A groundbreaking study published in *Ecology and Evolution* has revealed that masturbation is a prevalent and natural behavior among birds, challenging long-held assumptions about animal behavior. Led by Dr. Chloe Heys from the University of Lancashire, the research involved data from scientific literature and surveys from bird keepers. It found that masturbation occurs across both sexes and various age groups, with juvenile birds engaging in this behavior almost as frequently as adults. Contrary to previous beliefs that masturbation in captive birds indicated stress, the study shows that it is more common in wild birds, suggesting it is a healthy part of their sexual behavior. The findings also link the frequency of masturbation to mating systems, indicating that species with multiple partners are more likely to engage in this behavior. This study highlights the importance of understanding animal behavior without the biases of human social taboos.
