Costa Rica has approximately 110 out of 1,100 species of bats. Out of all the species of mammals in Costa Rica, bats make up approximately 50% of the mammals found in the country.
There are several different types of bats, classified by their diets. Found only in Central and South American countries, there is Desmodus rotundus, or the common vampire bat, which is a sanguivore, meaning they consume blood. There are also nectarvores, which eat the nectar of nocturnal flowers and are major pollinators. Fruitivores are fruit eating bats, and finally, carnivore bats, which eat frogs, insects, fish, and even other bats. Costa Rica is home to all of these kind of bats.
In 2006 renowned bat biologist Richard LaVal opened the Bat Jungle, a world-class bat exhibit. The attraction includes a microphone that can pick up on ultrasonic sound waves, allowing their guests to hear when the bats echolocate, a bat cave with 100 bats. They have feedings scheduled throughout the day and have a small bat that cannot fly that guests can see up close and personal.
Scattered around the reception area are several posters with lots of bat information, ranging from common misconceptions to skeletal structures of popular bat species.
After one long week of no bat sightings, we finally to got to see some bats. Our tour guide impressed me greatly. He was very well informed on current bat information. During the tour he told the group about the white fungus issue happening in North America and about the nearest information on how scientists are finally able to treat bats with it. This information was released about two weeks ago, so it was very current and a good thing to share when touring with a group of biologists. Our guide took us into the bat cave, which was amazing, and held a flashlight on the bats for us to get pictures of them. He even feed them so our group could see them dive in for some watermelon chunks.
After we left the bat cave he brought out Oscar, the little bat who couldn't fly, and allowed our group to pet him to feel his tiny body shake from his rapid heartbeat. As an aspiring bat biologist, this tour was the highlight of the trip so far.
