🐭 Little Indian Field Mouse (Mus booduga) – The Tiny Tiller of Indian Fields

The Little Indian Field Mouse (Mus booduga) is a small, yet significant rodent species widely distributed across the Indian subcontinent. Though modest in size, it plays a crucial role in agriculture, soil health, and as prey in the food web. It is one of the most commonly seen small mammals in rural landscapes, especially paddy fields and crop lands.

Let’s delve into its taxonomy, morphology, behavior, habitat, and its ecological role — especially within regions like the Sundarbans.

🌾 Habitat & Distribution

• Found widely across India, Sri Lanka, Nepal, and other parts of South Asia.

• Commonly inhabits cultivated lands, fallow fields, forest edges, grasslands, and rural settlements.

• Burrows in moist soil, often creating shallow tunnels and chambers near crop roots.

🌟 Special Features & Behavior

🔹 Agricultural Associations

• Most frequently found in paddy fields, millet farms, and sugarcane plantations.

• Known to feed on grains, seeds, shoots, and sometimes insects, leading to their classification as minor agricultural pests.

🔹 Burrowing & Nesting

• Builds small burrows with separate chambers for nesting and food storage.

• Mice often line their nests with grass, leaves, and soft material.

🔹 Breeding Habits

• Highly prolific breeders, especially during monsoon and post-harvest seasons.

• A female can give birth to 4–8 pups in a litter, and several litters in a year.

🔹 Predation Role

• Preyed upon by a wide variety of snakes, owls, jungle cats, and fishing cats, making them crucial in maintaining the ecological balance of agro-ecosystems.

🌿 Presence in the Sundarbans

Although more commonly associated with agricultural regions, the Little Indian Field Mouse is also found on the fringes of the Sundarbans, particularly in rural fields and buffer zones of the mangrove region.

🌱 Role in the Sundarbans Landscape:

• Serves as prey for raptors like owls, mangrove snakes, and the Fishing Cat, contributing to the food chain in this ecosystem.

• Their burrowing can aerate the soil, promoting healthy root systems in buffer vegetation around human settlements.

🚨 Conservation Status

• IUCN Red List: Least Concern

• Due to their abundance and adaptability, Mus booduga faces no significant conservation threats at present.

• However, heavy use of pesticides and rodenticides in farmlands poses localized threats.

While the Little Indian Field Mouse might appear insignificant, it’s a keystone species in rural and semi-wild ecosystems like those on the edges of the Sundarbans. Understanding its role can help in fostering more eco-friendly agricultural practices and biodiversity-sensitive land management.
