AvatarByMargaret Shultz Dove, Pet & Companion Birds

Mourning doves are among the most familiar and beloved birds across North America, known for their gentle cooing and graceful presence in gardens, parks, and woodlands. Their soft, mournful calls have inspired poets and birdwatchers alike, but beyond their soothing sounds lies a fascinating story about their daily habits—especially what they eat. Understanding the diet of mourning doves not only enriches our appreciation of these birds but also helps in creating environments that support their survival and well-being.

These birds are primarily ground feeders, often seen pecking at seeds scattered across open spaces. Their feeding behavior is closely tied to their habitat and seasonal changes, which influence the availability of food sources. While seeds form the bulk of their diet, mourning doves also rely on other nutritional elements that sustain their energy and health throughout the year.

Exploring what mourning doves eat reveals insights into their role in the ecosystem and how they adapt to different environments. Whether you’re a casual observer or an avid bird enthusiast, gaining a better understanding of their dietary preferences can enhance your connection to these gentle creatures and the natural world they inhabit.

Typical Diet Components of Mourning Doves

Mourning doves primarily consume seeds, which constitute the bulk of their diet. Their feeding habits are highly adapted to ground foraging, where they pick up seeds from bare soil or low vegetation. Unlike some bird species that eat insects or fruits regularly, mourning doves rely heavily on plant-based foods, particularly seeds from a variety of plants. This diet provides the necessary carbohydrates and fats essential for their energy needs and overall health.

The seeds mourning doves favor come from agricultural crops, grasses, and weeds, reflecting their adaptability to different environments, including urban, suburban, and rural areas. Seeds from cultivated crops such as corn, millet, and sunflower are especially attractive to these birds and are frequently found in their diet when available.

Common Seeds and Foods Consumed by Mourning Doves

Mourning doves exhibit a preference for small, oily seeds that provide high energy content. Their diet includes a mix of native and introduced species, with seasonal variations depending on availability. During migration and colder months, they may rely more on cultivated seeds and grains provided by humans or found in agricultural fields.

Some of the most common seeds and food sources include:

  • Millet (white proso millet is highly favored)
  • Sunflower seeds (especially black oil sunflower seeds)
  • Corn (cracked or whole kernels)
  • Sorghum
  • Wheat and barley
  • Grass seeds
  • Weed seeds such as ragweed and lamb’s quarters

These seeds are readily available in many natural and human-modified environments, allowing mourning doves to thrive across a wide geographical range.

Seed Type Source Energy Content (kcal/g) Seasonal Availability
White Proso Millet Grasses/Weeds 3.5 Spring to Fall
Black Oil Sunflower Garden/Fields 5.0 Year-round
Corn (Maize) Agricultural fields 3.6 Fall to Winter
Sorghum Agricultural fields 3.8 Summer to Fall
Wheat Agricultural fields 3.4 Spring to Summer

Feeding Behavior and Adaptations

Mourning doves are ground feeders and possess a specialized feeding behavior that allows them to efficiently gather seeds from open areas. They typically forage in flocks, which can help reduce predation risk and increase foraging efficiency. Their bills are slender and slightly curved, ideal for picking up small seeds individually.

One interesting adaptation is their ability to swallow grit and small stones, which aid in the mechanical breakdown of seeds in their muscular gizzards. This adaptation allows them to digest hard seed coats effectively, improving nutrient absorption.

Additionally, mourning doves have a crop, a specialized pouch-like structure, where food can be stored and softened before digestion. This allows them to gather food quickly and digest it later in a safer location.

Supplemental Foods and Occasional Diet Items

While seeds form the core of their diet, mourning doves occasionally consume other food items to supplement their nutrition:

  • Small berries and fruits: These provide additional vitamins and moisture.
  • Insects and snails: Rarely consumed but occasionally ingested, especially by young birds requiring protein.
  • Green plant material: Tender shoots or leaves may be eaten during scarcity.

These supplemental foods are not a major part of their diet but can contribute to a balanced nutritional intake, particularly during breeding or when seed availability is low.

Feeding Mourning Doves in Captivity or Backyard Settings

For those interested in attracting or feeding mourning doves, offering appropriate seeds can support their health and natural behaviors. Commercial birdseed mixes often include millet and sunflower seeds, which are ideal. Providing clean, fresh water nearby is also crucial for their well-being.

Some recommendations for feeding include:

  • Use a flat tray or platform feeder to accommodate ground-feeding habits.
  • Avoid mixes with large quantities of filler seeds like oats or red millet, which are less preferred.
  • Keep feeding areas clean to prevent disease.
  • Offer grit or crushed oyster shell to aid digestion.

By understanding their natural diet and feeding behaviors, one can effectively support mourning doves in both wild and controlled environments.

Dietary Habits of Mourning Doves

Mourning doves primarily consume seeds, which constitute the bulk of their diet throughout the year. Their feeding habits reflect their adaptation to a granivorous lifestyle, relying on a variety of seeds from native plants, agricultural crops, and occasionally small amounts of vegetation and insects.

These birds are ground feeders, often foraging in open areas such as fields, lawns, and roadsides. Their preference for seeds is due to both nutritional needs and the availability of food sources in their habitat.

Common Food Sources

  • Grass Seeds: Seeds from native grasses like crabgrass and foxtail are frequently consumed.
  • Weed Seeds: Seeds from plants such as ragweed, sunflower, and lamb’s quarters are common components.
  • Agricultural Seeds: Mourning doves often feed on leftover grains from crops such as millet, corn, wheat, sorghum, and barley.
  • Tree Seeds and Fruits: Occasionally, small seeds from trees like pine and fruits from shrubs are eaten.
  • Insects and Snails: Though primarily seed eaters, mourning doves will consume small insects and snails during the breeding season to increase protein intake.

Seasonal Variations in Diet

The diet of mourning doves varies with seasonal availability of seeds and supplementary food sources:

Season Primary Food Sources Dietary Notes
Spring Early grass and weed seeds, insects Increased insect consumption for protein during nesting
Summer Seeds from mature grasses, weeds, and crops High seed consumption; insects still supplement diet
Fall Abundant weed and crop seeds, fallen fruits Focus on energy-dense seeds for fat storage
Winter Persistent weed seeds, leftover grains Limited insect availability; seeds remain primary food

Feeding Behavior and Adaptations

Mourning doves possess several physical and behavioral adaptations that facilitate their seed-based diet:

  • Beak Structure: Their slender, pointed beak is well-suited for picking up small seeds from the ground.
  • Crop Function: The crop stores food temporarily, allowing doves to consume large quantities of seeds quickly and digest them gradually.
  • Water Intake: Mourning doves drink water regularly to aid in seed digestion and maintain hydration.
  • Foraging Strategy: They often feed in flocks, which increases efficiency and provides safety from predators.

Feeding Mourning Doves in Captivity or Backyard Settings

For those interested in attracting or feeding mourning doves, providing appropriate food items can support their health and natural behaviors:

  • Seed Mixes: A mix containing millet, cracked corn, safflower, and sunflower seeds is highly attractive.
  • Water Source: Fresh water should always be available to encourage natural feeding and hydration.
  • Feeding Platforms: Ground feeders prefer open, flat surfaces or low trays to mimic natural foraging grounds.
  • Avoid: Bread or processed human foods, which do not meet their nutritional needs and can be harmful.
