<< animals with shared predators can eavesdrop on and respond to each other's calls, indicating that they can partly understand other species. >>
<< Many birds have specific alarm calls, warning others about a predator, (..) I was studying how a specific call of a small bird named the Japanese tit, Parus minor, evokes a visual image of the predator in their minds, in particular, a snake. >> Toshitaka Suzuki.
<< But he then observed that another bird, the coal tit or Periparus ater, also often approached the experimental area during these alarm calls. >>
<< I wondered if these other birds also mentally retrieve 'snake' images from these calls. While they are in the same taxonomic group their calls are otherwise vastly different. >> Toshitaka Suzuki.
