Behavior of Koalas
The behavioral patterns of koalas can be described as lethargic and comatose. The typical day of a koala consists of 20% feeding time and 80% sleeping time. Less than 1% of their time is spent searching for a mate. During the summer season in which koalas breed, they become more active. In this season of breeding, a typical method for koalas to find a mate consists of wandering aimlessly until one is found.
Koalas have an exceptional "nose" for navigational skills. After being rehabilitated, koalas can return to their natural homes and have been know to travel several kilometers. If a koala is too far from its home range, or simply can't find its way back, it determines its new home based on the existing population of koalas in that area, as well as the source of food trees. Koalas prefer eucalyptus forests/woodlands and lowlands over dense forests and highlands.
In the breeding process, both male and female koalas have their own distinct grunting noises which are used to attract koalas of the opposite sex. The beginning of sexual maturity starts at age two and they usually establish their individual territories within the age of three or four. The gestation period for a koala is 34-36 days. Since the koala is a marsupial (from the Latin word marsupium, meaning "pouch") the female has a pouch in which there are two nipples where a newborn, or joey, will develop after it is born. A female usually has one young every one to two years. The joey is born at a length of two centimeters and weighs approximately half a gram. Once born, the newborn resembles a pink jellybean; it has no ears, it is totally blind, and is completely hairless. The joey travels to the pouch completely unaided and will stay there for several months. At twelve months, it is completely weaned and independent, but quite possibly might stay with its mother for a couple more years.
