Eurasian Lynx - Behaviour

Behaviour

Lynx preys largely on small to fairly large sized mammals and birds. Among the recorded prey items for the species are hares, rabbits, marmots, squirrels, dormice, other rodents, grouse, red foxes, wild boar, foxes, chamois, moose, roe deer, red deer, reindeer and other ungulates. Although taking on larger prey presents a risk to the animal, the bounty provided by killing them can outweigh the risks. The Eurasian lynx thus prefers fairly large ungulate prey, especially during winter when small prey is less abundant. They are the only Lynx species in which ungulates provide a great portion of their diet in relation to lagomorphs or rodents. Where common, roe deer appear to be the preferred prey species for the lynx. Even where roe deer are quite uncommon, as in Sweden, the deer are still quantitatively the favored prey species, though in summer smaller prey and occasional domestic sheep are eaten more regularly. In parts of Finland, introduced White-tailed deer are eaten mostly regularly. In some areas of Poland and Austria, red deer are the preferred prey and, in Switzerland, chamois may be locally favored. They will also feed on carrion when it is available. Adult lynx require 1.1 to 2 kilograms (2.4 to 4.4 lb) of meat per day, and may take several days to fully consume some of their larger prey.

The main method of hunting is stalking, sneaking and jumping on prey, although they are also ambush predators when conditions are suitable. In winter certain snow conditions make this harder and the animal may be forced to switch to larger prey. Eurasian lynx hunt using both vision and hearing, and often climb onto high rocks or fallen trees to scan the surrounding area. A very powerful predator, these lynxes have successfully killed adult deer weighing to at least 150 kg (330 lb).

The Eurasian lynx inhabits rugged forested country providing plenty of hideouts and stalking opportunities. Depending on the locality, this may include forest-steppe, boreal forest, and montane forest. In the more mountainous parts of their range, Eurasian lynx will descend into the lowlands in winter, following their prey, and avoiding the deepest snows. They tend to be less common where wolves are abundant, and wolves have been reported to attack and even eat lynx. In Russian forests, the most important predators of the Eurasian lynx are the gray wolf and the wolverine. Wolves kill and eat lynxes that fail to escape into trees. Lynx populations decrease when wolves appear in a region and are likely to take smaller prey where wolves are active. Wolverines are perhaps the most dogged of competitors for kills, often stealing lynx kills. Lynxes tend to actively avoid encounters with wolverines, but may sometimes fight them if defending kittens. Sometimes, Siberian tigers have also preyed on lynxes, as evidenced by examination of tiger stomach contents. Lynx compete for food with the predators described above, and also with the red fox, eagle owls, golden eagles, wild boar (which scavenge from lynx kills), and in the southern part of its range, the snow leopard and leopard as well.

Although they may hunt during the day when food is scarce, the Eurasian lynx is mainly nocturnal or crepuscular, and spends the day sleeping in dense thickets or other places of concealment. It lives solitarily as an adult.

The hunting area of Eurasian lynx can be anything from 20 to 450 km2 (8 to 174 sq mi), depending on the local availability of prey. Males tend to hunt over much larger areas than females, which tend to occupy exclusive, rather than overlapping, hunting ranges. The Eurasian lynx can travel up to 20 km (12 mi) during one night, although about half this distance is more typical. They patrol regularly throughout all parts of their hunting range, using scent marks to indicate their presence to other individuals. As with other cats, the scent marks may consist of faeces, urine, or scrape marks, with the former often being left in prominent locations along the boundary of the hunting territory.
