They exhibit territorial behavior, marking their territories with scent markings and engaging in displays of strength to ward off rivals. The males also engage in elaborate courtship rituals, including chasing and posturing to attract females.

Sexual maturity in pronghorns is reached at around one year of age for both males and females. However, males may not have access to mates until they establish their dominance later in life.

Females become receptive during the rut, and after mating, they undergo a gestation period of about 250 to 270 days. In late spring or early summer, pronghorn does give birth to their young, referred to as fawns.

Typically, a female pronghorn gives birth to one or two fawns at a time. These fawns are precocial, which means they can stand and walk within hours of being born.

Unlike other ungulates, such as deer, fawns are odorless at birth, providing them with added protection from predators. For the first two to three weeks of their lives, fawns remain hidden in vegetation during the day, while the mother feeds nearby.

This behavior helps to protect them from predators. The mother returns regularly to nurse her young, who mainly rely on milk for their sustenance during this time.

After a few weeks, the fawns start to venture out more, gradually joining their mother in foraging trips. They begin to sample solid foods and transition to a diet similar to that of adult pronghorns.

This period, known as weaning, continues for a few months until the fawns can survive entirely on their own. Pronghorns have relatively long lifespans compared to other ungulates.

In the wild, they can live between 10 and 15 years, with some individuals reaching the age of 20. The exact lifespan of pronghorns can vary due to factors such as predation, disease, and availability of resources.
