“…Because we were testing for cultural transmission, we included males that defended a nest box within 100 m of the focal nest. This distance ensured that songs would not suffer a significant sound degradation within the nest box for nestlings to be able to hear the neighbor songs, if he sang (see Lampe et al, 2004, 2007), and eventually, to learn some syllables. Because of this distance restriction, we only included 15 male neighbors.…”

Singing is a key element of songbirds’ behavioral repertoire, particularly for males, which sing during the breeding season to defend resources against other males and to attract females. Different song traits may convey honest information about males’ qualities or conditions, which may be used by females to select their mates. Traits under strong sexual selection have an important component of additive genetic variation (i.e., the main genetic inheritance from parents), and so relatively high heritability; therefore, it can be expected that song traits also do. Although the act of singing is an innate behavior, and thus, genetically determined, songbirds need to learn their songs and therefore the genetic contribution to song traits may be reduced by the effect of environmental factors. We tested this hypothesis in seven song traits recorded in the long-distance migratory bird, the pied flycatcher (Ficedula hypoleuca). From a 23-year database (1992–2015), we obtained songs for 28 father–son pairs, and for each song trait we applied parent–offspring regressions to estimate heritability. The type of syllables sung are learned from tutors, and here we also determined the cultural contribution of fathers to the song repertoires of their sons, by quantifying the percentage of syllables that sons shared with their fathers, and compared this with what sons shared with other males in the population (e.g., neighbors). The heritabilities of song traits were highly variable (ranging from −0.22 to 0.56), but most of these were around zero and none of them were significant. These results indicate that the seven song traits are most likely determined by environmental factors. Sons shared more syllables with their fathers than with neighbors (21% vs. 3%), suggesting that fathers are important song tutors during the nestling period. We conclude that there is a cultural inheritance from fathers to their sons’ syllable repertoires, but there is no strong evidence for a genetic contribution of fathers to the seven song traits studied.

“…Enclosed nests are expected to buffer any noises coming from inside and thereby reduce the detectability of nests due to auditory cues (Lampe et al, ; Magrath et al, ). Indeed, we found the bandwidth of sounds emanating from enclosed nests was often reduced compared to open nests in both the laboratory and field which is thought to reduce their detectability by predators (Figure ; Magrath et al, ).…”

“…While eggs and young may be concealed in enclosed nests, the addition of a roof and walls may also result in larger nest size which can increase the likelihood that visually oriented predators detect the nest (Biancucci & Martin, ; Møller, ; Snow, ). Moreover, sound from nestling begging is thought to influence predation risk and the roof and walls of enclosed nests might alter the sound of begging young which could influence the likelihood it is detected by predators (Briskie, Martin, & Martin, ; Haff & Magrath, ; Haskell, ; Lampe, Dabelsteen, Larsen, & Pedersen, ; Leech & Leonard, ; Magrath, Haff, Horn, & Leonard, ; Mennill & Ratcliffe, ). For example, if sound waves travelling through nest walls are reduced in volume and bandwidth or increased in frequency, they should be less detectable or localizable by predators (reviewed in Magrath et al, ).…”

Offspring mortality varies dramatically among species with critical demographic and evolutionary ramifications, yet the causes of this variation remain unclear. Nests are widely used for breeding across taxa and thought to influence offspring mortality risk. Traditionally, more complex, enclosed nest structures are thought to reduce offspring predation by reducing the visibility of nest contents and muffling offspring sounds compared to open nests. Direct tests of the functional bases for nest structure influence on predation risk are lacking. We used experiments and 10 years of observational data to examine how nest structure influences nest predation risk in a diverse community of tropical songbirds. First, we examined how nest size was related to nest structure and nest predation rates across species. Second, we assessed how nest structure influences the detectability of nestling begging calls both in field and in laboratory settings. Finally, we examined how the acoustic properties of different nest structures influence nest predation risk. Specifically, we experimentally broadcast begging calls from open and enclosed nests to determine how auditory cues and nest structure interact to affect predation on plasticine and quail eggs. We also tested whether nest structure was associated with differences in nest predation rates between the incubation (no begging cues) and nestling (begging cues) stages. We found that enclosed nests are larger than open nests after accounting for adult size, and larger nests had increased predation rates. Moreover, enclosed nests did not consistently alter nestling begging calls in ways that reduce the likelihood of predation compared to open nests. Indeed, begging cues increased predation rates for enclosed but not open‐cup nests in our playback experiment, and nest predation rates showed greater increases after hatching in enclosed than open‐cup nests. Ultimately, enclosed nests do not necessarily provide greater predation benefits than open nests in contrast to long‐standing theory.

“…The importance of FM in wood ducks is intriguing because of a potential problem having to do with the nesting ecology of the species. Specifically, nest cavities can alter acoustic features of sounds due to the resonating properties of the cavities (e.g., Lampe, Dabelsteen, Larsen, & Pedersen, 2004). Even though wood duck hens utter notes from outside the box that have slightly exaggerated descending FMs, there is a possibility that this acoustic feature is altered or obscured when the sound transmits through the opening of the cavity (or box) and reaches the ducklings deep inside on the nest substrate.…”

Gilbert Gottlieb's developmental theory views organismic development as a multilevel system involving ongoing transactions among different levels of organization. Here, I review his conception of development as it has been influenced historically and has guided several lines of empirical inquiry focusing on auditory communication in birds. Ecological factors are considered an important means of identifying possible nonlinear (i.e., subtle or nonobvious) forms of experience that play a significant role in species-typical development. Failure to consider such nonlinearities, along with obvious linear influences, undermines the developmental point of view that Gottlieb advocated as a means of teasing apart the intricate nature of organismic development. ß 2007 Wiley Periodicals, Inc.
