An Automatic Bat-Collecting Device
Constantine DG. 1958. An Automatic Bat-Collecting Device. The Journal of Wildlife Management. 22(1):17-22
Preliminary experiments by the author disclosed that flying bats of the genera Myotis, Lasiurus, and Tadarida, when released in a room for the first time, apparently failed to detect a grid of taut 0.006-inch wires arranged vertically and spaced 1 inch apart. Bats would fly into the grid, slide down the wires, and fall into a receptacle at the bottom of the grid. However, the larger bat species occasionally broke the wires, and since it was soon determined that Tadarida and Lasiurus, which are of particular interest in the bat rabies study, could be trapped indoors by wires of a greater diameter, 0.012-inch, the later size was employed thereafter. Further development resulted in several varieties and uses of bat traps, as follows." The body of the report discusses different capture methods for bats and when it is appropriate to employ each. Some of the work was done at Carlsbad Caverns National Park.
