Reproduction
Female eastern fox squirrels come into estrus in mid-December or early January then again in June. they normally produce two litters a year, however, yearling females may only produce one. Females become sexually mature at 10 to 11 months of age and usually produce their first litter when they are a year old.
Gestation occurs over a period of 44 to 45 days. Earliest litters appear in late January; most births occur in mid-March and July. The average litter size is three, but can vary according to season and food conditions.
Tree squirrels develop slowly compared to other rodents. At birth, the young are blind, without fur and helpless. Eyes open at 4 to 5 weeks of age and ears open at 6 weeks. Eastern fox squirrels are weaned between 8 and 10 weeks but may not be self-supporting until 12 weeks. Juveniles usually disperse in September or October, but may den either together or with their mother during their first winter.

Famous quotes containing the word reproduction:
“Were I called on to define, very briefly, the term Art, I should call it “the reproduction of what the Senses perceive in Nature through the veil of the soul.” The mere imitation, however accurate, of what is in Nature, entitles no man to the sacred name of “Artist.””
—Edgar Allan Poe (1809–1845)
“It is so characteristic, that just when the mechanics of reproduction are so vastly improved, there are fewer and fewer people who know how the music should be played.”
—Ludwig Wittgenstein (1889–1951)
“The chief function of the city is to convert power into form, energy into culture, dead matter into the living symbols of art, biological reproduction into social creativity.”
—Lewis Mumford (1895–1990)
