As the fastest land animals in North America, pronghorns (Antilocapra americana) can run at speeds of up to 60 mph. The zippy ungulates resemble deer, but with longer legs and snouts. Males and females both have horns, but those on males tend to be significantly longer than the females’ short nubs. The herbivores range across Arizona, but southeastern and northern grasslands are where you’ll find large herds like the one pictured here, near Sonoita. Interestingly, pronghorns seldom drink water, absorbing most of what they need from the plants they consume.
