Mourning doves do not leave their babies once hatched; both parents actively care for and feed their young until they are ready to fledge. However, understanding the full scope of their parental behavior, nesting habits, and challenges faced by the chicks provides a clearer picture of how these birds raise their offspring.
Background on Mourning Doves
Mourning doves (Zenaida macroura) are one of the most widespread and recognizable bird species in North America. Known for their soft, mournful cooing calls, these birds are commonly found in woodlands, suburban areas, and open fields. Mourning doves are prolific breeders, capable of raising multiple broods in a single season, which typically spans from early spring through late summer.
How Mourning Doves Care for Their Babies
Once the female lays eggs, both parents share the responsibility of incubation, which lasts about 14 days. After hatching, the chicks—called squabs—are altricial, meaning they are born blind, featherless, and completely dependent on their parents for warmth and food.
Both the male and female mourning doves feed their young a specialized secretion known as “crop milk,” which is rich in fats and proteins. This crop milk is produced in the lining of the adult birds’ crops and is essential for the survival of the squabs during the first week or so after hatching.
Parents continue to feed the chicks a combination of crop milk and seeds until the squabs grow feathers and can start to digest solid food independently. This care usually extends for approximately 10 to 14 days after hatching, at which point the young are ready to leave the nest (fledge).
Nesting Habits and Parental Roles
Mourning doves build simple nests, often flimsy platforms of twigs placed in trees, shrubs, or even on man-made structures like window ledges or outdoor shelves. The nest is usually shallow and not heavily insulated, which means the parents must stay close to keep the eggs and chicks warm.
Both parents share incubation duties, taking turns sitting on the eggs, and both are involved in feeding the squabs. This cooperative care is vital since the chicks cannot regulate their body temperature and require frequent feeding.
Do Mourning Doves Abandon Their Babies?
While mourning doves generally do not abandon their babies, there are exceptions due to external factors such as predation, environmental stress, or human disturbance. Parents may temporarily leave the nest to avoid drawing attention to their young, but complete abandonment is rare.
In cases of extreme stress, illness, or injury to the parents, the chicks may be left unattended, which can lead to their death. However, it is important to note that mourning doves instinctively care for their young and will not leave them without cause.
Common Challenges Affecting Mourning Dove Families
Several factors can impact the survival of mourning dove chicks, including:
- Predators: Common predators include snakes, squirrels, cats, raccoons, and birds of prey, which may attack eggs or young squabs.
- Weather: Prolonged cold, rain, or heat can threaten the fragile chicks, especially since the nests are exposed and lightly constructed.
- Human Interference: Nest disturbance by people, pets, or lawn equipment can cause parents to temporarily abandon the nest or cause chicks to fall out.
- Food Availability: If food sources are scarce, parents may struggle to feed their young adequately, affecting growth and survival.
What Happens After Fledging?
After about two weeks, mourning dove chicks leave the nest but remain dependent on their parents for several more days. The fledglings learn to fly and forage under the watchful eyes of their parents until they become fully independent.
Unlike some bird species that might abandon fledglings soon after they leave the nest, mourning doves continue to care for and protect their young during this vulnerable stage.
Comparison With Other Birds’ Parental Care
Mourning doves differ from many bird species in their use of crop milk to feed their young—a trait shared with pigeons and flamingos but rare among birds in general. This nutritional strategy allows the parents to feed highly dependent chicks before they can digest seeds.
Additionally, compared to species that lay large clutches and may abandon weaker chicks, mourning doves typically lay 2 eggs per clutch and invest heavily in each chick, rarely abandoning them unless there is severe disturbance.
How to Help Mourning Dove Families
If you encounter a mourning dove nest or young birds, consider these tips to support their survival:
- Avoid disturbing nests or handling chicks; this can cause parents to abandon the site.
- Keep pets away from nesting areas.
- Provide water sources nearby but not directly under nests to avoid attracting predators.
- Plant native shrubs or trees to offer natural shelter and nesting spots.
- If you find a fallen chick, observe from a distance to see if parents return before intervening.
Frequently Asked Questions
Do mourning doves ever abandon their nests?
It is uncommon for mourning doves to abandon their nests without cause. Temporary absences may occur to avoid drawing attention, but parents usually remain committed unless disturbed or threatened.
What is crop milk and why is it important?
Crop milk is a nutrient-rich secretion from the adult doves’ crop lining, fed to hatchlings when they cannot yet digest seeds. It provides essential fats and proteins needed for early growth.
How long do mourning dove parents care for their young?
Parents care for their squabs by feeding and protecting them for about 2 weeks post-hatching, plus several days after fledging until the young can fly and forage independently.
Can humans successfully raise orphaned mourning dove chicks?
Raising orphaned mourning doves requires specialized care, including feeding crop milk substitutes and proper housing. It is best left to licensed wildlife rehabilitators to ensure proper development.
Why do mourning dove chicks sometimes leave the nest early?
Chicks may leave the nest prematurely due to disturbance, predation, or environmental stress, but normally they fledge only when fully feathered and capable of flight.
Are mourning doves protective of their nests?
While mourning doves do not aggressively defend their nests, they remain nearby and may perform distraction displays to draw predators away from their young.
