Common Name: Inca Oldfield Mouse

Scientific Name: Abrothrix boliviensis

Habitat:

The Inca Oldfield Mouse is primarily found in the grasslands and shrublands of the Andean region, specifically in countries such as Peru and Bolivia. These rodents thrive in high-altitude environments, often inhabiting regions up to 4,000 meters above sea level. Their preferred habitat includes areas with abundant vegetation, which provides shelter and food sources.

Physical Characteristics:

This species of mouse typically measures about 15 to 20 cm in total length, including its tail. The Inca Oldfield Mouse is characterized by its soft, dense fur which ranges in color from light brown to grayish-brown, providing effective camouflage against the rocky terrain. Its ears are relatively large, aiding in acute hearing, while its long, thin tail helps with balance. Notably, they possess strong, clawed feet that enable them to navigate rocky surfaces seamlessly.

Behavior:

The Inca Oldfield Mouse is primarily nocturnal, showcasing a range of interesting behaviors suited for survival in its harsh habitat. They are known for their burrowing abilities, creating intricate tunnel systems to avoid predators and harsh weather conditions. Additionally, these mice are social creatures and often live in small groups, which aids in foraging and protection against threats.

Diet:

The diet of the Inca Oldfield Mouse consists mainly of seeds, roots, and various plant materials. They play an important role in seed dispersal, which contributes to the health of their ecosystem. Their foraging habits are opportunistic, often changing with the season based on food availability. This adaptability helps them survive in the challenging Andean environment.

Reproduction:

Inca Oldfield Mice typically breed throughout the year, although peaks in reproduction may occur during the wet season when food is most abundant. Females usually give birth to litters of 3 to 5 young after a gestation period of approximately 27 days. The young are born blind and helpless, relying on their mother for nutrition and protection until they reach maturity.

Conservation Status:

The conservation status of the Inca Oldfield Mouse is currently listed as Least Concern by the IUCN, although habitat loss due to agriculture and development poses potential risks. Ongoing monitoring is essential to ensure the sustainability of populations in their native range.

Interesting Facts:

One fascinating aspect of the Inca Oldfield Mouse is its ability to survive in extreme altitudes where few other mammals can thrive. Additionally, they are known to exhibit behaviors such as grooming and social bonding, which are critical for their survival in the wild.

Role in Ecosystem:

The Inca Oldfield Mouse plays a vital role in the Andean ecosystem. As herbivores, they contribute to the regulation of plant growth and serve as prey for higher trophic levels, such as birds of prey and larger mammals. Their activities help facilitate seed dispersal, promoting biodiversity and the health of their natural habitats.
