The Mourning Dove (Zenaida macroura) is one of North America’s most widespread and abundant bird species, often seen foraging for seeds on the ground during the day. While they spend active hours walking and feeding on open ground, they universally seek elevated shelter for sleep, a behavior known as roosting. A dove resting on the ground during daylight is common, but a dove sleeping there at night is highly unusual and generally indicates a compromised situation. This distinction between daytime foraging and nocturnal roosting is a fundamental survival strategy for the species.
Preferred Roosting Locations
Mourning Doves are diurnal, and they select specific locations to rest and sleep at night. Their choice of a nighttime perch is determined by the availability of cover, security, and proximity to feeding areas. They are highly adaptable habitat generalists, finding suitable roosts in diverse environments from rural farmlands to suburban neighborhoods.
The most common nocturnal perches are found in the branches of trees, favoring both dense coniferous evergreens and deciduous trees. These elevated spots offer concealment and protection from predators that cannot easily climb or fly. Outside of the nesting season, Mourning Doves often roost communally in small groups, a behavior that provides both increased security through shared vigilance and warmth during colder months.
Beyond natural structures, Mourning Doves readily utilize human-made alternatives, especially in urban areas. They can be found resting on utility lines, television antennas, and the ledges or eaves of buildings.
The Role of Safety in Choosing a Roost
The evolutionary drive to avoid sleeping on the ground is linked to the high risk of nocturnal predation. Mourning Doves are particularly vulnerable at night when they are less alert and their primary defense mechanism—rapid flight—is slowed. Ground-level locations expose them to a wide range of mammalian and reptilian predators.
Nocturnal hunters, such as raccoons, foxes, opossums, and snakes, can easily access a bird sleeping on the ground. Even domestic cats pose a significant threat to doves that spend time near the ground. By contrast, an elevated roost provides a clear, unobstructed flight path for a quick escape if a threat is detected. The distinct whistling sound their wings make upon takeoff is believed to serve as an alarm signal for nearby doves.
Elevation also provides protection from environmental factors. Roosting above the ground shields the birds from direct contact with cold, damp surfaces, which is especially important during winter. Choosing a sheltered perch conserves body heat and reduces the risk of exposure.
