2002, National Research Council, Ecological Dynamics on Yellowstone's Northern Range, unnumbered page,If historical records are accurate, the current population of about 250 pronghorn in the northern range is less than 15% of that in the early 1900s (YNP 1997) (Figure 4–7).
2009, John A. Byers, Built for Speed: A Year in the Life of Pronghorn, page 6,When a pronghorn breaks into an easy, rocking canter (a 30 miles per hour pace that it can keep up indefinitely), the humerus swings back and forth over just a few inches with each stride. Only when a pronghorn stretches into a gallop does the humerus appear to be swinging freely, and then the hoof travels several yards with each stride.
