A new study has revealed that birds living in cities appear to be more fearful in the presence of women than men.
According to details, researchers observed 37 different species of birds found in urban areas across five European countries during a study published in the journal People and Nature in December 2025. The findings showed that the birds tended to fly away more quickly when women approached them compared with men.
According to the research, birds are capable of distinguishing between the genders of approaching humans.
Researchers closely examined the distance at which birds decided to leave their position and fly away when a person approached them.
The study found that, on average, men were able to approach nearly one metre closer before the birds reacted and flew off.
Professor John Marzluff of the University of Washington said the findings remain preliminary. He noted that although birds possess the ability to recognise humans, the scientific reasons behind their differing reactions based on gender have yet to be fully understood.
