How do Musk Oxen forage?
Musk Oxen move to areas with thinner snow to conserve energy while digging for plants.
Are Musk Oxen social?
Musk Oxen herd together, with winter herds ranging from 12 to 24 members and summer herds from 8 to 20. They have separate hierarchies for males and females and mark trails with scent from pre-orbital glands. Dominant oxen get the best food and defend their status by roaring, pawing, and rushing. Males show dominance by kicking and mock-mounting lesser males. When threatened, they form a defensive circle with bulls on the outside.
How fast can Musk Oxen move?
Musk Oxen can run up to 60 km per hour.
What are Musk Oxen mating rituals like?
Females mature at 3 years, males at 5. Mating season starts in July, with males clashing until one wins and forms a harem of about 6 females. The dominant male herds the females, kicking them to calm them before mounting. Pregnant females become aggressive and lead the herd's grazing. Pregnancy lasts about 8.5 months, with calves born from April to June. Calves move with the herd within hours and are weaned after 2 months.
How long do Musk Oxen live?
Musk Oxen live up to 20 years in the wild.
How many Musk Oxen are there today?
Estimates range from 80,000 to 125,000.
Do Musk Oxen have any predators?
The main predator is the Arctic Wolf, responsible for up to half of Musk Oxen deaths due to predation. Grizzly bears and polar bears also attack, mainly targeting the young and elderly.
