Common Name: Central Andes Oldfield Mouse

Scientific Name: Abrothrix andina

Habitat:

The Central Andes Oldfield Mouse is primarily found in the high-altitude grasslands and shrublands of the Central Andes region, spanning parts of Argentina, Bolivia, and Peru. These environments are characterized by rugged terrains, and rocky outcrops, making them ideal for this species.

Physical Characteristics:

The Central Andes Oldfield Mouse typically measures between 20 to 30 cm in length, including a long, slender tail. Its fur is generally light brown to gray, providing excellent camouflage against the rocky landscape. Notable features include large, rounded ears and sharp incisors, adapted for its herbivorous diet.

Behavior:

This species exhibits nocturnal behavior, primarily foraging at night to avoid daytime predators. Central Andes Oldfield Mice are known for their social structures, often found in small groups, and exhibit varied communication tactics including chirps and squeaks to alert others of danger.

Diet:

The diet of the Central Andes Oldfield Mouse consists mainly of seeds, fruits, and green vegetation. These mice play a crucial role in their ecosystem as seed dispersers, facilitating reproduction for various plant species. During harsh winters, they may access stored food within their burrows.

Reproduction:

Breeding typically occurs from spring to early summer, with females giving birth to litters of 3 to 5 offspring. After a gestation period of about 21 to 25 days, the young are weaned at around 3 weeks and are capable of independent foraging shortly thereafter.

Conservation Status:

Currently, the Central Andes Oldfield Mouse is classified as vulnerable due to habitat loss from agriculture and urban development. Conservation efforts are critical to preserving this unique species and its habitat.

Interesting Facts:

An intriguing fact about the Central Andes Oldfield Mouse is its ability to survive in extreme conditions present at high altitudes, where temperatures can drop significantly. These adaptations make them unique among rodents in similar alpine ecosystems.

Role in Ecosystem:

The Central Andes Oldfield Mouse plays a vital role in maintaining ecological balance within its habitat. As both prey for larger predators and a mechanism for seed dispersal, this species is integral to preserving biodiversity in the challenging environments of the Andes.
