White-footed Vole: An In-Depth Species Description

Common Name: White-footed Vole
Scientific Name: Microtus pennsylvanicus

Habitat

The White-footed Vole is primarily found across North America, particularly in the northeastern United States and parts of Canada. This small mammal thrives in moist environments such as meadows, marshes, and the edges of wetlands. They favor areas with dense vegetation and rich soil, enabling them to burrow and find food effectively.

Physical Characteristics

Measuring about 4 to 6 inches in length, the White-footed Vole is a small rodent known for its distinctive pale underbelly and white feet. Its fur is typically a shade of brown or gray with a slightly darker dorsal region. Their small ears and short tails, which are less than half the body length, contribute to their unique appearance, making them easily identifiable among other voles.

Behavior

White-footed Voles are primarily nocturnal, engaging in most of their foraging activities during the night. They are known for their burrowing habits, where they create extensive tunnel systems that serve as both shelters and pathways to food sources. During the day, these voles reside in hidden nests made of grass and leaves, which offer protection from predators. Their social behavior can vary, with some individuals being solitary while others may form small family groups.

Diet

The diet of the White-footed Vole predominantly consists of herbaceous plants, seeds, roots, and occasionally bark. They are known to feed on grasses, clover, and various weeds. This species plays an important role in the ecosystem as a herbivore, contributing to the control of plant populations and serving as prey for various predators, including owls and foxes.

Reproduction

White-footed Voles typically breed from spring through early fall. After a gestation period of about 21 days, females give birth to litters ranging from three to seven offspring. The young are altricial at birth, meaning they are born hairless and blind, and they gradually develop over the next few weeks. Parental care is predominantly the responsibility of the females, which provide nursing and protection until the young are mature enough to venture out on their own.

Conservation Status

According to the IUCN Red List, the White-footed Vole is currently considered to be of Least Concern. However, habitat destruction and pollution are potential threats that could impact their populations in the future. Continuous monitoring is essential to ensure their numbers remain stable.

Interesting Facts

One fascinating fact about the White-footed Vole is its ability to store food for use during the winter months. They create food caches by burying seeds and other edible items in their burrows. Additionally, despite their small size, these voles can be surprisingly territorial, especially during the breeding season.

Role in Ecosystem

The White-footed Vole plays a crucial role in its ecosystem as both a herbivore and prey species. By feeding on various plants, they help maintain the health of the vegetation in their habitat. Furthermore, their presence in the food web supports various predators, thus contributing to the overall balance of their ecosystem.
