Behavior
Wild yaks are the undisputed kings of the high-altitude tundra, possessing a stoic and hardy temperament suited for the brutal Himalayan climate. They are primarily social animals, with females and calves forming large, cohesive herds that can number in the hundreds. Adult males, by contrast, are often solitary or form small bachelor groups for most of the year, only joining the larger herds during the rutting season in autumn.
Unlike the docile domestic yak, the wild variety is extremely wary and suspicious of human activity. They have a highly refined sense of smell, which they use to detect predators and humans from great distances. When threatened, a herd will often flee into higher, more inaccessible terrain, but they are known to charge if they feel trapped or if a calf is in danger. Their movements are surprisingly graceful for their bulk, allowing them to navigate treacherous icy passes that would stop most other large mammals.

Camera Tips
Capturing a wild yak on camera is one of the ultimate challenges in wildlife photography due to their remote habitat and extreme wariness. Your best bet is to locate a natural 'highway'—look for well-worn trails through mountain passes or near high-altitude salt licks and glacial meltwater streams. Because these animals are so tall, mount your camera approximately 4 to 5 feet off the ground. Be sure to use an extremely secure mount, such as a heavy-duty security box or a rock-anchored bolt, as yaks are curious and may attempt to rub their massive bodies against your gear, which can easily crush standard plastic mounts.
Environmental conditions at these altitudes are brutal on electronics. You must use lithium batteries, as standard alkaline batteries will fail almost instantly in the sub-zero temperatures typical of yak territory. Consider a camera with a cellular uplink if you have signal, though in these remote areas, high-capacity SD cards are usually necessary. Set your camera to take a 'burst' of 3-5 photos per trigger; yaks move with a heavy, steady gait, and a single shot might only capture a portion of their massive bodies.
Scent control is critical when checking your cameras. Wild yaks can smell a human from over a kilometer away. Wear scent-blocking clothing and avoid visiting the camera site frequently—once every three months is ideal. To maximize your chances, use 'No-Glow' or 'Black Flash' infrared technology. Traditional red-glow IR can spook these animals in the dead of night, causing them to abandon the trail entirely. Look for areas with fresh 'pats' (dung) or disturbed earth where they have been foraging to ensure you are in an active zone.
