Woodchucks do, however, have the continuously growing incisors characteristic of rodents. There have been several documented cases of pebbles being lodged between the incisors and causing off-lining to occur. If starvation does not cause death first, the teeth will continue to grow and curve around up into the skull, killing the woodchuck. DIET Woodchucks are primarily herbivorous, with a diet consisting of green vegetation. They can consume over 5 kg of green plants a day, such as alfalfa, clover, grasses, herbs, apples, peas, corn, other fruits, and the bark of trees.
Females mate only once, but males are promiscuous.
Younger females tend to mate later than older females. The gestation period is 31 or 32 days, with one litter born each year. In Ohio, births occur the first two weeks of April. The young are naked and blind, and weigh around 25 grams. They begin leaving the dens to forage six weeks after birth and are weaned two weeks later.
