Five “AnaBat” detectors were set up around our site and they recorded the echolocation sounds that the bats made and the information was later downloaded and interpreted.Īlthough no pallid bats have been detected on Sweetwater Marsh so far, there are 10 other species confirmed to be in the area including some that are a California species of special concern. To find out what bats are in the area, the researchers use sounds to identify the different species. With our partners at the San Diego Natural History Museum, a project has been in place for over a year to try to detect a species of bat called the pallid bat ( Antrozous pallidus). The big question you might have is that since bats are so hard to find, how do we know what species are in an area? How do we study them? The Living Coast Discovery Center is involved in a project that will help answer this question and allow us to learn more about the bat populations on Sweetwater Marsh. It is a way for bats to visualize their surroundings without any light to see by. They emit a sound from their mouth or nose and that sound then bounces off an object and is reflected back to the ears of the animal, and that animal can then sense what is in front of them, how big it is, if it is moving, etc. It is what allows bats to navigate and find food in the dark. Observers have concluded, for example, that some 100. More than 1,200 species are currently recognized, and many are enormously abundant. This ability, coupled with the ability to navigate at night by using a system of acoustic orientation (echolocation), has made the bats a highly diverse and populous order. dolphins) use to help detect food or obstacles in their path. bat, (order Chiroptera), any member of the only group of mammals capable of flight. You will often see bats flying in groups using “echolocation” to find their food and navigate their surroundings.Įcholocation is a special adaptation bats and some other animals (eg. So you need to look for places that insects might gather – the tops of trees, clearings, open spaces around a water source, etc. You need to know where to look first! 21 of the 23 species of bats in San Diego eat insects (“insectivores”). But if you stay up all night, it doesn’t guarantee you will see a bat. To contrast, animals that are awake in the day are called “diurnal”. Firstly, bats are “nocturnal” meaning they are active throughout the night from dusk to dawn. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night. Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. With 23 species found in San Diego County, you might be wondering where they all are. Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals. They are the only mammals capable of true flight: introducing the BAT! At dusk and throughout the night until dawn, the owls aren’t the only ones awake! They share the sky with a truly unique nocturnal mammal that most people know of but are rarely seen. Have you ever wondered what it would be like to fly like a bird? Well, birds aren’t the only flying animals we see in the sky.
