THE BIRDS OF FLOYD COUNTY, IOWA. 231 
commonly perching on cables crossing the river at Main 
street in Charles City, and they seem in no way annoyed by 
the people, vehicles and street cars. 
103. Dryobates villosus villosus (Linn.) Hairy Wood- 
pecker. A common species in autumn, winter and spring; 
less common in the summer. I have found them throughout 
the summer at Rudd, Nora Springs, Rockford, Marble Rock 
and Charles City, as well as at various localities throughout 
the county. On August 28, 1918, I identified three individuals 
at Hackberry Grove. 
104. Dryobates pubescens medianus (Swains.) Northern 
Downy Woodpecker. A common resident, particularly in the 
winter. It is more common in the towns than is the Hairy 
Woodpecker, nesting even in the closely settled portions of 
Charles City. In the country woodlands its nests are not 
at all uncommon, and I have found them in various parts of 
the county. 
105. Sphyrapicus varius varius (Linn.) Yellow-bellied 
Sapsucker. A common migrant and summer resident, most 
common in April. February 12, 1916, I saw two specimens 
in the northern part of Charles City. Most of my records 
fall between April 8 and April 20. It has nested in Charles 
City in all of the last seven years. In 1917 and 1918 it was 
found nesting at Hackberry Grove. In the summer of 1919 
a pair nested near the bridge over the Shell Rock at Rockford. 
106. Melanerpes erythrocephalus (Linn.)  Red-headed 
Woodpecker. A common summer resident and uncommon 
winter resident. H.C. Brown and I have identified them on 
January 2 and 5, 1917; I have records for January 16, Feb- 
ruary 10 and December 26, 1918. There are several other 
winter records, indicating that it is by no means unusual for 
the species to remain throughout the year. The spring mi- 
gration begins with a few scattered individuals in late March 
or early April. Numbers of arrivals gradually increase until 
the height of the migration is reached in the last week of 
April and the first of May. Mr. Webster and I have on two 
occasions noted these birds catching insects on the wing. 
107. Centurus carolinus (Linn.) Red-bellied Woodpecker. 
Rare visitant. I have one sight record for May 8, 1915. I
