Quick Answer
To distinguish between male and female pronghorn in Wyoming, look for a more slender build and a lighter-colored coat on females. Males typically have a darker coat with a more pronounced white rump patch. The horns of males are also larger and more pronounced.
Physical Characteristics
When observing pronghorn in Wyoming, note that females tend to be slightly smaller than males, weighing approximately 80-100 pounds, while males typically weigh 100-130 pounds. Males also have a darker coat color, often with a more pronounced reddish-brown hue, particularly on the throat and shoulders. In contrast, females have a lighter coat color, often with a more grayish-brown hue.
Horns and Antlers
Males have more pronounced and larger horns than females, often with a lyre-shaped curve. The horns of males can grow up to 10 inches long and weigh up to 2 pounds, while those of females are typically smaller, measuring around 5-6 inches long. The horns of males also have a more prominent brow tine, which can be a distinguishing feature.
Behavior and Habitat
Males tend to be more aggressive and territorial than females, which can lead to distinctive behaviors such as bugling and displaying their horns during the mating season. Females, on the other hand, tend to be more solitary and often inhabit areas with more cover and vegetation, such as sagebrush and grasslands. When observing pronghorn in Wyoming, consider the time of year and the behavior of the animals to help distinguish between males and females.
