Antionio Brack’s Oldfield Mouse

Common Name: Antionio Brack’s Oldfield Mouse
Scientific Name:

Habitat

Antionio Brack’s Oldfield Mouse primarily inhabits the arid regions of northeastern Mexico, particularly in the state of Coahuila. This species is often found in grasslands and shrublands, where it prefers sandy soils conducive to burrowing. The mouse thrives in areas with sparse vegetation, allowing for easy navigation and foraging.

Physical Characteristics

This mouse is relatively small, measuring approximately 11 to 15 centimeters in length, excluding its tail. Its fur exhibits a light brown to gray coloration, which aids in camouflage against the dry landscape. Notable features include large ears, a pointed snout, and a long, tufted tail. The coloration and size help distinguish it from other similar rodent species in the region.

Behavior

Antionio Brack’s Oldfield Mouse is primarily nocturnal, engaging in most of its foraging and social activities at night. It is highly social, often found in small groups. The species is well-known for its burrowing behavior, creating extensive tunnel systems that provide shelter from predators and harsh environmental conditions. Additionally, it exhibits territorial behavior, marking its territory with scent to ward off intruders.

Diet

This species is omnivorous, with a diet that primarily consists of seeds, grains, and insects. Antionio Brack’s Oldfield Mouse is particularly adept at feeding on the seeds of various grasses and annual plants found in its habitat. The mouse’s foraging behavior enables it to adapt to seasonal changes in food availability.

Reproduction

The breeding season for Antionio Brack’s Oldfield Mouse typically occurs from spring to early fall, with females capable of producing multiple litters each year. Each litter usually consists of three to six offspring, which are weaned after about three weeks. Maternal care is extensive, with females actively nurturing their young until they are ready to fend for themselves.

Conservation Status

Currently, Antionio Brack’s Oldfield Mouse is classified as endangered due to habitat loss and environmental changes. Urbanization and agricultural expansion threaten its natural habitat, making conservation efforts crucial for the survival of this unique rodent.

Interesting Facts

One fascinating fact about Antionio Brack’s Oldfield Mouse is that it has developed particular adaptations for survival in arid environments, such as efficient water retention capabilities. This makes it an interesting subject for ecological studies.

Role in Ecosystem

Antionio Brack’s Oldfield Mouse plays a significant role in its ecosystem as both a seed disperser and a prey species. By consuming seeds and later excreting them in different locations, the mouse contributes to plant propagation. Additionally, it serves as an important food source for various predators, including birds of prey and snakes, supporting the biodiversity of its habitat.
