North America’s fastest mammal, the pronghorn can accelerate explosively from standing to a top speed of 60 miles per hour—but it can also cruise at 45 mph for many miles. What accounts for the speed of this extraordinary animal? And what is it like to be a field biologist dedicating 20 years to studying this species? Byers answers these questions.
