Syntactic rules predict song type matching in a songbird
AbstractSong type matching has been hypothesized to be a graded signal of aggression; however, it is often the case that variation in matching...

Potential social facilitation through song in bird communities
AbstractThe main function of birdsong is to attract mates and defend territories among conspecifics, but little is known about the potential of this...

Bursts of white noise trigger song in domestic Canaries
Acoustic communication is fundamentally constrained by noise. In birds, the masking of mating signals (songs) may reduce fitness and, hence, they...

Song amplitude variation in Masked Gnatcatcher (Polioptila dumicola) as response to traffic noise
The vocal behavior of Neotropical birds has received less attention compared to birds in Northern temperate regions. Many bird species rely on...

Interspecific avoidance of song overlap in tropical songbirds: species-specific responses to acoustically similar and different intruders
AbstractTo ensure effective acoustic communication, signals should reach receivers in the least distorted form possible. Animals use various short-...

Hitting all the notes: Connecticut warblers sing an extended song type
Birds use songs to communicate with mates and rivals and thus these signals have important social and fitness consequences. Understanding the pattern...

Vocal behaviour of Sclater’s Wrens, a duetting Neotropical songbird: repertoires, dawn chorus variation, and song sharing
Diverse evolutionary forces have promoted the great diversity of vocal behaviour found in birds. The description of such behaviour is crucial for...

Neuroendocrine patterns underlying seasonal song and year-round territoriality in male black redstarts
BackgroundThe connection between testosterone and territoriality in free-living songbirds has been well studied in a reproductive context, but less...

The effect of variation in moonlight on nocturnal song of a diurnal bird species
AbstractThe lunar cycle is known to affect the behaviour of strictly nocturnal species, but for diurnal species that are periodically active during...

Song-type switching rate in the chaffinch carries a message during simulated intrusion
AbstractBirds communicate their motivation and willingness to escalate a territorial conflict with a variety of agonistic signals. One of these,...

Vermilion flycatchers avoid singing during sudden peaks of anthropogenic noise
In many animals, vocalizations are necessary for social interactions to occur; however, anthropic noise can pose a problem as it can disrupt acoustic...

Does learning matter? Birdsong-learning program determines co** strategies for living in urban noisy environments
AbstractUrban noise limits perception by masking acoustic signals, with negative consequences for communication. Although animals relying on acoustic...

Birdsong Overlap**: Random Coincidence or Acoustic Interactions
AbstractBirdsong overlap** may either indicate communicative interaction between birds or be a simple coincidence. We developed a program that...

Do the rain calls of Chaffinches indicate rain?
For more than 300 years, the rain call of the Common Chaffinch ( Fringilla coelebs ) has been thought to herald rain—hence the name. However, the...

Start of dawn singing as related to physical environmental variables in an alpine environment
Birds often have a peak of singing activity at dawn, and the timing of dawn song is species-specific. However, the start of singing at dawn may also...

Constraints on song type matching in a songbird
AbstractIn an eastern population of song sparrows ( Melospiza melodia ), song type matching occurs at above chance levels but does not signal...

A well-studied parasitoid fly of field crickets uses multiple alternative hosts in its introduced range
Organisms and their natural enemies can have dynamic coevolutionary trajectories, but anthropogenic effects like species introductions interrupt...

Heterospecific eavesdrop** of jays (Garrulus glandarius) on blackbird (Turdus merula) mobbing calls
Heterospecifics eavesdrop on mobbing calls and respond with appropriate behavior, but the functional aspects are less studied. Here, I studied...

Technogenic Noise Affects the Minimum Frequency of Chaffinch Song Components (Fringilla coelebs) in the Moscow Population
AbstractTo test the hypothesis that birds shift song parameters to higher frequencies in response to continuous low-frequency noise, we received...

The Yellow-breasted Barbet (Trachyphonus margaritatus) introduces vocal duets and choruses with a specific multimodal signal, during territorial advertisement
Cooperative behaviour is a prominent feature among many group-living species and continues to pose challenges to our understanding about the...
