Lovebirds demonstrate lifelong pair bonds and social care

Rosy-faced lovebirds in Phoenix, thought to number about 2,000, form lifelong pairs and frequently groom and feed each other.

Rosy-faced lovebirds are small parrots now common in parks around Phoenix. They are thought to be descendants of pet birds and were first noticed in the 1980s. Arizona is believed to host the largest colony of rosy-faced lovebirds outside southwestern Africa, with an estimated 2,000 birds. The birds roost in holes in cactus and palm trees and are often seen near air-conditioning vents on very hot days. Key facts: - Native range: Rosy-faced lovebirds originate from the Namib Desert in southern Africa. - Phoenix colony: The local population is estimated at about 2,000 birds and likely began from escaped or released pets. - Social bonds: Lovebirds typically form long-term, often lifelong, pair bonds and perch closely together. - Mutual care: Pairs commonly groom each other and pass food between beaks; the food exchange is reported as regurgitated. - Lifespan and behavior: They generally live around 20 years and can show both affectionate behaviors and occasional aggression, such as screaming or pecking. - Other colonies: Similar rosy-faced populations are reported in parts of Hawaii, and a different lovebird species has a small colony in Portugal. Summary: Their frequent grooming, food-sharing and close perching are noted as central to their enduring pair bonds and have been linked to the species' resilience in nonnative urban settings.
