Bottlenose dolphins (Tursiops truncatus) produce individually distinctive signature whistles that broadcast the identity of the caller. Unlike voice cues that affect all calls of an animal, signature whistles are distinct whistle types carrying identity information in their frequency modulation pattern. Signature whistle development is influenced by vocal production learning. Animals use a whistle from their environment as a model, but modify it, and thus invent a novel signal. Dolphins also… 

Automated Detection of Dolphin Whistles with Convolutional Networks and Transfer Learning

This paper shows that convolutional neural networks can indeed outperform traditional automatic methods in a challenging detection task: identification of dolphin whistles from underwater audio recordings, and further support the adoption of artificial intelligence technology to improve the automatic monitoring of marine ecosystems.

Mechanisms of auditory masking in marine mammals

Anthropogenic noise is an increasing threat to marine mammals that rely on sound for communication, navigation, detecting prey and predators, and finding mates. Auditory masking is one consequence of

Individual Differences in the Vocal Communication of Malayan Tapirs (Tapirus indicus) Considering Familiarity and Relatedness

The vocalizations of 14 captive adult Malayan tapirs investigated whether familiarity or relatedness had an influence on call similarity, and the results support the view that solitary animals could have individual distinct calls, like highly social animals.

First description of whistles of Black Sea short-beaked common dolphins, Delphinus delphis ponticus

ABSTRACT The study presents the first quantitative description of whistles (N = 1,017) recorded from free-range short-beaked common dolphins D. delphis ponticus, an endemic subspecies from the Black
