The adaptability of the White-winged Dove’s diet is a key factor in their ability to colonize a wide range of habitats. During the breeding season, their nutritional requirements increase, prompting them to seek additional food sources, including insects, to provide for their young. This varied diet allows them to maintain a healthy population across their expansive range, demonstrating the species’ resilience and flexibility in foraging behavior.
Mating Behavior:
Mating Description:
White-winged Doves are monogamous during the breeding season, engaging in various courtship behaviors to attract mates. Males perform impressive display flights, rising steeply into the air before gliding down a circular path while emitting distinctive cooing calls. This aerial display is complemented by ground displays, where the male puffs up his feathers and struts around the female.
Nesting sites are chosen by pair members, who prefer locations that offer protection from predators and the elements. The nests are simple platforms of twigs, built-in trees, shrubs, or even man-made structures. Females typically lay two eggs, which are incubated by both parents, reflecting their cooperative approach to reproduction. The adaptability of their nesting behavior to include urban environments has contributed to the species’ population growth and range expansion.
