540 GEOLOGICAL SURVEY OF CANADA. 
A few are found in holes of trees or in logs in fences. The materials 
used are grasses, bark and leaves with finer grass or hairs as lining. 
Eggs may be found from April to August at Ottawa. (Garneau.) 
581b. Mountain Song Sparrow. 
Melospiza cinerea montana (HENSHAW) RIDGW. 1901. 
Not uncommon near the International boundary between Trail 
and Cascade, B.C., in June, 1902; they seemed to be breeding on 
the mountains; saw one at Fernie, B.C., April 22, 1904, and several 
at Elko, May 9; found a nest with four eggs quite fresh in a clump of 
brush on the side of a spruce tree about four feet from the ground. 
Nest made of grass, lined with fine grass mixed with horse hair; 
observed at Midway, Meyer creek and Sidley, B.C., in 1905, and 
breeding at Osoyoos lake and Similkameen river. (Spreadborough.) 
58le. Rusty Song Sparrow. 
Melospiza cinerea morphna (OBERH.) RIDGW. 1901. 
Regular summer visitor. (Lord.) Common in British Columbia 
west of Coast range; specimens taken at Ashcroft in the interior 
are of thisform. (Séreator.) An abundant resident confined chiefly 
to the coast and Vancouver island. (Fannin.) An abundant 
resident at Chilliwack. Tolerably common winter resident at Lake 
Okanagan, B.C. (Brooks.) The distribution of guttata in Wash- 
ington and British Columbia is singularly uniform in all kinds of 
localities, no difference between coast and interior individuals being 
apparent. (Rhoads.) Breeding from extreme southern portion of 
Alaska through British Columbia, including Vancouver island, to 
Oregon. (Ridgway.) Saw what I took to be this form in the valley 
of McLennan river, west of the Rocky mountains and south of. 
Yellowhead pass, in B.C., July, 1898; not uncommon at Revelstoke, 
B.C., in April, 1890. Further west, it was found common at Sica- 
mous and Kamloops, in 1889; not common at Penticton, B.C., a 
few pairs breeding; it was very abundant, however, west of the 
Coast range at all points visited and was particularly abundant on 
Vancouver island. Except at Revelstoke, it was found breeding 
throughout its range; like the eastern song sparrow it likes to breed 
near water. (Spreadborough.)
