The greatest incidence of rabies occurs in the large vampire bat populations found in South America. Here the danger is not so much to the human population but rather to the livestock exposed to bat bites.
In South America a major economic problem existed when large numbers of cattle were lost to rabies and infection. An effort to control and eradicate the vampire bat was initiated in by the Agency for International Development in cooperation with the Mexican government. The U. Fish and Wildlife Service was assigned the task of studying its habits to obtain some clues for its control.
Using several different methods of nighttime surveillance, observation of the bat's grooming behavior provided the answer. Bats are extremely clean, sometimes grooming, licking, and scratching themselves for hours. The vampire bat, in particular, grooms both itself and its neighbors intensively.
A paste-like anticoagulant poison that causes internal bleeding in the bat was smeared on likely areas, fetlocks or shoulders, of cattle that had been bitten.
Vampire bats usually return to their victims for more food, so when they attack again, they come in contact with the poison.
Back at the roost in the process of grooming, they ingest and spread the poison with the subsequent death of a large percentage of the colony. The treatment is specific for the vampire bat; no other species is affected, and the anticoagulant does not appear to hurt the livestock even when injected directly into the stomach.
At the present time, the poison is being used successfully in Mexico, Central and South America. For humans, daytime brings work and play. For bats it is the time to rest in some secluded shelter, hang head down, groom, sleep, and perhaps even quarrel.
When night approaches, bat activity increases; they fly about inside their cave then finally emerge to forage for food and drink water. After feeding for an hour or two they may rest again, then have a second feeding before daybreak.
In many species, the males and females roost separately except when mating. In migratory species mating occurs in the fall and winter.
The female stores the sperm until spring when ovulation and fertilization occur. In May or June the females congregate in large colonies and give birth. Most species bear only a single young per litter, but others may have two, three, or even four. The female hangs head up as the young is born, feet first. She catches and holds the new born in the pouch formed by the interfemoral membrane. The baby bat, already large and well developed, crawls to the mother's nipples, attaches itself and feeds.
In the evening when the mother forages for food, she may, for the first few days, carry the young with her. Later the baby remains behind, clinging to the wall or roof of the cave or shelter. The mother may return several times during the night to feed her young.
Among young bats, mortality is high. Some fall from the roof of their shelter and are not able to climb back; some succumb to disease or parasites. However, they do grow rapidly and are able to fly in about three weeks. Once the hazards of youth are over, bats enjoy a relatively old age, some reaching the age of 20 and in one documented case of a brown bat, to Certainly they attain a longer life span than other mammals of similar size such as rodents that live for only one or two years.
The Smithsonian frequently is asked how to get rid of a bat or bats that invade a house or building. If a lone bat flies into your home, simply open all the doors and windows and allow it to find its own way out. If this is not successful, take a large towel or blanket, throw it over the animal, gather it up and put it outside.
The bat will extricate itself from the cloth without any additional handling. Eradicating large numbers of bats from buildings or barns is much more difficult since once they choose a place to roost, they continue to return to that site.
The best approach is to take preventive measures. Despite all the misconceptions surrounding bats, they are very important to humans and the environment. Insect-eating microbats consume millions of bugs a night, acting as a natural pest control for plants. Thanks to bats, farmers might rely less on toxic pesticides , which costs them millions of dollars each year.
Nectar-drinking bats pollinate plants so they can produce fruit. In fact, more than plant species, including mangoes, bananas, and avocados , depend on bats for pollination. Finally, fruit-eating bats help disperse seeds so rainforests can grow, helping to mitigate the effects of widespread deforestation. All rights reserved. Common Name: Bats.
