The Importance of Bats

For a very long time, I have been totally fascinated with bats.  We have had some great experiences with bat watching; even gone into an undeveloped Texas cave for guano and stayed to experience the emergence with no one around, standing there, waving our hands above our heads as they flew toward us, missing us every time.  It is awe inspiring.

Our experiences have been with Mexican Free-tailed bats Tadarida brasiliensis, the most common Texas bat.  Probably the species you watch from your porch on summer evenings.  They are here from about February and most begin to leave for Mexico now, in August.

The 20 million or so Mexican Free-tailed bats of Bracken Cave, the world’s largest known colony, eats a quarter of a million pounds or more of insects nightly, covering thousands of square miles.  These amazing creatures emerge each evening, climbing to more than 10,000 feet, and can catch tail winds that can drive them to speeds of over 60 miles per hour to distant feeding grounds.   It almost can’t be stated enough how bats are by far the most important controllers of night flying insects, even mosquitos.

To my surprise, I have learned that joining the Mexican Free-tailed bat in our skies are 8 additional species:  Big Brown bat Eptesicus fuscus, Silver-haired bat Lasionycteris noctivagans, Eastern Red bat Lasiurus borealis, Hoary bat Lasiurus cinereus, Northern yellow bat  Lasiurus intermedius, Seminole bat Lasiurus seminolus, Evening bat Nycticeius humeralis  and Tri-colored bat  Perimyotis subflavus.

Did you know:  Bats are highly intelligent and even trainable?  World-wide, there are over 1000 extremely diverse species?  Millions of bats are dying from White-nose Syndrome?  Some species hibernate rather than migrate?  Some species are vital pollinators?  Some feed on fruit or nectar?   Not all species roost in caves?  There are no blind bats?  They do not become entangled in people’s hair?  They pose less of a threat to human health than do household pets?

  1. We have actually seen more bats flying around our property this year. We hope they stay!!! Thanks for all the great articles, very informative.

    1. We like to sit on our front porch late in the evening right at dusk and watch the bats flying over our pond eating bugs. Nice to have them here at Oakridge. And we have a bat house to install in the next few days, too. Hope it helps attract more!
