Abstract Neighbouring territorial songbirds often interact through countersinging, where birds sing in response to the singing of neighbours such that their song bouts are temporally related. Complex forms of countersinging such as song type matching or song overlapping appear to be correlated with aggressiveness and readiness to escalate confrontations. Less attention has been paid to the importance of simpler forms of countersinging, where matched song types are not used and where individual…

Song as an aggressive signal in songbirds

Aggressive responses to broadband trills are related to subsequent pairing success in nightingales

The results indicate that rapid broadband trills are a signal of aggression and that the nature of the response in vocal interactions reflects aspects of the challenged male's fitness.

Vocalization as an indicator of individual quality in the rock hyrax

The purpose of this research was to investigate the relationships between male hyrax songs and individual attributes, such as survival, body condition, hormonal state and social status, and found that females had similar levels as males of both androgens tested, which is a first of its kind.

Constrained Performance in a Communication Network: Implications for the Function of Song‐Type Matching and for the Evolution of Multiple Ornaments

It is hypothesized that higher‐performance singers benefit from matching their opponent’s song type because matching improves eavesdroppers’ ability to compare the two males’ performances, and speculated that lower‐performance individuals might have driven the evolution of repertoire complexity because they stand to benefit from novel, unmatchable songs.

A test of the dear enemy hypothesis in female New Zealand bellbirds (Anthornis melanura): female neighbors as threats

Clear evidence is found that individual females discriminate between conspecific female neighbor and stranger song, and it is predicted that higher levels of aggression may play a role in sexual selection and polygny prevention and that neighboring females are the greatest threat to the loss of a mate.

Intra- and Intersexual Functions of Singing by Male Blue Grosbeaks: the Role of Within-Song Variation

Within-song variation may be an important way to vary song meaning for male Blue Grosbeaks, and perhaps other males in species with a single song type but repertoires of several different song elements.

Social status and cortisol levels in singing rock hyraxes

Vocal behaviour and neighbour spatial arrangement during vocal displays in eagle owls (Bubo bubo)

Analyses of the characteristics of call posts showed that the choice of such focal points was guided by the trade-off between the need to defend the territory and within-pair communication inside the core areas, as well as efficient communication with neighbours.



Nightingales respond more strongly to vocal leaders of simulated dyadic interactions

Although vocal interactions in songbirds have been well studied, little is known about the extent to which birds attend to their conspecifics' interactions. Attending to others' interactions can

Effects of dyadic vocal interactions on other conspecific receivers in nightingales

Testing whether asymmetric interactions, in which one bird overlaps the song of another individual, influences the behaviour of additional, passive conspecific receivers, suggests that, even if song overlapping is a signal directed towards the singer whose song is overlapped, this information is perceived and used by additional receivers.

The signal function of overlapping singing in male robins

Playback was used to study the information contained in such timing of song exchanges in territorial male robins, Erithacus rubecula, consistent with the idea that interacting with a singer either by overlapping or alternating is a way of indicating the intended receiver whereas non-interactive (loop) playback does not give this information.

Songbird cheaters pay a retaliation cost: evidence for auditory conventional signals

This system will punish and prevent cheaters, as weak males signalling aggression will be subject to escalation by stronger or more–motivated opponents, and repertoire matches induce faster approach than do unshared song types.

Is song–type matching a conventional signal of aggressive intentions?

The results and consideration of alternatives suggest that type matching in song sparrows is a conventional signal in which honesty is maintained by a receiver retaliation cost against bluffers.

The role of distance, familiarity, and time of day in Carolina wrens responses to conspecific songs

Carolina wrens discriminate significantly between songs played from outside to those played inside their territories only if they are familliar with the song type played, and responded stronger to unfamiliar than to familiar songs when these were played fromoutside the territory.

Repertoire matching between neighbouring song sparrows

A male song sparrow,Melospiza melodia, has a song repertoire of about eight or nine distinct song types, and he typically shares several of these song types with each of his several neighbours. In

Song-type matching between neighbouring song sparrows

The hypothesis that type matching is a threat or warning signal is considered and the specific prediction that a bird is more likely to type-match early in the breeding season when territory boundaries are new and still unstable, and more likelihood to repertoire-match later in the season, once those boundaries have become well established is tested.

Do female great tits (Parus major) assess males by eavesdropping? A field study using interactive song playback

Although the absolute song output of males did not differ between treatments, males produced more song relative to playback in de–escalation treatments and relative song output was positively correlated with female intrusions, suggesting female great tits eavesdrop on singing interactions and change their visitation rates to neighbouring territories according to their mate's singing performance relative to neighbours.
