Remarks.—A colony of approximately 100 of these bats was discovered in the unused portion of a barn loft at Ft. Niobrara Game Reserve on August 11, 1948. Although no temperature readings were taken, it was estimated that the temperature was more than 100° F. in the loft. The bats were congregated on rafters at the north end of the barn and when disturbed, only a few members of the colony dropped from the rafters to fly. Most of the bats crawled to new retreats between the rafters and the corrugated iron roof of the building.
