The mourning dove, known scientifically as Zenaida macroura, is a medium-sized, slender bird within the Columbidae family.

It is one of the most widespread and abundant birds in North America. This species is often recognized by its muted plumage and its distinctive, plaintive call. The name "mourning" comes from this doleful sound, which can sometimes be mistaken for an owl.

Despite being a popular gamebird, the species remains highly successful due to its prolific breeding habits. In warmer climates, a single pair can raise as many as six broods in one year. Each brood typically consists of two young birds, which are called squabs.

Physically, the mourning dove is built for efficient flight and survival.

Adults usually weigh between 120 and 150 grams, with a wingspan ranging from 37 to 45 cm. Their plumage is generally light gray-brown on top and a lighter, pinkish color underneath. A notable feature is the dark, crescent-shaped area of feathers located below the eye. Males are distinguished by bright, iridescent purple-pink patches on the sides of their necks. They also possess a bluish-grey crown, a feature that females lack. The species' scientific name, macroura, is derived from Ancient Greek words meaning "long-tailed," which describes their tapered tails.

The biology of the mourning dove includes unique methods of feeding and communication. While adults eat almost exclusively seeds, they provide a specialized substance called crop milk to their squabs. This liquid is produced in the parents' bodies to nourish the young.

In terms of sound, the doves utilize sonation, which is the production of sound through body parts. Their broad, elliptical wings create a distinctive whistling or fluttering sound during takeoff and landing. Some doves even perform a "wing clap" when they depart from a perch. Males use a specific cooing call to attract females, and they may also use a greeting call when returning to their mates.

Even the color of a mourning dove's feathers involves complex physics.

While feather colors are generally stable, research in 2011 suggested that iridescence can change based on external stimuli. This color is produced by thin-film interference. This occurs when light hits a single layer of keratin around the edge of feather barbules. Under this layer lies air and melanosomes. When environmental conditions like water change, the barbules can twist. This twisting exposes more surface area for reflection, increasing the brightness and color of the feathers by almost 50%.

The history of naming the mourning dove is a complex journey through scientific discovery.

In 1731, Mark Catesby described the bird in his work, *The Natural History of Carolina, Florida and the Bahama Islands*. He originally called it the "Turtle of Carolina." Later, in 1743, George Edwards included it in *A Natural History of Uncommon Birds*. In 1758, Carl Linnaeus attempted to organize these descriptions in his *Systema Naturae*, but he accidentally conflated the mourning dove with the passenger pigeon. It was not until 1952 that Francis Hemming proposed a solution to these naming errors. The International Commission on Zoological Nomenclature officially settled the names in 1955. The genus name *Zenaida* was introduced in 1838 by Charles Lucien Bonaparte.

Taxonomists recognize five distinct subspecies of the mourning dove, each adapted to specific regions.

The nominate subspecies, *Z. m. macroura*, is found in Cuba, Hispaniola, Puerto Rico, and Jamaica. The eastern subspecies, *Z. m. carolinensis*, lives in eastern North America and the Bahamas. The western subspecies, *Z. m. marginella*, ranges from western Canada to central Mexico. There is also the Panamanian subspecies, *Z. m. turturilla*, and the *Z. m. clarionensis*, which lives only on Clarion Island off the coast of Mexico. These subspecies vary slightly in beak length, wing shape, and color intensity.

Migration and habitat use are essential to the survival of the species.

Mourning doves occupy diverse environments, including farms, prairies, and urban areas, though they avoid thick forests and swamps. Many birds, particularly those in Canada, migrate long distances. They typically travel in flocks during the day at low altitudes. Spring migration occurs between March and May, while fall migration happens from September to November. During these movements, immatures usually move first, followed by adult females and then adult males. This widespread movement helps the species maintain its massive population across the Americas.
