“…In fact, in line with general predictions results were not found more often in passerine species than in other bird species. For instance, in New World doves (Tubaro & Mahler 1998), almost all acoustic variables were varying with the environment, contrary to general predictions. However, this might not be linked to the fact that these were nonpasserine birds, since no relationship between habitat features and acoustic structure (e.g., 40 South African passerine species : Hylton & Godard 2001) were also found in passerine species.…”

“…Moreover, the same negative correlation between body size and vocal pitch has also been found within species (e.g. Tubaro and Mahler 1998;Laiolo et al 2004;Koetz et al 2007;Geberzahn et al unpublished data). In addition to frequency parameters, call amplitude is thought to be an honest indicator of body size in insects and, thus, to play a crucial part in sexual selection in this taxon (Simmons 1988;Gray 1997).…”

Song amplitude and body size in birds

Bird song is a sexually selected multidimensional signal. A fundamental question regarding the evolution of sexually selected signals is what information they convey and how their honesty is maintained. Song amplitude is a performance-related signal trait that varies considerably between individuals, but this signal dimension has been neglected in past studies. I found that median song amplitude in male nightingales (Luscinia megarhynchos) and zebra finches (Taeniopygia guttata) did not vary significantly with body size or residual body mass. In contrast, I found a significant negative correlation between body size (and also residual mass) and the maximum song amplitude during interactive singing in nightingales. However, the function of these more subtle differences in song amplitude remains to be investigated. By and large, the results of this study suggest that mean song amplitude is unlikely to indicate a bird's body size or current condition (measured as residual mass).

In the context of sexual selection, animals have developed a variety of cues conveying information about the sex of an individual to conspecifics. In many colonial seabird species, where females and males are monomorphic and do not show obvious differences in external morphology, acoustic cues are an important signal for individual and sex recognition. Here, we study the vocal and morphological sex dimorphism in the King Penguin Aptenodytes patagonicus, a colonial, monomorphic seabird for which our knowledge about the role of vocalizations and morphology in mate choice is very limited. Data were collected at Possession Island, Crozet Archipelago, in a breeding colony consisting of about 16 000 breeding pairs. Using measurements of six morphological features and analysing acoustic parameters of call recordings of adult individuals, we show that King Penguins can be sexed based on a single morphological measurement of the beak with an accuracy of 79%. We found a sex‐specific syntax in adult King Penguin calls that provided a 100% accurate method to distinguish between the sexes in our study population. To confirm the method at the species level, we analysed calls recorded from King Penguin adults in Kerguelen Island, 1300 km away from our study population and found the same accuracy of the sex‐specific syntax. This sex‐specific syllable arrangement is rare in non‐passerines and is a first step in understanding the mate choice process in this species. Furthermore, it offers a cost‐effective, non‐invasive technique for researchers to sex King Penguins in the field.
