BATS ON PUBLIC DISPLAY

Although television is an excellent medium for wildlife education, it cannot replace a personal encounter with a living creature. When the animal is a bat, such experiences help people overcome their fear of these beneficial creatures, and other wildlife as well.

CONDITIONING BATS FOR PUBLIC DEMONSTRATIONS
Whether a bat is wild, handraised or born in captivity, it will bite. Wild bats bite in self-defense, and handraised bats bite for a variety of reasons. For example, they may become frightened when handled by someone with whom they are unfamiliar, or when they are restrained for long periods. Large species of fruit bats (e.g., Pteropus) are also capable of inflicting deep scratches with their claws. Most bats, however, tame easily. They must be allowed the opportunity to adjust to handlers before they are used in animal demonstrations. More importantly, handlers should never demonstrate a bat until they feel confident in their ability to maintain control over the animal. FIGURES 97 and 98 show the proper methods for holding bats during demonstrations.

Some lecturers avoid handling bats altogether. They incorporate the animal(s) into educational displays (FIGS. 99-101). Although this method is less "thrilling" to the audience, it is also less stressful to the animal, and the chance of animal injury is reduced considerably.

When conditioning bats for demonstrations, handle them twice daily in a quiet, safe area. Opportune times include the morning during cage cleaning, and in the evening just before they are fed. Each taming or calming session should last from 5 to 30 minutes, depending on the individual bat's tolerance for handling.

When taming [heterothermic] bats, place the palm of the hand against the animal's body while it is resting on its perch. In this way the bat will not be awakened suddenly, causing it to bite in fear. Allow the bat to wiggle freely under the hand until it is warm to the touch. With a soft cloth, remove the bat slowly from its perch. Do not jerk the feet free of the perch and be sure the wings are folded properly under the cloth; bats are very delicate animals and their bones break easily. Once the bat is under control in the cloth, maintain that control while stroking it with an ungloved hand.

Avoid holding a bat while delivering a lecture. Rather, concentrate on maintaining control over the animal. First complete the program, then show the audience the living specimen. It is inappropriate to allow anyone from the audience to handle a bat. NEVER allow a bat to fly during a program unless, of course, it is secured in an appropriate flight cage or exhibit booth (FIG. 102) for the species. To minimize stress to the bat, limit its demonstration time to 5 or 10 minutes daily. If more than one bat is available for demonstrations, rotate them. Figure 102

People are very curious about the wings of bats. Rarely will a demonstration be completed without one or more individuals asking to see the animal's wings. Although spreading a bat's wing is not injurious to the animal, it so intensely dislikes having this done that it may become a "biter." To prevent this, either obtain a taxidermist's mounted specimen (FIG. 103), or use a photograph to show this feature.

Occasionally, bats react adversely to hand creams, perfumes, shaving lotions or other aromatic products. Avoid their use when handling any wild animal.

EXHIBITING
If displays are designed poorly, small, secretive bats cannot be seen by the public. The ideal exhibit minimizes stress for the animals by providing adequate flight distance from viewers, yet it also allows the animals to be seen. Exhibits should be sound-proofed with glass fronts. Provide conspicuous graphics instructing, "Do Not Tap on Glass". An exhibit design which has proven successful for big brown bats is depicted in FIGURES 104 to 105. This exhibit is also suitable for other species that roost in bat houses.

It is not uncommon for fighting to occur between males of many bat species. The ideal sex ratio for compatible coexistence among most captive colonial bats is one male to approximately 8 to 12 females. To prevent injuries, provide an appropriate number of retreats for subdominant animals, or remove them entirely from the exhibit. Off-display caging can be constructed as described in Chapter 5, ENVIRONMENT AND HOUSING FOR ADULT BATS.
