The eastern cottontail rabbit is a familiar sight in backyards, fields, and meadows across North America. To understand how these energetic herbivores thrive in diverse habitats, it is essential to look at their dietary habits, which shift with the seasons and availability of plants.
Core Components of the Eastern Cottontail Diet
At the heart of the eastern cottontail's nutrition is a high-fiber, plant-based menu focused on grasses and forbs. These rabbits are considered concentrate selectors, meaning they prefer nutrient-dense parts of plants while leaving behind tougher fibers. Their digestive system is specialized to extract maximum energy from fibrous material through cecotrophy, a process where special soft fecal pellets are re-ingested to absorb vital nutrients.
Favorite Foods in Warm Seasons

During the spring and summer months, the menu expands to include a variety of lush vegetation. Preferred items often include:
- Various cool-season and warm-season grasses that provide bulk and energy.
- Broadleaf plants and weeds such as dandelion, plantain, and chickweed.
- Garden crops like lettuce, carrots, and cruciferous vegetables.
- Young shoots, twigs, and bark from shrubs and ornamental trees when other options are scarce.
Surviving Winter Scarcity
When snow covers the ground and fresh growth disappears, the diet of the eastern cottontail becomes more conservative. They rely heavily on twigs, buds, and the bark of woody plants. Evergreen shrubs and trees, such as dogwood and conifers, become a critical food source during this lean period. Their ability to switch from a grazing diet to a browsing diet is key to their survival in colder climates.
Impact on Gardens and Landscapes
Because of their varied appetite, eastern cottontails can become unwelcome guests in cultivated spaces. They show little hesitation in feasting on prized annuals, vegetables, and fruit trees. Gardeners often notice cleanly clipped stems and distinctive round fecal pellets as clear signs of activity. Protecting young plants with fencing or repellents is often necessary in areas with high rabbit populations.
Nutritional Needs and Feeding Habits
To meet their high metabolic rate, eastern cottontails must feed frequently, often at dawn and dusk. They require a balance of protein, fiber, and minerals. While they consume a significant amount of greenery, they also seek out sources of moisture. The table below outlines the primary nutritional components of their seasonal diet:
| Season | Primary Food Sources | Key Nutritional Benefit |
|---|---|---|
| Spring/Summer | Grasses, herbs, leafy greens | High moisture and protein for growth |
| Fall/Winter | Bark, buds, twigs, evergreens | Fiber and structural carbohydrates for energy |
Water and Hydration
Although they obtain moisture from the plants they eat, eastern cottontails readily drink standing water when available. Puddles, birdbaths, and dripping outdoor faucets are common targets for hydration. Their need for consistent water intake becomes particularly critical during hot weather and when consuming dry winter forage.
