be M. 1. striata, 
but writer finds it indistinguishable from birds in similar plumage from Alberta and Ontario. 
63. Petrochelidon lunifrons (Say) Cliff Swallow 
Not observed on the Chitina. Two or three pairs nested about 
buildings at McCarthy. One nest rather unusual in that it was built 
on a beam inside building, birds entering through a small hole. This 
not a brood nest, but a rest nest?— wide of mouth and without lining, this 
trait having been noted in other colonies elsewhere. Birds still in vicinity 
August 22. 
64. Tachycineta thalassina (Swainson) Violet-green Swallow 
Violet-green swallows had reached McCarthy before arrival of party, 
or about May 5, and on 8th were prospecting Capt. Hubrick’s bird houses. 
Two observed May 13 at Young creek and on May 25 had reached 
upper Chitina. Soon a flock on hand and in possession of Hubrick canyon. 
Nests judged to be in abrupt face of a gravelly wall of canyon, birds being 
seen often going in and out of crevices here. Very busy feeding their
