Breeding and Life Span
The Gunnison’s prairie dog mating season begins in mid-March and lasts until mid-May. A female is able to reproduce at the age of one year. When food availability is scarce during the mating season, they may wait another year before breeding. Females engage in sexual intercourse for a single day during the mating season, and can mate with approximately five males, depending on the population density of their habitat. Gestation lasts, on average, 30 days. Females produce one litter per year of four to five pups.
Once the pups are born, the mother Gunnison’s prairie dog nurses the pups for about 30 to 40 days. During this time, the young pups remain safely in the nesting burrow located underground. Towards the end of lactation, the young are able to come out above ground; they must learn how to separate themselves from their mothers and survive on their own. As soon as the mother is done caring her young, she relocates herself to another burrow, leaving her now-independent young behind. Not too long after, they scatter to other vacant burrows. A high percentage of female Gunnison’s prairie dogs settle close to their birth territories for their entire lifetimes, whereas a significantly low percentage of the males stay close to their birth territories for longer than one year.
The life span of a Gunnison’s prairie dog is generally three to five years in the wild, but they can live up to eight years of age.
The population of the Gunnison’s prairie dog is declining drastically due to three major factors: shootings, plague cycles, and poisoning. Many concerned groups of people are requesting that the Gunnison’s Prairie Dog be listed under the federal Endangered Species Act.

Famous quotes containing the words breeding and, breeding, life and/or span:
“Good breeding and good nature do incline us rather to help and raise people up to ourselves, than to mortify and depress them, and, in truth, our own private interest concurs in it, as it is making ourselves so many friends, instead of so many enemies.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“The Fashionable World is grown free and easie; our Manners sit more loose upon us: Nothing is so modish as an agreeable Negligence. In a word, Good Breeding shows it self most, where to an ordinary Eye it appears the least.”
—Joseph Addison (1672–1719)
“Above all, we cannot afford not to live in the present. He is blessed over all mortals who loses no moment of the passing life in remembering the past.”
—Henry David Thoreau (1817–1862)
“What a large volume of adventures may be grasped within this little span of life by him who interests his heart in every thing, and who, having eyes to see, what time and chance are perpetually holding out to him as he journeyeth on his way, misses nothing he can fairly lay his hands on.”
—Laurence Sterne (1713–1768)
