Lynxes are solitary, and only form breeding pairs for short periods. They are territorial and very quiet, moving mainly at night, in the early morning and late evening, so they are not easy to see. Although they can colonize a wide range of habitats, they prefer densely wooded, well-canopied forests with plenty of undergrowth where they can hunt and make their dens. In Romania, there are thought to be one to three adults per 100km2, although larger populations of up to five per 100km2 have been reported elsewhere in Eastern Europe.
The bear’s diet is omnivorous, as its teeth plainly show. Brown bears have strong canines for defence, and for killing and ripping their prey. Their post-carnassials and premolars have large areas of contact, helping them to grind up plants and invertebrates. In summer and early autumn, bears forage for mushrooms, and fruits, such as raspberries, blackberries, blueberries, apples, plums and pears. In late autumn and during the winter, bears eat acorns and beechnuts. Insects such as Hymenoptera (ants, bees and wasps) can be an important source of protein. But bears do best on a diet of fresh meat or carrion. Bears can vary a lot in size. If you measure a bear on all fours, from its feet to the highest point of the shoulder, a mature bear can range in height from 90 to 150 cm. Lengthwise, from its nose to the top of its tail, a female can reach betweeen 150 and 165 cm, and a male from 170 and 200 cm. The average weight for Romanian bears is between 100-200kg for females, whereas males can tip the scales at between 140-320 kg. Not to be trifled with!
