Living in open areas, pronghorns in general must rely on their eyesight to avoid predators, and with population numbers so low, the Sonoran pronghorn must avoid mortality at all costs. Sources of mortality come from predators, drought, and lack of feed; these sources usually affect fawns most often, and adult mortality also occurs in drought situations.
In open territories, pronghorns predominantly rely on their visual senses to avoid predators, particularly with low population numbers where survival is crucial. Mortality threats arise from predators, water shortages, and insufficient food; these risks primarily affect juvenile fawns most frequently, as well as adult mortality in arid conditions.
