242 THE AMERICAN MIDLAND NATURALIST. 
Sparrow. Abundant summer resident, arriving in middle or 
late March, and becoming abundant in the first week of May. 
Its nests are built in bushes, shade trees, shrubs, vines about 
houses, and in low bushes in semi-open woods. Eggs are laid 
about the second week in May. The species seems to prefer 
nesting near houses, and is very common in Charles City. 
152. Spizella pusilla pusilla (Wils.) Field Sparrow. 
A common summer resident in Floyd and adjoining counties. 
It arrives from April 4 to 19, and remains until the second or 
third week of October. The first eggs are laid about May 8. 
The species, along with the preceding, seems to be increasing 
in numbers rather rapidly. 
153. Junco hyemalis hyemalis (Linn.)  Slate-colored 
Junco. Abundant migrant and winter resident. It arrives 
in the first or second week of October and remains until about 
April 20. The spring migration is at its height in the third 
week of March, when flocks of from 40 to 400 of these birds 
may be commonly seen. 
154. Melospiza melodia melodia (Wils.) Song Sporrow. 
A common summer resident, arriving from March 17 to April 
1. It nests in May, June,.and the first part of July, remaining 
until mid-October. It nests on the ground, usually in or near 
thickets, particularly near the streams. 
155. Melospiza lincolni lincolni (Aud.) Lincoln’s Sparrow. 
An irregular and rather uncommon migrant. It usually 
arrives in the spring about April 25. On March 17, 1918, 
during an uncommonly warm period, Miss L. E. Kelley and 
myself saw a flock of 6 of these birds in Oak Park, north- 
east of the cemetery at Charles City. This is my earliest 
record for the species. 
156. Melospiza georgiana (Lath.) Swamp See A 
tolerably common migrant, but seldom seen because of its 
habits. It arrives April 2 to 10, reaching its maximum in 
8 to 14 days later than the first arrival. Passes south during 
October. Is not known to breed in the county. 
157. Passerella iliaca iliaca (Merrem.) Fox Sparrow. A 
rather irregular migrant, common some years and uncommon 
in others. Spring arrival dates range from March 27 (1916)
