Zonotrichia albicollis (Gmelin). White-Throated Sparrow 
A common migrant, arriving in the spring about the second 
week in April. In 1913 the fall migration began on September 13, 
and by the 17th the birds were common and in full song. 
Spizella monticola monticola (Gmelin). Tree Sparrow 
A common migrant and winter resident, found usually in large 
rocks about hedges and brush-piles. Arrives early in November 
and leaves by the middle of April. 
Spizella passerina passerina (Bechstein). Chipping Sparrow 
A common summer resident, nesting in suitable locations. In 
1913, a pair nested in a small bay tree at the side of a busy road, 
and were perfectly fearless. The young birds were fed largely on 
the “cabbage-worm” — the caterpillar of Pieris rapae. 
Spizella pusilla pusilla (Wilson). Field Sparrow 
A common summer resident and nesting species. Greatly 
imposed upon by the cowbird. Arrives early in April, and leaves 
by the end of October. 
Junco hyemalis hyemalis (Linnaeus). Slate-Colored Junco 
A common migrant and winter resident, found along with the 
tree, fox and white-throated sparrows. 
Melospiza melodia melodia (Wilson). Song Sparrow 
A very common summer resident, a few individuals remaining 
over the winter. Nests usually on the ground, but by no means 
always. A pair raised its family among the flower-pots of a 
green-house, and the female could be stroked while incubating. 
Suffers greatly at the hands of the cowbird. A young cowbird, 
just hatched, was placed in the nest of a song sparrow, when 
all but one of the young of that species had left the nest. The 
foster parents seemed not a bit surprised at this sudden and 
unexpected addition to their family, and spent two busy weeks 
cramming that cowbird full of “cabbage worms.” Undoubtedly 
raises at least two broods a season under normal conditions. 
Melospiza georgiana (Latham). Swamp Sparrow 
A common summer resident, found breeding in all suitable 
places. Arrives early in April, and remains until after the first 
severe frosts.
