The phenomenon of animal divorce gained attention with the split of Bibi and Poldi, two Galápagos tortoises, after 115 years together.
In nature, social monogamy is rare among mammals, with less than 10% forming lasting pair bonds, contrasting with many bird species.
Research shows that birds often engage in mating beyond social bonds, as seen in studies of species like the fairywren with high rates of infidelity.
Environmental factors, including climate change, can influence divorce rates, as evidenced by studies on snow petrels and black-browed albatrosses.
Such findings highlight that both pairing success and breakups in the animal kingdom are shaped by ecological conditions and species-specific behaviors.
