Radar - Echolocation - Vision & Habitat
Bats really do not have “Bat
Radar”; instead they
use what is called “Echolocation”.
Similar to radar, the bats emit very high frequency vocalizations
mouth and sometimes nose as it flies.
Humans cannot hear these
bat vocalizations, which are reflected back to the bat as
it flies as an echo. This echolocation is so precise that not
only can the bat navigate a Bat Cave in
complete darkness, but can actually identify and locate the
their insect prey in flight. If a bat's ears get injured
or clogged they are unable to receive the reflected echoes,
thus lose their ability to echolocate.
A cool thing about
Bat Echolocation is that New World Fruit
Bats and Vampire Bats have
drastically reduced echolocation abilities. Nature is amazing
and seems to give exactly what is needed to survive.
Since these bats do not feed on insects they do not need
as highly advanced echolocation anatomy. In fact, these
fruit eating bats and blood drinking bats emit about 1/1000th
amount of sound energy, as do bats that feed on flying
insects, floating aquatic insects and even fish.
Bat Vision is variable
among the different bat species. The Old World Fruit Bats like
Flying Foxes (Pteropodidae) rely
on vision much more than other bat species, especially the
insectivorous bat species. Which makes allot of sense, as these
creatures need to differentiate different degrees of ripened
fruit that make up the majority of their diet.
Bat Habitat is as diverse
as the Order Chiroptera itself. Bats sleep in crevices,
hollow trees, in the open,
leaves and of course in bat caves. Bat Hibernation only
occurs with bats living in the cooler habitats.
Of all the 1000 + species of bats described
today they can be categorized into 6 types based on the type
of bat feeding behavior. These 6 categories are Fish Eating
Bats, True Vampire Bats, Carnivorous Bats, Insectivorous
and Flower Eating Bats.
David and I hope this short bio on
the amazingly diverse group of adaptive mammals called the
bats. It is our greatest hope
to create an interest in wildlife education and wildlife conservation.
We hope you take the time to enjoy the numerous high-tech Animal
Web Cams placed inside the Sanctuary’s Big Cat and
Endangered Lemur habitats. In addition, we are adding new content
to our “Education Center” on
a regular basis. We encourage you to visit them often to keep
David and I both thank you in
advance for your continued interest and support for not only
the Sanctuary and its residents, but the Tigerhomes
Mission as well.
