Dr Vladimir Dinets, a research assistant professor at the University of Tennessee, is a zoologist who studies animal behavior, ecology, and conservation. As of 2025, he also teaches mathematics at Rudgers University. He is the author of a recently published Frontiers in Ethology article that documents the impressive adaptation of an avian newcomer to the city. A Cooper’s hawk, a medium-sized raptor native to North America, appears to have learned how to adapt its hunting strategy and strike at a flock of birds precisely when cars at an intersection lined up after traffic lights switched to red, having been alerted by a sound signal that the red phase would last longer than usual. In the following guest editorial, he describes his observations.
