What information is coded in bird alarm calls -- a new study from Korea
Recordings of the Oriental tit's alarm responses showed that alarm calls to snakes have special acoustic properties different from calls to chipmunks, even though both predators can enter bird's nests and destroy broods. Nestlings escaped from nests (and from the snake) when they heard a recording of the ''snake call'' but not ''chipmunk call'' by parents. This suggests that the calls do not carry information about predator's ability to enter the nest cavity, and that snakes are ''special'' predators. (2020-05-25)
