BIRDS OF CLAY AND O’BRIEN COUNTIES 
271 
106. Passerina cyanea. Indigo Bunting. Common during 
spring migration and a tolerably common summer resident. 
107. *'8piza americana. Diekcissel. An abundant breeding 
species ; nested in weeds and vines along fences. 
108. Passer domesticus. English Sparrow. Abundant per- 
manent resident. 
109. Piranga . erythrpmelas. Scarlet Tanager. Tolerably 
common breeding species. 
110. *Progne subis subis. Purple Martin. There were breed- 
ing colonies in Spencer, Everly, Sheldon, Peterson, and Webb. 
Other towns that probably had them were not visited at the right 
seasons. 
111. *Petrochelidon lunifrons lunifrons. Cliff Swallow. Lo- 
cally common throughout the territory, dusters of their mud 
nests were hung under the eaves of barns. 
112. * Hirundo erythrogastra. Barn Swallow. One or more 
pairs of these swallows could generally be found about every 
cluster of farm buildings. They occasionally nested under 
wooden bridges and were then known as “bridge swallows.” 
113. Jridoprocne bicolor. Tree Swallow. An abundant fall 
migrant in July and August. At this season great mixed flocks 
of swallows appeared to feed over the marshes. Between meals 
they rested on telephone wires and fences and often filled all the 
wires for rods. All five species here recorded were well repre- 
sented in these flocks. 
114. Riparict riparia. Bank Swallow. Nested commonly. 
115. Stelgidopteryx serripennis. Rough-winged Swallow. 
Occurred in numbers in the fall flocks. 
116. Lanius ludovicianus migrans. Migrant Shrike. A pair 
with four young just out of the nest were found near Sheldon, 
August 7, 1913. The species seemed to be generally distributed 
over the region as I noted it at Spencer, Webb and in southern 
Clay. 
117. V'ireosylva olivacea. Red-eyed Yireo. Tolerably common 
breeding species. 
118. Vireosylva gilva gilva. Warbling Yireo. Common sum- 
mer resident. 
119. Mniotilta varia. Black and White Warbler. One noted 
at Sheldon, May 14, 1910.
