- Female birds have shorter lifespans than male birds, researchers findFemale mammals usually live longer than males, but a 27-year study of North American birds has found the opposite pattern in birds.
- Researchers at the University of California, Los Angeles (UCLA) analyzed more than 563,000 bird-banding records and found that adult female birds had a 12.4% lower survival rate than adult males across 35 bird species.
- The study, published in Proceedings of the Royal Society B, is the first large-scale research to examine differences in survival between male and female birds.
