Study Reveals Sparrows Become Less Social with Age

Research shows older sparrows, like humans, form fewer friendships and become more selective in social interactions.

A study on Lundy Island tracked sparrows' social behaviors from 2000, revealing a decline in social contacts as they age.
Older sparrows not only lose connections with peers but also form fewer new social bonds.
The research suggests that young sparrows benefit evolutionarily from friendliness, impacting their reproductive success.
The findings draw parallels between sparrows and humans, highlighting similar social patterns in aging.
Sparrow populations are widespread globally, yet their numbers have been declining significantly in recent decades.
