it seen by us beyond Lat. 57°. (Azchardson.) North to Fort Good 
Hope on the Mackenzie River. (oss.) This species breeds in 
the forest and to the border of the “‘ barrens ” where several birds, 
nests and eggs, were secured; the nests were always on the ground 
and made with fine hay lined with deer hair. (Macfarlane.) 
This is one of the rarest sparrows visiting Behring Sea; it is, 
however, much more numerous in the interior and is found along 
the entire course of the Yukon at the mouth of which it breeds ; 
it extends its summer range along the Norton Sound shore of 
Behring Sea and the coast of the Arctic about Kotzebue Sound, 
yet there is no record of it having been taken on the coast of 
southeastern Alaska, nor does it occur on any of the islands of 
Behring Sea. (Velson.) This species is rarely common at St. 
Michael; it is seen only in May and November. (Zurner.) This is © 
a straggler at Point Barrow, only one specimen being taken on 
May 24th, 1883, which wasa male. (Murdoch.) »At the time of 
our arrival at our winter camp on the Kowak, and up to the gth 
September, juncos were seen nearly every day, though not more 
than five at a time ; they were always met with in the deep spruce 
woods; the last were seen on the 12th September; in the following 
spring they were noted on the 23rd May; they were never 
numerous, two pairs being the most that were seen in half a day’s 
hunt ; this species was not noted further down the Kowak than 
near the mouth of the Squirrel River, where a pair was seen on 
June 8th. (Gvinnell.) Common at Hope on Cook’s Inlet, Alaska, 
in August, 1900. (Osgood.) Five specimens were taken on the 
Kenai mountains, and at Homer, Alaska, in August and 
September, 1901; the breeding ground of this junco was in 
extensive alder patches just above timber line; they were quite 
common and were found in all such localities visited. (Chapman.) 
From Log Cabin on the White Pass, to Circle City in Alaska, 
this bird occurs everywhere. The slate-coloured sparrow, Gam- 
bel’s sparrow and the western chipping sparrow were most 
common about heaps of brush left by lumbermen, weed-grown 
clearings resulting from forest fires and cabins of the towns. 
Every nest was sunk in the ground to the rim in an open place 
under a weed or tussock of grass. One contained a few dark 
hairs besides the usual fine grass lining. (Béshop.) 
BREEDING Nores.—The nesting season of this species in New 
Brunswick is May and June. From three to five eggs are laid in
