The article about interspecific social learning of novel mobbing calls recognition in birds authored by Jakub Szymkowiak has been published in Animal Behaviour! The study provides experimental evidence that birds can learn to recognize novel heterospecific mobbing calls through interspecific social learning, by associating mobbing calls of a previously unknown species with those of the already recognized heterospecifics during joint mobbing events.
