How do pigeon courtship displays help form a pair bond?

In pigeons, courtship displays are essential for establishing and maintaining a pair bond by reducing aggression and fear between potential mates.1

The process typically involves the following stages:

• Initial Interaction: A sexually mature male attracts an unmated female using display flights, which include exaggerated movements, slow wing beating, and loud wing clapping.1
• Bowing Display: Once a female enters his territory, the male performs a "bowing display," which is inherently aggressive but accompanied by a "bow call." The female initially responds with submissive postures.1
• Appeasement and Bonding: As the female shows receptivity, the male’s aggression decreases, and he transitions to a "nest demonstration" display. This submissive behavior reduces the female's fear and draws her closer.1
• Cementing the Bond: The pair bond is further solidified through mutual nibbling of each other's feathers, particularly around the head and neck. During this phase, the female often exhibits juvenile food-begging behavior, which the male satisfies by feeding her, reinforcing their social connection.1

These ritualized interactions allow the birds to overcome their natural aversion to close contact, facilitating successful cooperation for nesting and rearing young.12
