Statistics

Head and body length: 18cm, Weight: 200-400g.

Physical Description

Brown rats have coarse brown (occasionally black) fur, with a pale underside. They have a long tail, which is sparsely haired.

Distribution

Although originally native to east Asia and Japan, brown rats are now distributed world-wide. They are found all over Britain except for exposed mountain regions and some small offshore islands.

Habitat

Brown rats are highly adaptable and can be found in a variety of habitats, typically near human habituation.

Diet

Brown rats are omnivorous but prefer starch and protein-rich foods, such as cereals. Their diet includes meat, fish, vegetables, weeds, earthworms, crustaceans, nuts and fruit. They sometimes cache food to return to later.

Behaviour

They are typically nocturnal, although they will sometimes forage for food during the day.

They live in loose colonies, made up of aggregations of clans - usually consisting of a mated pair, or a male and a harem of females. Clans will defend their territory from other rats, and there is a dominance hierarchy whereby the biggest rats are dominant over their smaller counterparts.

Home ranges are generally 50 metres in diameter. In areas of high population, fights will often break out, involving a vigorous scuffle leading to the loser being chased off and bitten on the rump.

Brown rats swim well and are sometimes mistaken for water voles. Rats have well-developed senses of hearing and smell.

Reproduction

Brown rats breed throughout the year and can produce five litters a year. Females give birth to an average of eight young, after a gestation of 22-24 days. These are weaned after 3-4 weeks.
