Golden Mouse (Ochrotomys nuttalli) lives in eastern woodlands across Southeastern North America. It feeds on seeds and insects. Its conservation status is Least Concern.
Fascinating facts about the Golden Mouse
- The golden mouse builds nests that are typically about 100 to 200 mm across and usually have a single opening, but exceptional nests have been recorded with as many as 57 entrances. Inside, the mouse lines the chamber with soft fibres such as milkweed, cotton, feathers or fur, surrounded by a woven layer of leaves, grass and bark.
- Golden mice are notably gregarious and do not defend strict territories, so the home ranges of several individuals often overlap. Observations have shown up to eight individuals sharing a single nest, whether they are related or not, forming groups that can include mothers and their young. Scientists have suggested that such communal living conserves energy, especially in winter when the low basal metabolic rate and high conductance make group warmth advantageous.
- In captivity a female golden mouse can produce an extraordinary number of offspring, with records of up to 17 litters in an 18-month span. The short gestation of just 25 to 30 days means several litters can be raised each year, and the size of each litter varies from one to four young, often larger in the fall. This rapid breeding cycle enables the species to maintain its secure population across its wide southeastern range.
- The golden mouse's tail measures between 50 and 97 mm, generally the same length as its body, which ranges from 50 to 115 mm. This prehensile tail is used for balance while the mouse moves through trees and shrubs.
- Golden mice will take over abandoned bird nests, reshaping them into suitable homes rather than constructing a new structure from scratch. This behaviour lets them exploit ready-made shelters high in the canopy, saving the effort of gathering materials. When a suitable nest is not available they build their own, creating a nest 100 to 200 mm across from locally sourced elements.
