Wild boars live in groups called sounders. Sounders typically contain around 20 animals, but groups of over 50 have been seen. In a typical sounder there are two or three sows and their offspring; adult male Wild Boars are not part of the sounder outside of the autumnal breeding season and are usually found alone.
Birth, called farrowing, usually occurs in the spring. A litter will typically contain five piglets, however, up to 13 piglets in one litter have been known.
Wild boars are usually nocturnal, foraging from dusk until dawn but with resting periods during both night and day. This is because hunters are most active during the day. Wild boars eat almost anything they come across, including nuts, berries, carrion, roots, tubers, refuse, insects, small reptiles, even young deer and lambs.
The hair of the wild boar was often used for the production of the toothbrush until the invention of synthetic materials in the 1930s. The hair for the bristles usually came from the neck area of the wild boar.
