Abstract

Available literature on the Cliff Swallow (Petrochelidon lunifrons) indicates that at present this species is not as abundant as it was formerly and that no very large colonies have recently been reported from Iowa. A colony worth reporting is located five miles northwest of Oxford, Johnson Co., Iowa. A large barn with its wide eaves has served as a supporting structure for their mud nests for many years. The fact that most of the nests were on the east side of the barn was due, perhaps, to the proximity of a creek in the barnyard. On this side the writer counted 986 nests, while the number on the other side was only thirty-one. Altogether there was a total of 1,017 nests, the largest colony extant in Iowa or the middle-west. In a few places they extended nine nests down on the east side of the barn and in almost every case each was plastered to several others.
