White-winged Dove

The White-winged Dove (Zenaida asiatica) is a robust bird, notable for its size among doves, measuring approximately 29 cm from beak to tail with a wingspan ranging from 48 to 58 cm. Its plumage is primarily brownish-gray to gray, with a striking white edge on its wings, visible even when perched. The species is adorned with a blue eyering and possesses red eyes, though juveniles display brown eyes and a duller plumage.

Identification Tips

To identify the White-winged Dove, look for the distinctive white wing patch, visible at rest and in flight, which sets it apart from similar species. Adults feature a blue, featherless skin around the eyes and a dark facial mark. Males may exhibit a more iridescent purple hue on the crown, neck, and nape, and a more pronounced ear spot, though these differences are subtle. The species has a short, rounded tail, contrasting with the long, pointed tail of the Mourning Dove.

Habitat

The White-winged Dove is found in a variety of environments, including deserts, scrubs, urban areas, and agricultural landscapes. It has adapted well to human-altered habitats and can be seen in high concentrations near sources of water and food.

Distribution

Native to the Southwestern United States, Mexico, Central America, and the Caribbean, the White-winged Dove's range has expanded due to human agricultural practices. It is now a year-round resident in places like Texas and has been observed as far north as Canada and Alaska.

Behaviour

This species can form migratory flocks of up to 4,000 individuals, though it is also known to overwinter in certain areas. It has a remarkable ability to fly considerable distances in search of water, but can also rely solely on the moisture found in saguaro cactus fruit.

Song & Calls

The White-winged Dove's call is reminiscent of the phrase "who cooks for you," and it also produces a series of "pep pair pooa" calls. Males use a dedicated perch for cooing, primarily during the breeding season. Nonvocal sounds include a wing whistle upon take-off and heavy wing beats.

Breeding

Breeding behavior includes males displaying with spread wings and fanned tails. The species constructs flimsy stick nests in trees and lays two cream-colored to white eggs. Nestlings can fledge as early as 2-3 months old, and families often remain together for life.

Similar Species

The Mourning Dove is similar in appearance but can be distinguished by its longer, pointed tail and lack of white wing edges. The White-tipped Dove and Eurasian Collared Dove also lack the white wing edging and have different coloration and markings.

Diet and Feeding

Primarily granivorous, the White-winged Dove feeds on seeds, grains, and fruits. It has a particular affinity for the pollen, nectar, and fruit of the saguaro cactus. In agricultural settings, it can become a pest, descending on grain crops in large numbers.

Conservation Status

Despite historical population declines due to habitat loss, hunting, and other human impacts, the White-winged Dove has shown remarkable adaptability to human environments. It is currently classified as a species of least concern by the International Union for Conservation of Nature (IUCN).
