Burneo’s Oldfield Mouse

Common Name: Burneo’s Oldfield Mouse
Scientific Name:

Habitat

Burneo’s Oldfield Mouse is primarily found in the subtropical and temperate regions of South America, particularly in the grasslands and savanna ecosystems. Their range includes areas in central Brazil and parts of Paraguay. This species thrives in open habitats such as fields, meadows, and disturbed lands, where vegetation provides ample shelter and foraging opportunities.

Physical Characteristics

Burneo’s Oldfield Mouse is characterized by its small size, typically measuring around 12 to 16 centimeters in length, not including its long, tufted tail, which can add another 10 to 12 centimeters. The fur is generally a soft, gray-brown color, allowing them to blend seamlessly into their natural surroundings. Distinctive features include large, expressive eyes and prominent ears, which assist in their survival by enhancing their hearing capabilities.

Behavior

This species is primarily nocturnal, showcasing increased activity during the night. They are known for their burrowing behavior, creating elaborate tunnel systems that serve as both homes and protection from predators. Burneo’s Oldfield Mouse exhibits social behaviors, often living in small groups, which facilitates collective foraging and increased vigilance against threats. These mice are also known to engage in playful interactions, a behavior that has intrigued researchers.

Diet

Burneo’s Oldfield Mouse primarily feeds on seeds, fruits, and grasses. They are granivorous, meaning they primarily consume grains, which are abundant in their habitats. This diet allows them to thrive in grassland ecosystems. Additionally, they may occasionally consume insects and other small invertebrates, contributing to their diverse feeding habits.

Reproduction

The breeding season for Burneo’s Oldfield Mouse typically occurs during the wet season, from October to March. Females give birth to litters averaging 3 to 5 offspring after a gestation period of about 21 days. The young are weaned after 3 to 4 weeks and exhibit rapid growth, becoming sexually mature by the time they are approximately 2 months old. Parental care is shared among group members, enhancing survival rates among the young.

Conservation Status

Currently, Burneo’s Oldfield Mouse is listed as vulnerable due to habitat loss and degradation resulting from agricultural expansion and urban development. Conservation efforts are essential to ensure the survival of this unique species and its habitat.

Interesting Facts

Burneo’s Oldfield Mouse is known for its unique vocalizations, which include chirps and squeaks used for communication within social groups. Surprisingly, studies have also suggested that they can recognize their relatives, which is uncommon in many rodent species.

Role in Ecosystem

As a seed disperser, Burneo’s Oldfield Mouse plays a vital role in its ecosystem by aiding in plant propagation and promoting plant diversity. They serve as prey for various predators, including birds of prey and snakes, making them an integral part of the food web within their habitat.
