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… 

Signature whistles in wild bottlenose dolphins: long-term stability and emission rates

The decades-long occurrence of whistles with stereotyped frequency contours in a population of wild bottlenose dolphins, resident in the region of the Sado estuary, Portugal, is documented, and confirmed stereotypy throughout more than 20 years suggests that the identified stereotyped whistles are in fact signature whistles.

Evidence for vocal signatures and voice-prints in a wild parrot

Mon monk parakeets may be able to use vocal cues to recognise conspecifics, even across vocalisation types and without necessarily needing active vocal signals of identity, and voice-prints across call types are provided.

Automated detection of dolphin whistles with convolutional networks and transfer learning

This paper shows that convolutional neural networks can indeed significantly 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.

Silbido profundo: An open source package for the use of deep learning to detect odontocete whistles.

This work presents an open-source matlab software package for exploiting recent advances in extracting tonal signals from large acoustic data sets. A whistle extraction algorithm published by Li,

Vessel traffic influences distribution of Aotearoa New Zealand's endemic dolphin ( Cephalorhynchus hectori )

The findings suggest that Hector's dolphins at Akaroa Harbor were displaced from core habitat in response to each of these vessel traffic parameters, and managers should use immediately actionable tools to reduce the impacts of vessels on these dolphins.

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

Parameterizing animal sounds and motion with animal-attached tags to study acoustic communication

This work parameterized dolphin vocalizations and motion to investigate how senders and receivers modified movement parameters as a function of signal parameters, and used high-resolution tag data to parameterize dolphin sounds and motion and applied continuously sampled parameters to examine how individual dolphins responded to conspecifics’ signals and moved while producing sounds.

The potential for acoustic individual identification in mammals

The greatest potential for AIID (characterized by strong and stable acoustic signatures) was in Cetacea and Primates (including humans), and in species with weaker acoustic signatures, AIID could still be a valuable tool once its limitations are fully acknowledged.

A simple tool for linking photo-identification with multimedia data to track mammal behaviour

Identifying individual animals is critical to describe demographic and behavioural patterns, and to investigate the ecological and evolutionary underpinnings of these patterns. The traditional

Characterizing the Long-Term, Wide-Band and Deep-Water Soundscape Off Hawai’i

Many animals use sound for communication, navigation, and foraging, particularly in deep water or at night when light is limited, so describing the soundscape is essential for understanding,
