Mimicry is a classical example of adaptive signal design. Here, we review the current state of research into vocal mimicry in birds. Avian vocal mimicry is a conspicuous and often spectacular form of animal communication, occurring in many distantly related species. However, the proximate and ultimate causes of vocal mimicry are poorly understood. In the first part of this review, we argue that progress has been impeded by conceptual confusion over what constitutes vocal mimicry. We propose a… 
Jack of All Calls and Master of Few: Vocal Mimicry in the Tawny Lark (Galerida Deva)
A detailed account of the variety of mimetic sounds produced by the Tawny Lark is provided and acoustic and peer-based analyses that gauge the accuracy of the mimicry are described.
Mimicry for all modalities.
A novel conceptual framework whereby mimicry evolves if a receiver perceives the similarity between a mimic and a model and as a result confers a selective benefit onto the mimic and shows that imperfect mimicry is expected to be the norm.
Evolutionary origins of vocal mimicry in songbirds
The evolutionary history of vocal mimicry across the avian phylogeny is traced using ancestral trait reconstruction on a dataset of oscine passerines, finding that the common ancestor to oscines was unlikely to mimic sounds, suggesting that song learning evolved with mechanisms to constrain learning to conspecific models.

This review critically examines the logic by which mimicry can be conceptually organized and analysed and highlights the following three evolutionarily relevant distinctions.

Mimicry, Camouflage and Perceptual Exploitation: the Evolution of Deception in Nature
  • E. Font

The common thread through these diverse phenomena is deception of a receiver by a mimic, and receiver deception emerges as a key characteristic of mimicry shared with some types of camouflage and perceptual exploitation.
Elaborate Mimetic Vocal Displays by Female Superb Lyrebirds
Detailed female vocal displays in a species widely depicted as an example of sexual selection for male extravagance are revealed and support the hypotheses that complex female vocalizations play a role in nest defense and mediate female-female competition for breeding territories.
Vocal mimicry in the song of Icterine warblers (Hippolais icterina): possible functions and sources of variability
The results suggest that Icterine warbler males largely reflect the surrounding acoustic environment in their song, but simultaneously selectively include vocalisations that are similar to their own song as a result of physiological constraints.
Hissing like a snake: bird hisses are similar to snake hisses and prompt similar anxiety behavior in a mammalian model
The acoustic similarity of the hissing sound produced by female blue tits, a cavity-nesting species, to the hisses of three snake species showed that snake and blue tit hisses are acoustically similar and provoke comparable anxiety behaviors in mice, compatible with the hypothesis that blue tits have evolved to mimic the sound of snakes.
The many functions of vocal learning
The diverse usages and proposed functions of learned novel signals are surveyed, to build a framework for considering the evolution of vocal learning capacities that extends beyond sexual selection.


Understanding Mimicry – with Special Reference to Vocal Mimicry
Convergently evolved model-mimic-resemblance, not essential in Batesian mimicry but mandatory for its alternatives, marks a fundamental distinction between Batesia mimicry (including Mimesis) and all other conceptualized mimicries and accounts for the non-existence of a unified meaning of the term mimicry.
Vocal mimicry and the evolution of bird song
Mimicry is normally suppressed by the need for specific identification but may emerge as a displacement activity where a species is exposed to predation or disturbance as a result of the need to make a loud and continuous noise and can be retained in song if it is biologically advantageous.
The function of vocal mimicry in some avian displays
Vocal mimicry in display is rare because specific identification is important. It occurs in the territorial displays of lyrebirds and bowerbirds and the reasons for this are examined. Its
How is model selection determined in a vocal mimic?: Tests of five hypotheses
This observational study of free-living northern mockingbirds suggests a potential non-adaptive explanation for the evolution of vocal mimicry because species that learn vocalisations are already predisposed toward learning sounds with key acoustic characteristics.
A comparative study of the function of heterospecific vocal mimicry in European passerines
It is found that effect sizes for intersong interval, brain size, breeding dispersal, abundance, age-dependent expression of repertoires, and predation risk reached a level that may indicate evolutionary importance.
The mimetic repertoire of the spotted bowerbird Ptilonorhynchus maculatus
It is suggested that enhanced learning capability during acute stress may explain vocal mimicry in many species that mimic sounds associated with alarm, and that it may be the alarming context in which these sounds are first heard that may lead both to their acquisition and to their later reproduction.
Context-dependent vocal mimicry in a passerine bird
How do birds select the sounds they mimic, and in what contexts do they use vocal mimicry? Some birds show a preference for mimicking other species' alarm notes, especially in situations when they
Acoustic mimicry in a predator–prey interaction
Visualizing bat–moth interactions with high-speed, infrared videography, empirical evidence for acoustic mimicry in the ultrasonic warning sounds that tiger moths produce in response to echolocating bats is provided.
Motor mechanisms of a vocal mimic: implications for birdsong production
It is shown that when a vocal mimic, the northern mockingbird, accurately copies the song of another species it also uses the vocal motor pattern employed by the model species, suggesting that species–specific acoustic features of the model seem most difficult to copy.
