Niceforo Maria’s Oldfield Mouse

Common Name: Niceforo Maria’s Oldfield Mouse
Scientific Name: Oryzomys nicobaricus

Habitat

The Niceforo Maria’s Oldfield Mouse is primarily found in the temperate forests of Colombia and Panama. This species thrives in moist habitats including lowland deciduous forests and areas rich in vegetation. As an adept climber, it favors regions with dense underbrush and abundant ground cover, providing essential shelter and foraging opportunities.

Physical Characteristics

This small rodent typically measures between 8 to 10 inches in length, including its long, slender tail. The fur is predominantly a soft brown color with lighter underparts. A distinctive characteristic is the large, rounded ears and prominent eyes, which enhance its nocturnal activity. Notably, its feet are slightly larger in proportion to its body, assisting in swift movement across varied terrains.

Behavior

Niceforo Maria’s Oldfield Mouse exhibits fascinating behaviors, particularly its nocturnal foraging habits. These mice are known for their agility and exploration, often jumping between branches and using their keen sense of smell to locate food. They are also social creatures, sometimes forming loose colonies within their habitat. Their vocalizations and playful interactions enhance their social structure.

Diet

The diet of Niceforo Maria’s Oldfield Mouse consists mainly of seeds, fruits, and small invertebrates. This species is particularly attracted to nuts and berries, which are abundant in its natural habitat. Its foraging behavior plays a vital role in seed dispersal, contributing to the growth of various plant species in its environment.

Reproduction

Reproduction in Niceforo Maria’s Oldfield Mouse occurs throughout the year, with peak breeding seasons during the wetter months. Females typically give birth to 2 to 6 offspring per litter, which are altricial at birth, meaning they are born hairless and dependent on their mother. Maternal care is observed as vital during the formative weeks, with young mice becoming independent at approximately 16 to 21 days old.

Conservation Status

Currently classified as endangered by the International Union for Conservation of Nature (IUCN), the Niceforo Maria’s Oldfield Mouse faces habitat loss due to deforestation and agricultural expansion. Conservation efforts are critical to preserving its remaining habitats and ensuring the survival of this unique species.

Interesting Facts

Notably, the Niceforo Maria’s Oldfield Mouse is a lesser-known species that was only recently identified, which adds to the intrigue of its study among biologists. Additionally, this rodent is named after the eminent Colombian biologist Niceforo Maria, reflecting the importance of local contributions to biodiversity research.

Role in Ecosystem

As a crucial member of its ecosystem, Niceforo Maria’s Oldfield Mouse plays a significant role in nutrient cycling and seed dispersal, impacting forest health and growth. Its presence supports a diverse array of predators, including birds and small mammals, thereby maintaining ecological balance within its habitat.
