The energetics of social signaling during roost location in Spix’s disc-winged bats
TLDR
The emission of contact calls significantly increases oxygen consumption and the costs of call production and resting metabolic rates may explain the differences in vocal behavior among individuals, providing support to the “allocation model”, which predicts that only individuals with lower self-maintenance costs can afford to spend energy in additional activities.
Harsh vocal elements affect counter-singing dynamics in male rock hyrax
TLDR
The findings suggest that the snort component is one of the main information transfer channels in male hyrax singing and can elicit conspecific singing even when isolated from other vocal elements, and support previous claims that harsh sounds constituteone of the key components in vocal communication.
Male hyraxes increase song complexity and duration in the presence of alert individuals
TLDR
Male hyraxes demonstrate a cognitive ability to optimize their advertising efforts in response to multiple types of events, and this is the first report of syntactic complexity of vocal signaling being altered following various triggers that change conspecifics mental state in terrestrial mammals.
Social context mediates testosterone's effect on snort acoustics in male hyrax songs
Rival assessment among northern elephant seals: evidence of associative learning during male–male contests
TLDR
The findings demonstrate that social knowledge of rivals alone can regulate dominance relationships among competing males within large, spatially dynamic social groups, and illustrate the importance of combining descriptive and experimental methods when deciphering the biological relevance of animal signals.
The progression pattern of male hyrax songs and the role of climactic ending
TLDR
It is suggested that animal vocal communication research can benefit from adding musical concepts to the analysis toolbox, as it is found that hyrax males tend to reply more to songs with a climactic ending, indicating that this progression pattern is important for hyrax communication.
At sea vocal repertoire of a foraging seabird
TLDR
The first detailed acoustic analysis of a foraging seabird is provided and context-specific acoustic structure in its vocalisations at sea is demonstrated, suggesting that seabirds use vocal communication to exchange various types of information that likely improves foraging success.

TLDR
The results imply that producing intensive advertising song in birds may incur a substantial cost in terms of increased energy expenditure.

Metabolic and Respiratory Costs of Increasing Song Amplitude in Zebra Finches
TLDR
This study measured oxygen consumption and respiratory patterns in adult male zebra finches singing at different amplitudes in different background noise conditions and found that oxygen consumption increased in higher background noise, independent of singing behaviour.
Complex call in male rock hyrax (Procavia capensis): a multi-information distributing channel
TLDR
The study reveals that hyrax songs provide accurate information regarding body weight, size and condition, social status and hormonal state of the singer, and implies that animals, through complex individual vocalizations, can potentially advertise multiple individual attributes in the same manner as that produced by chemical scent marking.
Individual identity is communicated through multiple pathways in male rock hyrax (Procavia capensis) songs
TLDR
In hyrax, individuality is expressed by highly variable, complex signals that are not condition dependent and are stable over years in singers that did not alter their spatial position, and it is shown that individuality signals are not linked to relatedness or to geographic location.
The energy cost of song in the canary, Serinus canaria
TLDR
Birdsong could act as a condition-dependent signal, since birds that are easily able to achieve energy balance could afford the cost of singing, but those close to their energy limits might not.
Singing is not energetically demanding for pied flycatchers, Ficedula hypoleuca
TLDR
Song production appears to be energetically cheap in the pied flycatcher in relation to the overall daily energy budget, because birds cannot sing and eat at the same time, and there could be an energetic constraint to song duration owing to the need to spend sufficient time foraging.

TLDR
A theory of acoustic communication is presented that shows that much of the heterogeneity in animal vocal signals can be explained based on the energetic constraints of sound production, and quantitative predictions on key features of acoustic signals, including the frequency, power and duration of signals are yielded.
Individual Acoustic Variation in Fallow Deer (Dama dama) Common and Harsh Groans: A Source-Filter Theory Perspective
TLDR
The results suggest that the sound source and the vocal tract resonances act together to determine groan individuality and that enough variation exists to potentially allow individual recognition based on groans.
The costs of singing in nightingales

TLDR
Singing at night is associated with increased overnight consumption of body reserves, which represents a significant metabolic cost of singing at night, which is consistent with those models of signalling in biology that predict or assume that honest signals are costly.
