57. Passerculus sandwichensis (Gmelin) Savannah Sparrow 
On May 4 Savannah sparrows noted at Ketchikan. Two days later one 
travelled all day on S.S. Alaska. A specimen, only one seen, taken at 
McCarthy May 11. Species next seen near Barnard glacier May 27, 
when three or four birds holding to scanty cover of edge of river flat, led a 
merry chase for some time before a specimen could be secured. Dis- 
appeared from the Chitina at this date, but appeared again as a migrant 
in late July movement when one or two seen. 
Specimens: Male, McCarthy, Alaska, May 11. Female, May 27. 
Writer has long noted a slight difference between Canadian Savannah sparrows east and 
west of Rocky mountains. Former slightly paler (greyer) on back, latter ruddier, with 
striping above and below more defined, ample, and stronger, with a yellower eyebrow and 
yellow suffusion over face. These Mount Logan birds agree with plains birds rather than 
with those from British Columbia. Difference slight and until a more complete study made 
of whole species seems better to include these birds under P. s. alaudinus, although doubts 
may be expressed as to application of name to many of specimens generally associated 
with it. 
58. Zonotrichia leucophrys (J. R. Forster) White-crowned Sparrow 
This sparrow one of commonest birds of region and fitted into any 
habitat from scanty thickets of Shepherdia on gravelly river fiat, to last 
willow clumps above timber-line. Common at McCarthy and all way 
en route to mount Logan; air laden with its cheery song. Though found 
wherever there was cover, its favourite location burns and more open 
country. No other bird here occupied such an extensive vertical range, 
unless perhaps the pileolated warbler which, however, was not numerous. 
A female taken May 28 had an egg almost ready for laying. First 
fledgling out of nest seen June 24 — this at river-level. Song ceased 
abruptly in mid-July- — as indeed it did with other singing birds. A few 
white-crowns seen at timber-line August 6, but at this time bulk of species 
at river-level. At time of leaving upper Chitina, these sparrows com- 
bining with flocks of j uncos, myrtle warblers, water-thrushes, and other 
shrubbery frequenting birds. 
Specimens: Male and female, McCarthy, Alaska, May 11. Five adults, May 21 to 
June 26. Three juveniles, July 4 to 21. 
Adults all straight Z. 1. gambeli. Juveniles inseparable from Z. coronata or Z. 1. leucophrys 
by characters identified as gambeli by their association with adults. Writer does 
not care to pass upon question as to whether Gambel’s sparrow should be accorded full 
specific value as has been proposed and for which there seems considerable supporting 
evidence. 
59. Zonotrochia coronata (Pallas) Golden-crowned Sparrow 
Bird not observed on the Chitina at any time, though a single speci- 
men, only one seen, taken at McCarthy, May 11. 
Specimen: Male, McCarthy, Alaska, May 11. 
60. Spizella monticola (Gmelin) American Tree Sparrow 
On morning of May 27, near camp, a fine, ringing sparrow song that 
suggested sweetness and power of a fox sparrow, heard at a willow-grown 
point of river bank. Song traced to a bird almost certainly a tree spar- 
row, but it could not be secured. Heard here once again a few days later, 
and then no more.
