Physical Characteristics

Bison, also known as American buffalo, are large, shaggy mammals with a hump on their shoulders and a thick coat of fur. They have a massive head with short, curved horns and a beard-like chin mane. Adult bison can weigh up to 2,000 pounds and stand over six feet tall at the shoulder. On the other hand, Gaur, also known as Indian bison, are the largest species of wild cattle and have a muscular build with a distinctive ridge on their back. They have a dark brown coat with white stockings on their legs and can weigh up to 2,200 pounds.

Habitat

Bison are native to North America and can be found in grasslands, prairies, and forests. They once roamed in large herds across the Great Plains but are now primarily found in national parks and reserves. Bison are herbivores and graze on grasses, sedges, and other vegetation. Gaur, on the other hand, are native to South and Southeast Asia and inhabit dense forests and hilly areas. They are primarily found in India, Nepal, and Bhutan and prefer to live in areas with abundant water sources and dense vegetation for cover.

Social Behavior

Bison are social animals that live in herds, which can range in size from a few individuals to hundreds of animals. They have a hierarchical social structure with dominant bulls leading the herd and competing for mating rights. Bison communicate through vocalizations, body language, and scent marking. Gaur, on the other hand, are more solitary animals and are usually found in small groups or alone. They are known to be shy and elusive, preferring to avoid human contact whenever possible. Gaur communicate through vocalizations such as bellows and grunts.

Reproduction

Bison mate in the late summer and early fall, with calves being born in the spring after a gestation period of about nine months. Calves are able to stand and walk shortly after birth and are weaned at around six months old. Female bison typically give birth to a single calf, although twins can occur occasionally. Gaur also mate in the late summer and early fall, with calves being born after a gestation period of about nine months. Calves are cared for by their mothers and stay with them for several years before becoming independent.

Conservation Status

Bison were once on the brink of extinction due to overhunting and habitat loss, but conservation efforts have helped increase their numbers in recent years. They are currently classified as near threatened by the IUCN, with populations stable or increasing in North America. Gaur, on the other hand, are classified as vulnerable by the IUCN due to habitat loss, poaching, and human-wildlife conflict. Conservation efforts are underway to protect gaur populations and their habitats in countries where they are found.
