“…This call is typically given from the vegetation 2-10 m above the bower and hence would not be subject to potential ground attenuation effects (see Price, Attenborough & Heap 1988). Variation in this advertisement call has been described among three south-eastern Queensland populations (Tack et al . 2005).…”

“…It also allows an examination of the effect of habitat type at multiple geographical scales, as changes in its habitat occur both at large scales (in the order of several hundred kilometres) and at very local scales (< 10 km). Male satin bowerbirds construct a stick bower on the ground, which acts as the focal point of their display and the primary cue for female mate choice, and they give a loud call to advertise the presence of this bower (Borgia 1985; Tack et al . 2005).…”

Summary1. This study provided a thorough test of the acoustic adaptation hypothesis using a within-species comparison of call structure involving a wide range of habitat types, an objective measure of habitat density and direct measures of habitat-related attenuation. 2. The structure of the bower advertisement call of the satin bowerbird was measured in 16 populations from throughout the species' range and related to the habitat type and density at each site. Transmission of white noise, pure tones and different bowerbird dialects was measured in five of six habitat types inhabited by satin bowerbirds. 3. Bowerbird advertisement call structure converged in similar habitats but diverged among different habitats; this pattern was apparent at both continent-wide and local geographical scales. Bowerbirds' call structures differed with changes in habitat density, consistent with the acoustic adaptation hypothesis. Lower frequencies and less frequency modulation were utilized in denser habitats such as rainforest and higher frequencies and more frequency modulation were used in the more open eucalypt-dominated habitats. 4. The white noise and pure tone transmission measurements indicated that different habitats varied in their sound transmission properties in a manner consistent with the observed variation in satin bowerbird vocalizations. 5. There was no effect of geographical proximity of recording locations, nor was there the predicted inverse relationship between frequency and body size. 6. These findings indicate that the transmission qualities of different habitats have had a major influence on variation in vocal phenotypes in this species. In addition, previously published molecular data for this species suggest that there is no effect of genetic relatedness on call similarity among satin bowerbird populations.

“…Songs were recorded using a Sennheiser ME67 microphone with K6 power supply, digitized at a sampling rate of 44.1 kHz and recorded uncompressed directly to hard disk using an iRiver iHP-140 hard disk recorder. For one site (B), additional recordings of bowerbirds from a previous study (Tack et al 2005) were also used.…”

“…We recorded the advertisement songs of male satin bowerbirds and mimicry of this song by male Albert's lyrebirds at each of six sites in southeast Queensland (1538E, 288S), Australia, during 2004 and2005. Sites were located at Binna Burra (A), Green Mountains (B), Springbrook (C), Tamborine Mountain (D), Gambubal (E) and Goomburra (F) (figure 1). Individuals of both species can be reliably located at known territories or regular display sites.…”

“…Many of the model species whose songs are incorporated into the lyrebird display show geographical variation in song structure. For example, the advertisement song of the satin bowerbird (Ptilonorhynchus violaceus) is known to vary in structure among populations throughout its range along the east coast of Australia (Tack et al 2005;Nicholls & Goldizen 2006), and is a common feature in lyrebird mimicry.…”

Imitating the neighbours: vocal dialect matching in a mimic–model system

Vocal mimicry provides a unique system for investigating song learning and cultural evolution in birds. Male lyrebirds produce complex vocal displays that include extensive and accurate mimicry of many other bird species. We recorded and analysed the songs of the Albert's lyrebird (Menura alberti ) and its most commonly imitated model species, the satin bowerbird (Ptilonorhynchus violaceus), at six sites in southeast Queensland, Australia. We show that each population of lyrebirds faithfully reproduces the song of the local population of bowerbirds. Within a population, lyrebirds show less variation in song structure than the available variation in the songs of the models. These results provide the first quantitative evidence for dialect matching in the songs of two species that have no direct ecological relationship.
