Urban Birds Appear to Fear Women More Than Men, But Why?

A multi-country European study found that 37 urban bird species let men approach about one meter closer than women before flying off.

The difference appeared across France, Germany, Poland, Spain, and Czechia, but researchers do not yet know the cause.

The result challenges the idea that birds respond to humans in a neutral way and may point to subtle sex-linked cues.

Researchers say the finding could matter for wildlife field studies and urban ecology, where human presence can affect bird behavior.
