Angrier birds

Yet another study comparing the lives of city birds and country birds found that those living in urban areas are “angrier” than their rural counterparts, exhibiting significantly higher levels of territorial aggression.

“A possible reason for this is that these birds have less space but better resources to defend,” said Scott Davies, a Virginia Tech University researcher who conducted the study.

He added that living around humans gives birds better shelter, but also means there is more competition for limited urban food.
