Overview 

Natural History Information 

Range and Habitat 

  • The straw- colored fruit bat can be found throughout Africa in tropical forests, savannas, and any other area that contains many trees and enough food.
  • They most commonly roost in trees during the day but can also be found in caves and lofts.

Longevity 

  • Native habitat: 15 years
  • Under human care: up to 21 years  

Ecosystem Role 

  • Because they eat fruits and flowers, these bats are important pollinators and seed dispersers.

Husbandry Information

Diet Requirements

  • In their native habitat, these bats eat leaves, flowers, nectar, pollen, and fruit juices. They chew fruit into a pulp, swallowing the juices and spitting out the remaining fruit. They chew on bark to get water.
  • Akron Zoo: our bat diet is a mix of Mazuri softbill pellets, Zupreem canned primate diet, and fresh fruits and greens.

Weight Management

  • Akron Zoo: bats are weighed every other week.

Threats and Conservation Status

  • Threats facing this bat are deforestation and hunting for bush meat and medicinal use.
  • Preyed upon by snakes, birds of prey, and humans.

Interesting Natural History Information 

  • Straw- colored fruit bats are very social and roost in groups between 100 thousand to 10 million individuals! When food becomes limited, the colonies will move to where there are more feeding options.
  • Since they live in such large colonies and like to eat fruit, they can be harmful to crops. In some instances, this can outweigh the benefits of seed dispersal and pollination.
