Birds Are More Afraid of Women Than of Men
Nautilus | Science • • science
Key Points:
- A study published in People and Nature found that urban birds in Europe tend to flee sooner from women than men, allowing men to approach over three feet closer on average before flying away.
- The research, involving 37 bird species across five countries, showed consistent differences in flight initiation distance based on the sex of the approaching human, but the cause remains unexplained.
- Researchers ruled out factors like hair length, body size, and height, suggesting birds might detect subtle visual or odor cues to differentiate between men and women.
- One speculative theory proposes an evolutionary background where women historically hunted smaller prey like birds, leading to birds developing a greater fear of women, though this explanation lacks strong evidence.
- Despite extensive analysis, the research team acknowledges the mystery remains unsolved and calls for further investigation into why urban birds exhibit this sex-based fear response.
