Behavior
It is nocturnal and omnivorous, with a preference for grains and fruit. Compared to the brown rat, it is a poor swimmer, but more agile and a better climber, tending even to flee upwards. In a suitable environment it will breed throughout the year, with a female producing three to six litters of up to ten young. Females may regulate their production of offspring during times when food is scarce, producing as few as only one litter a year. R. rattus lives for about 2–3 years. Social groups of up to sixty can be formed.

Famous quotes containing the word behavior:
“No one is without Christianity, if we agree on what we mean by that word. It is every individual’s individual code of behavior by means of which he makes himself a better human being than his nature wants to be, if he followed his nature only. Whatever its symbol—cross or crescent or whatever—that symbol is man’s reminder of his duty inside the human race.”
—William Faulkner (1897–1962)
“I don’t see much future for the Americans.... Everything about the behavior of American society reveals that it’s half Judaized, and the other half negrified. How can one expect a State like that to hold together?”
—Adolf Hitler (1889–1945)
“I like to think of my behavior in the sixties as a “learning experience.” Then again, I like to think of anything stupid I’ve done as a “learning experience.” It makes me feel less stupid.”
—P.J. (Patrick Jake)
