The Mourning Dove (Zenaida macroura) is one of North America’s most widespread birds, recognizable by its slender tail and brown-gray plumage. Its characteristic “coo-OO-oo” call, often described as mournful, is primarily used by the male to attract a mate and defend his territory during the breeding season. If this familiar sound has gone silent in your yard, it may be a temporary shift in behavior or signal deeper environmental changes making the area less hospitable.
Understanding Natural Cycles of Absence
The apparent absence of Mourning Doves is often due to predictable shifts in their daily and seasonal routines. Doves are partially migratory; some populations remain year-round, while others travel south for the winter. The timing of these movements varies based on local climate and food availability. Their presence fluctuates seasonally, with the largest numbers often observed during spring and fall migrations.
Daily activity patterns influence when calls are heard, as doves are most vocal during two distinct periods. Peak morning activity is typically concentrated between 5:30 a.m. and 9:00 a.m., with a secondary peak in the late afternoon between 4:00 p.m. and 7:30 p.m. Outside of these times, the birds are often silent and loafing on elevated perches. Immediate weather conditions can also temporarily suppress vocalization; doves are less active and less audible during heavy rain or high winds.
Local Environmental Shifts
Mourning Doves are habitat generalists, thriving in open or semi-open environments, but their presence links tightly to immediate local resources. They are primarily ground feeders, consuming nearly 99% seeds collected from bare soil or sparse vegetation. Changes that cover the ground—such as heavy mulch, dense ground cover, or thick leaf litter—eliminate feeding opportunities, causing them to move elsewhere.
The loss of specific nesting and roosting cover also contributes to local displacement. Doves build flimsy nests in trees, dense shrubs, or on man-made structures, often preferring the edges of clearings over deep forest interiors. Removing a favorite hedge or patch of vines eliminates a safe breeding location, forcing the pair to seek a new territory. They also require accessible water sources. The lack of a reliable, open water feature, such as a ground-level birdbath, can motivate them to relocate entirely.
Increased human activity and noise pollution can stress these birds, making a comfortable location feel unsafe. Doves are easily startled, and their characteristic wing-whistle upon rapid take-off serves as an alarm signal. Construction, heavy traffic, or continuous noise can mask their communication and reduce their sense of security, especially near feeding sites where they are vulnerable. Localized changes in food, water, cover, and safety drive a sudden decline in dove presence.
Factors Causing Population Decline
A genuine decline in the local Mourning Dove population can be attributed to increased mortality from environmental and biological threats. One cause of death is the parasitic disease Avian Trichomoniasis, or canker, caused by the protozoan Trichomonas gallinae. This parasite causes lesions in the mouth and throat, preventing the bird from swallowing or breathing. The disease transmits easily at communal feeding and watering sites when infected birds shed the parasite into food or water.
Predation pressure from both native and non-native species also plays a role in dove mortality. The recovery of raptor populations, such as Cooper’s Hawks and Sharp-shinned Hawks, has increased their hunting success against doves. Domestic and feral cats are a major threat, as doves forage on the ground where they are easily ambushed.
Human-caused hazards contribute to mortality, including collisions with windows. The widespread use of pesticides and herbicides reduces the seed-producing “weeds” that form the bulk of the dove’s diet, leading to starvation or reduced reproductive success. Furthermore, the intensification of agriculture, specifically the expansion of corn and soybean monocultures, has been linked to reduced reproductive output in the eastern United States, likely due to a lack of preferred small-grain seeds.
Encouraging Doves to Return
To make your property more attractive to Mourning Doves, focus on providing their requirements for feeding, drinking, and security. The most effective way to provide food is by scattering preferred seeds directly onto a bare patch of ground or using a low, wide platform feeder. Doves favor small seeds like white millet, cracked corn, and black oil sunflower seeds, which they consume and store quickly in their crop before flying to a safe perch for digestion.
Providing a clean, accessible water source is equally important, as doves must drink regularly. They have the unique ability to suck water rather than scoop and tilt their heads. A shallow birdbath with a maximum depth of one to two inches is ideal, especially if placed in an open area that allows a clear view of predators. To mitigate the risk of disease transmission, particularly Avian Trichomoniasis, clean all feeders and birdbaths weekly with a diluted bleach solution (one part bleach to nine parts water).
Finally, offer secure, dense cover for nesting and roosting near the feeding and watering sites. Doves utilize dense shrubs, thick evergreen trees, or man-made nesting shelves mounted between seven and twelve feet high. Maintaining a few large, dead tree limbs or bare wires also provides the high-visibility perches they use for loafing and cooing, making the area feel safer and more established.
