DALL SHEEP
DESCRIPTION
Dall Sheep, also known as Dall's Sheep, are a species of wild sheep found in the mountainous regions of North America. They are characterized by their white to cream-colored coats, which provide excellent camouflage against the rocky terrain. Males possess large, curved horns that can weigh up to 30 pounds, while females have smaller, less curved horns; both sexes exhibit a robust build adapted for their rugged habitat.
FUN FACTS
- Dall Sheep are named after the American naturalist William Healey Dall, who studied the species in the late 19th century
- Their ability to navigate steep and rocky terrains is remarkable; they can leap across gaps of up to 10 feet, making them well-adapted to their mountainous habitats.|Dall Sheep have a unique social structure, with females and young forming herds that can number in the dozens, while males often prefer solitude or small bachelor groups
- This social dynamic helps ensure the safety of the young while allowing males to compete for mates during the breeding season
