Information compression is a general principle of human language: the most frequent words are shorter in length (Zipf's Law Brevity) and duration constituents decreases as size linguistic construct increases (Menzerath-Altmann Law). Vocal sequences non-human primates have been shown to conform both these laws, suggesting information might be more principle. Here, we investigated whether display songs African penguin, which mediate recognition, intersexual mate choice territorial defence,...
Ensuring high standards of animal welfare is not only an ethical duty for zoos and aquariums, but it also essential to achieve their conservation, education, research goals. While some species, assessment frameworks are already in place, little has been done marine animals under human care. Responding this demand, the committee European Association Aquatic Mammals (EAAM) set up a group experts on science, cetacean biology, zoo medicine across Europe. Their objective was develop comprehensive...
An animal's ability to recognize another individual by matching their image voice suggests they form internal representations of other individuals. To what extent this ability, termed cross-modal recognition, extends birds than corvids is unknown. Here, we used an expectancy violation paradigm determine whether a monogamous territorial seabird ( Spheniscus demersus ) can cross-modally familiar conspecifics (partners or colony-mates). After pairs penguins spent time together in isolated area,...
The ability to vary the characteristics of one's voice is a critical feature human communication. Understanding whether and how animals change their calls will provide insights into evolution language. We asked what extent vocalizations penguins, phylogenetically distant species from those capable explicit vocal learning, are flexible responsive social environment. Using principal components (PCs) analysis, we reduced 14 parameters penguin's contact four PCs, each comprising highly...
Birds are known to be highly social and visual animals. Yet no specific feature has been identified responsible for individual recognition in birds. Here, using a differential looking paradigm across five experiments, we demonstrated that African penguins, Spheniscus demersus, spontaneously discriminated between life-size photographs of their monogamous, lifelong partner nonpartner colonymate ventral dot patterns. Our findings challenge the assumption limited involvement penguin...
