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 environments, pronghorns rely heavily on their visual abilities to avoid predators, especially when population numbers are low. Mortality threats include predators, droughts, and lack of food; these risks predominantly affect young fawns, while adults also face mortality in drought-related situations.
