Lovebirds may show how some parrots form lifelong bonds

Rosy-faced lovebirds, native to the Namib Desert, have likely established a pet-derived colony in Phoenix that may number about 2,000 birds; the species is noted for forming strong lifelong pair bonds and mutual grooming.

Rosy-faced lovebirds from the Namib Desert have established a substantial colony in Phoenix. The birds are believed to descend from pet birds and were first noticed around the city in the 1980s. Observers estimate the Phoenix population at about 2,000 birds. The birds are often seen roosting in holes in cactus and palm trees and sometimes near air-conditioning vents on very hot days. Observed details: - Rosy-faced lovebirds are native to the Namib Desert in southwestern Africa. - The Phoenix population is thought to have originated from escaped or released pet birds and was first reported in the 1980s. - Local observers estimate around 2,000 birds in the Phoenix area. - The birds roost in tree and cactus cavities and may gather near air-conditioning vents during extreme heat. - Lovebirds form long-term pair bonds; they preen each other and exchange regurgitated food as part of their social bonding. - The species typically lives about 20 years, and pet owners report signs of distress when a mate dies; pairs can also have brief conflicts before reconciling. Summary: The Phoenix colony illustrates the species' adaptability outside its native range and highlights characteristic lifelong pair bonds and social behaviors. Undetermined at this time.
