Prairie Wildlife

Drawings of pronghorn antelope from my shrub grassland sketchbook. Pronghorn are interesting animals to observe and draw - beautiful markings, strong horns, and big brown eyes. They are thought to have evolved to outrun the now extinct American cheetah. As such they are the fastest mammal in North America, running at speeds of up to 40-60 mph! To enable them to run this fast, their heart, lungs, and trachea are several times larger than other similar sized ungulates and they have high levels of hemoglobin in their blood. While their long legs appear lightweight and delicate, they are made with strong bones. With the largest eyes of any North American ungulate, they can see a 300 degree arc without moving their head, allowing them to detect predators at great distances.
