No need to head to the movie theater or download the video game app: Angry Birds can be found right in your backyard this summer--if you live in the suburbs, that is.
Tech researchers recently found that birds that live in suburban areas exhibit significantly higher levels of territorial aggression than their country counterparts..
"A possible reason for this is that these birds have less space but better resources to defend," said Scott Davies, a postdoctoral associate in biological sciences. "Living near humans provides better food and shelter, but it also means more competition for these limited resources."
Davies and co-author Kendra Sewall, an assistant professor of biological sciences, measured territorial aggression in 35 urban and 38 rural male song sparrows at three rural and three urban sites.
