The study found that female vampire bats prefer to hunt for blood with friends </ P >

<

p > vampire bats inhabit together in trees, where they can be observed combing each other’s hair and even sharing ruminant blood with hungry habitat partners. Previous studies have shown that this cooperative behavior is aimed at close relatives and social partners. In order to study whether the social relationships of bats also affect their foraging behavior, the researchers installed tiny proximity sensors on 50 female common vampire bats (Desmodus rotundus) – including 27 wild bats and 23 bats that have been kept in captivity for nearly two years – and then put them back to their wild habitat on their cattle farm in tole, Panama</ p>

p > the researchers found that although the labeled bats almost never left their habitat together, closely related female bats often reconnected far away from their habitat. Bats that contact more partners in their habitat will also meet more partners when foraging. In Panama, rajoerella recorded the calls of blood sucking bats and found three different types of calls: “sweeping down” social calls, antagonistic “buzzing” calls and “n-shaped” foraging calls. The latter was not observed in wild or captive blood sucking bats before</ p>

p > the authors speculate that bats may meet with trusted partners during foraging to share information about the host or quickly find an open ready-made wound. They speculate that this cooperation may save time and energy in selecting and preparing wound sites in cattle. They said that this downward shooting call is similar to the contact call used to identify habitat partners, and may also help bats identify friends and enemies on their wings</ p>

p > the researchers added: “how far can ‘friendship’ go? We show that the social ties of vampire bats are not limited to combing and sharing food in the habitat, but the combined individuals even hunt together, which highlights the complexity of their social relations”</ p>
