“ It was common to see several bats of this species, not in a cluster but with a few inches of space between any one bat and its neighbors, on the vertical screens that covered the airways beneath the eaves of the buildings. A colony was established in Zetek House (a trail-end house on the western side of the Island) , and several individuals often were seen in the Tower House. As many as 50 individuals could be found at the Van Tyne Big Tree (Bombacopsis Fendleri) where they hung singly in the shaded inter-buttress spaces and on the exposed trunk sometimes up to a height of 100 feet. ”

“ On Barro Colorado Island one aim is to preserve the biota and natural conditions with as little interference from man as possible. Consequently most of the bats captured were released after being wing-banded by Jackson with U.S. Fish and Wildlife Service bat bands; but an attempt was made, with the permission of Mr. James Zetek, Resident Custodian of the Canal Zone Biological Area administered through the Smithsonian Institution, to save one or a few specimens of each species for positive identification. ”

“ Jackson found this species to roost between the corrugations of the metal roof and the underlying wooden supports. He banded 14 individuals, most of which were pulled with forceps from their resting places in the old laboratory or the kitchen. All were males. Five were recaptured from one to 13 days after banding, and two were found in the places from which they originally had been plucked 13 days previously. Enders (op. cit.:421) found this species to be abundant about the laboratory where it spent the day hanging under the eaves. ”
