IndiaA 27-year study conducted by researchers at the University of California, Los Angeles (UCLA), analyzing over 563,000 bird-banding records, found that female birds have a significantly lower survival rate compared to males. Across 35 bird species, adult female birds had a 12.4% lower survival rate than males, living an average of 1.36 years after reaching adulthood versus 1.61 years for males. The study, published in the journal 'Proceedings of the Royal Society B,' used data collected from 1992 to 2018 by the Institute for Bird Populations. Researchers noted that female birds face greater challenges due to the physical demands of migration and reproduction, particularly in species that migrate long distances or have specific flight characteristics. The findings challenge previous assumptions about gender-based longevity patterns in animals.

While the study highlights biological differences between male and female birds, there is no indication of political bias or agenda-driven interpretation. The tone remains objective, focusing on empirical data rather than a左
