They are vilified as bloodsucking, evil creatures that create mayhem and leave destruction in their wake. No, we’re not talking about executives proliferating Ponzi schemes. We’re talking about bats. Bats were once widely maligned, misunderstood, and needlessly feared. Thanks to intense education efforts, more people understand that these beautiful, mysterious creatures are vital to their ecosystems. Bats devour billions of pesky mosquitoes and other annoying insects every night while others serve as pollinators for plants.
They are the only true flying mammals. And they are extremely good at it. Unlike birds, bats can move each wing independently of the other. They can change the curvature of their wings just by bending or unbending their fingers. All this allows for precise flight control. A bat flying at 40 miles per hour can literally turn on a dime and make a right-angle turn in a distance little more than the length of its body.
If that weren’t intriguing enough, bats have big hearts! The metabolic cost of flight is high, and it takes a super athletic heart to supply blood and oxygen to flight muscles. When "resting", bats have a heart rate of 450 beats per minute. When they fly, that approaches 20 beats per second or 1200 beats per minute. Their heart rate returns to resting rate within a second of landing. That’s amazing! Olympians take ten or more minutes to come to their resting heart rate after strenuous exertion.
Now that bats are increasingly seen as fascinating creatures to be valued and viewed, there is increased demand by the public for information on where and how they can go to view bats. Great bat-viewing sites are being recognized and developed everywhere. To help locate these sites, Bat Conservation International published a book "The Vacationer's Guide to Bat Watching". Unfortunately, no sites in Colorado are yet listed in the book. Not to worry. Eighteen species of bats live in Colorado. They can be found in every part of the state, from mountains and shrub lands to urban neighborhoods.
