Rabbits how many babies per year

After a year, how many rabbits would you have? The formula used to derive the answer is called the Fibonacci sequence, and the rabbit problem is well-known and still used in math texts today.

The answer to the question posited by Fibonacci is rabbits would be produced in one year based on the scenario presented, Live Science reports. The math problem, though, is not based on the biology of rabbits. While Fibonacci's question does demonstrate some interesting principles about numbers and mathematical patterns, it isn't a true representation of how many rabbits one pair of rabbits can produce. As with many things in nature, many variables affect a cottontail rabbit's reproduction and life cycle, which makes it impossible to determine exactly how many rabbits one mating pair can become responsible for in their lifetime and beyond.

But when you consider that one female can birth three or four litters averaging five babies each, you can see that number gets big quickly when you take into account their offspring's offspring.

For that reason, an area's eastern cottontail rabbit population is nearly always on the verge of exploding, Pennsylvania State University reports. At any given time, the vast majority of the cottontail population is younger than 1 year old. If those rabbits live long enough to produce their own litters of offspring, the populations can quickly become very large very fast. The populations are kept in check by the rabbits' relatively short lifespan, which is typically less than three years.

Leave a minimum of 1 inch of cardboard or wood at the bottom of the doorway to deter newborns from wandering out of the box. Choose a corner of the box to put hay on which mama and the babies can sleep.

Avoid placing the hay where your rabbit eliminates. In encounters between the sexes, a female may at first face off in a threat posture and strike out at a male with her forepaws. As courtship proceeds, the two sexes may jump over one another, or one rabbit may leap into the air while the other darts beneath it. Breeding occurs from late March into August and September; during that span, a healthy female may produce several litters of young. Before giving birth, a mother cottontail makes a nest by digging a depression in the ground about 5 inches wide and 4 inches deep.

She lines the depression with grass and fur from her body, then adds a covering of twigs and leaves. Nests are built at night, in brush or among dense vegetation on the forest floor. After a roughly four-week gestation period, the mother gives birth in the nest. A typical litter has five or six young. Cottontails are born with their eyes shut. At intervals, the mother goes off to feed and then sneaks back to the nest to nurse her babies.
