Nestling birds struggle in noisy environments

29 octubre 2014

Unable to fly, nestling birds depend on their parents for both food and protection: vocal communication between parents and offspring helps young birds to determine when they should beg for food and when they should crouch in the nest to avoid a predator seeking an easy meal. A group of researchers has found that ambient, anthropomorphic noise — from traffic, construction and other human activities — can break this vital communications link, leaving nestlings vulnerable or hungry.
