Do Mourning Doves Stay Together for Life? The Enduring Bonds of a Beloved Bird
The prevailing answer is yes, mourning doves exhibit strong pair bonds and frequently remain together for life, returning to the same nesting sites season after season. Do mourning doves stay together for life? largely depends on the pair successfully navigating environmental challenges and avoiding predation.
Understanding Mourning Dove Pair Bonds
The gentle cooing and graceful flight of the mourning dove (Zenaida macroura) make it a familiar and cherished sight across North America. But beyond their aesthetic appeal, mourning doves exhibit fascinating social behaviors, most notably their tendency towards lifelong pair bonds. Understanding this behavior involves exploring several key aspects of their biology and ecology.
-
Courtship Rituals: The bond formation begins with elaborate courtship rituals. The male mourning dove will display to the female, bowing, cooing, and performing short flights to impress her. He’ll also offer her food, a clear indication of his ability to provide for her and their future offspring.
-
Shared Responsibilities: Once paired, mourning doves share equally in the responsibilities of nesting, incubation, and raising their young. This cooperative approach strengthens their bond and increases the survival rate of their offspring. Both parents incubate the eggs, alternating shifts to ensure the eggs remain at the optimal temperature.
-
Fidelity and Longevity: While the phrase “for life” might seem absolute, it’s important to consider the realities of the wild. A mourning dove’s lifespan in the wild is typically 1 to 5 years. Therefore, lifelong fidelity translates to remaining with a partner for the duration of their natural lives, barring unforeseen circumstances such as death or injury.
The Benefits of Lifelong Pairing
There are several compelling reasons why mourning doves have evolved to form such strong pair bonds. These benefits extend to both individual doves and the overall population.
-
Increased Reproductive Success: Established pairs are generally more successful at breeding than new pairs. They already know each other’s strengths and weaknesses, have established efficient nesting routines, and are better at defending their territory.
-
Efficient Resource Management: By staying together, mourning doves can more efficiently find and defend food sources, locate suitable nesting sites, and protect themselves from predators. Their shared knowledge and cooperation contribute to their survival.
-
Reduced Energy Expenditure: The process of finding a new mate each breeding season requires significant energy expenditure. Mourning doves save energy by maintaining their existing pair bond, allowing them to focus on breeding and raising their young.
Factors Affecting Pair Bond Longevity
While mourning doves are known for their fidelity, several factors can disrupt their pair bonds. Understanding these factors provides a more nuanced perspective on their relationship dynamics.
-
Predation: The most common reason for the dissolution of a mourning dove pair bond is the death of one partner due to predation. Mourning doves are preyed upon by a variety of animals, including hawks, falcons, snakes, and domestic cats.
-
Injury and Illness: If one mourning dove becomes injured or ill and is unable to perform its duties within the pair, the other partner may abandon the relationship in search of a healthier and more capable mate.
-
Habitat Loss and Degradation: Loss of suitable nesting sites and food sources can also disrupt pair bonds. If a pair is unable to find adequate resources in their territory, they may be forced to separate in search of better opportunities.
Comparing Mourning Dove Pair Bonds to Other Bird Species
The phenomenon of lifelong pairing is not unique to mourning doves, but it’s not universal among bird species either. Understanding how their behavior compares to other birds provides valuable context.

Frequently Asked Questions About Mourning Dove Pair Bonds
Do both mourning doves help build the nest?
Yes, both mourning dove parents participate in nest building, although the male typically gathers the materials while the female constructs the simple platform nest. This shared responsibility reinforces their bond and contributes to the success of their breeding efforts.
What happens if one mourning dove dies?
If one mourning dove dies, the surviving partner will typically seek out a new mate. While they form strong bonds, survival instincts ultimately prevail. They will mourn the loss of their partner. However, they will eventually seek a new mate to continue breeding.
How can I tell if two mourning doves are a mated pair?
Mated pairs are often seen together, preening each other, and engaging in mutual cooing. They will also defend their territory against other mourning doves. Observing these behaviors can indicate a strong pair bond.
Do mourning doves migrate together?
Whether mourning doves migrate together depends on the specific population. Some populations are migratory, while others are resident year-round. Migratory pairs will often travel together, reinforcing their bond during the arduous journey.
Do mourning doves only have one brood per year?
No, mourning doves are prolific breeders and can have multiple broods per year, sometimes up to six in warmer climates. Their strong pair bonds contribute to their ability to raise so many young.
What do mourning doves eat?
Mourning doves are primarily seed-eaters, consuming a variety of seeds from grasses, weeds, and cultivated crops. They may also eat small grains and insects. Both parents will feed their young “crop milk,” a nutritious substance secreted from their crop lining.
How long do mourning dove eggs take to hatch?
Mourning dove eggs typically take about 14 days to hatch. Both parents share the responsibility of incubation, ensuring the eggs remain at a constant temperature for optimal development.
Are mourning doves monogamous?
The term monogamous can be debated, but mourning doves exhibit strong pair bonds and typically remain with the same partner for life, which is considered social monogamy. Genetic studies would be required to determine whether extra-pair copulations occur.
What are the main threats to mourning doves?
The primary threats to mourning doves include predation (especially from raptors and domestic cats), habitat loss, collisions with vehicles and windows, and hunting in some areas. They are also susceptible to diseases.
How can I attract mourning doves to my yard?
You can attract mourning doves to your yard by providing a source of fresh water, such as a bird bath, and offering birdseed, particularly millet and sunflower seeds. Planting native trees and shrubs that provide cover and nesting sites will also encourage them to visit.
Why are mourning doves called mourning doves?
Mourning doves are named for their distinctive, plaintive cooing call, which sounds somewhat like a person mourning. This melancholy sound is a characteristic feature of their vocalizations.
Do mourning doves stay with their young after they fledge?
Mourning doves typically care for their young for about two weeks after they fledge, teaching them how to find food and avoid predators. After this period, the young doves become independent and the parents begin preparing for their next brood. The pair bond continues even as they care for their young.
