After a side discussion in Comments about bats, I’ve been searching the Bat Conservation International site for more information about how great bats are, how they help us, and how we can help them. Essentially, bats are pretty harmless to humans, but they eat a lot of bugs that make us sick, eat our food, or kill us (think West Nile Virus). So, bats are great! They eat what we want them to eat, and otherwise leave us alone.
Baby bats are called pups. Females have one pup per year – that’s a pretty low reproductive rate.
Bats live over 30 years, making them the longest living mammal for their size.
Bats and birds are not related.
One way to help bats is to build or put up a bat house to provide them shelter during the day so they can eat bugs at night. The best place to put a bat house is on a building or a pole, not on a tree.
In the United States, little brown bats often eat mosquitos and can catch up to 1,200 tiny insects in an hour. An average-sized colony of big brown bats can eat enough cucumber beetles to protect farmers from tens of millions of the beetle’s rootworm larva each summer. Large colonies of Mexican free-tailed bats eat hundreds of tons of moth pests weekly.
The biggest problem is human fear.
Another big problem for bats involves some of the things we do to the places where bats live. We spray a lot of chemicals, which are dangerous. Bugs are sprayed by the chemicals, and then the bats eat the chemical-coated bugs.
And, windmills are posing a problem for bats. As we strive to find renewable energy, we must remember to not harm other species in the process. (remember though, pollution from our gas-cars harm uncountable numbers of animals) The Bats and Wind Energy Consortium has joined together with energy innovators to find solutions. The Oregon Wind Turbine (below) is safe for birds and bats.
Recently, scientists have discovered White Nose Syndrome among bats in the North East. They don’t know the cause, but the mortality rate is 95%.
We should do what we can to help animals like bats. Without knowing, we depend on others for our survival, so it’s in our interest to keep them safe.
