Brief Summary

Read full entry


Arizona Woodrats (or Packrats) typically have litters of two young, which can be born at any time of the year. Newborns weigh about 10 g. Their eyes open when they are not quite two weeks old, and they are weaned at three weeks. By the time they are three months old, females are mature. Adults have large, petal-like ears, relatively long, soft fur, and a moderately bushy tail, and usually molt once a year, in mid-summer. Arizona Woodrats have a somewhat limited distribution near tributaries of the Colorado River, bordered by the Grand Canyon in the north. The larger, White-throated Woodrat shares its range, forcing the Arizona Woodrat to occupy marginal locations.
