What Can We Do to conserve bat habitat?|
What are the dangers to bat population?
Map shows US-area where Mexican free-tailed bats = Brazilian free-tailed bats have been watched.|
Also live in the warmer parts of the Americas
Populations have declined:
Decrease in habitat + damage to roosts + Consumption of pesticides
Mexican free-tailed bat Latin Tadarida brasiliensis = Brazilian free-tailed bat is native to the Americas.|
Fossils show that bats have lived for over 50 million years on Earth. About 950 varieties are counted.
Bats are very important in the balance of Nature. They are good pollinators, and they eat a lot of insects - giving many plants a chance to thrive.
Many people are asking:
"What will be my future when there is no bat left?"

|Look how small Tadarida Brasiliensis is A really small flying mammal!|
Small with big ears to hear every sound!
Bats use echolocation! They send out a high pitch sound
The sound is reflected by an object and in the brain of the bat an image forms. These image shows the bat what is in front of it:
A tree trunk or something to eat ...
So bats fly around at night, sometimes over 40 miles and eat mainly insects
That's how we can see them - In flight they look quite impressive!
At dawn the bats fly out of their caves and start to look for food:
Mainly moths, beetles, dragonflies, flies, true bugs, wasps, bees, ants
Brazilian free-tailed bats eat large numbers of insects nightly, helping to reduce agricultural pests or disease carrying bugs.
There is a very positive economic impact on agriculture, and gardening.
Hawks and owls are hunting for bats
Texas has with the Bracken Cave the largest bat colony with over 20 mill. Mexican free-tailed bats, located close to San Antonio
They have to fly ~1,000 miles from Mexico to this cave.
After arriving in the cave, the migrant mothers give birth to one pup.
At dawn you can see Mexican free-tailed bats dipping into the pond of Bear Springs Blossom Nature Preserve
Bats need water as all mammals do
At our Bear Springs Blossom Nature Preserve Mexican free-tailed bats have to navigate well with their echolocation system to fly around our native Texas "cedar" = juniperus trees
around our oak and cherry trees!
