Bats and God’s Universe

Bats at Congress Avenue Bridge, Austin, TexasWe’ve all heard the saying, “God moves in a mysterious way.” This is from an old hymn written in 1773 by William Cowper. A well-known author, pastor and theologian from the last century, J. Vernon McGee, put it in a different way, “This is God’s universe and he does things his way. Now, you may have a better way of doing things, but you don’t have a universe.”

Keep that in mind for a moment and let’s look at bats. I have become fascinated by these little creatures. I have photographed them just a few times, but I hope to do more.

Bats are not flying mice or rodents. They are their own group called chiropterans. Bats are hugely varied in different types and species. In fact, almost a quarter of all mammals are bats.

As a group, bats eat a huge range of food. Most people know they eat insects, and a large portion of bats do. But different species eat fruit, nectar, and all kinds of animals from frogs to fish to even scorpions and much more. But even the insect eaters specialize in different ways of eating. Some catch insects on the fly, which we all know. But some work from perches to catch larger insects. Others flutter through trees and along the ground and pick off their prey from branches and rocks. As you can probably guess, this means bats come in all sizes, from the tiny bumblebee bat of SE Asia that is a little over an inch long and weighs less than an ounce to the big flying fox fruit bats of Australia that have a wingspan of nearly six feet and weigh over three pounds.

Even the bats that catch insects are different. Some fly high over vegetation to catch insects there, others work dense woods to find insects there, and still others change the times at night that they fly in order to catch certain insects.

Bats fly differently, too, which makes sense when you think about their variety of size and food. Some fly slowly and do a lot of fluttering. Some are speedy fliers who zoom through the air. Others have the ability to hover and fly through the tight spaces of a tree while chasing insects. Each bat flying style means that bats have different sizes of wings in relation to their bodies, from long and tapered to short and rounded.

Bats at Congress Avenue Bridge, Austin, TexasWe all know about bats in caves, but that is not all bats, and some bats only use caves to hibernate. Bats like the Mexican freetailed bat will use bridges, which is what is seen in the photos here from Austin, Texas. Many bats roost in trees – fruit bats of Africa will fill a large tree as they roost there. Different species of bats in North America will use old woodpecker holes, openings in trees from dead branches, spaces under loose bark, and even hang from branches looking like a bunch of dead leaves. There are bats in the tropics that will find insect holes in bamboo and roost inside the bamboo. There are even bats there that will chew the central stem of a palm large leave so that it folds over like a tent and roost there.

Some thoughts about their amazing echolocation skills: Bats put out high pitched sounds that we cannot hear. This bounces off prey like a fish finder bounces off fish hidden in waters below. With these echolocation skills, some bats can discern things as small as a human hair. This does not mean bats cannot see, however. Bats can see just fine, and some have extremely good eyesight to enable them to find specialized prey. And they do not get into people’s hair!

To me, all of this and more is absolutely amazing. I really had no idea, and I think that is true of most people. After all, bats are mostly out at night and spend much of the day hidden away.

Sometimes I have heard people say that they do not understand why a certain animal exists, or maybe worse, they consider life they don’t know to be unimportant. Nowhere in the Bible does it say that God made life only FOR man. Genesis talks about creation as an act of God apart from man and that God saw it was all good.

This is indeed God’s world and we share it with all of his creations, including bats. Just knowing what amazing life God has created and allowed, apart from man, says a lot about how important it all is, and why it is all worth caring for.
