“…), utilize a song that, although stereotyped, is important during the breeding season (Kroodsma & Miller, ). Call features always served as an important basis for interspecies classification in different cuckoo species (Kim, Lee, & Yoo, ; Xia, Liang, Carey, & Zhang, ). Although it is tacitly assumed that cuckoo vocalizations during the breeding season serve as a means of mate attraction (King, ; Xia et al, ), this crucial assumption remains untested empirically.…”

The function of three main call types in common cuckoo

Acoustic signals play a key role in shaping the relationships in birds. Common cuckoos Cuculus canorus are known to produce various call types, but the function of these calls has only been studied recently. Here, we used a combination of field recordings (conducted in 2017) and playback experiments (conducted in 2018) to investigate the functional significance of common cuckoo calls. We found significant differences in the characteristics between male two‐element “cu‐coo” and three‐element “cu‐cu‐coo” calls, with these two call types being used in different contexts. The three‐element male “cu‐cu‐coo” calls were associated with females emitting their “bubbling” call. Playback experiments revealed that both males and females exhibit stronger responses to playing female “bubbling” calls than with the calls of the Eurasian sparrowhawk (Accipter nisus) serving as a control, suggesting a significant intraspecific communication function for this call type. However, we did not find any evidence to support mate attraction in male calls, as females were not stimulated by playback of male calls compared with sparrowhawk calls in the control group.

“…Such a function would enable female cuckoos to benefit from reducing their egg rejection rate through distraction of the attention of hosts (York and Davies, 2017). Other aspects of female cuckoo calls remain unquantified in the peer-review literature (Liang, 2017;Kim et al, 2017).…”

Investigations on bird vocalizations have largely focused on males. Female vocalizations are widespread in birds but few studies have investigated female vocal characteristics, particularly in non-Passeriformes. In this study, we use new field recordings from China, and calls available from an online sound library to examine temporal patterns, call consistency and geographical variation in vocalizations of female common cuckoos Cuculus canorous. The peak in vocal activity (both male and female) was in the morning, which contrasts to what would be predicted if the sole function of the female call was to distract the attention of hosts after parasitizing a host's nest in the afternoon. Both male and female common cuckoos were more vocally active in sunny weather, than rainy weather. We also found larger intra-individual variation in female rather than in male calls, which may benefit female cuckoos by increasing stimulation to host species. Peak frequency of female calls decreased with increased latitude, while differences in female call features were not associated with geographic distance. In summary, our findings that female calls are used in the morning, rather than at peak egg laying, yet are highly variable and show little geographic patterns suggest that the function of these female calls may be more variable and intricate than previously thought. However, because research on female vocalizations is underrepresented, future studies are still needed.

“…Some brood parasites also have thicker eggshells ( Brooker and Brooker 1991 ), which can protect the parasitic egg from damage by hosts or other parasites. It has also been found that parasitic cuckoos have less complex and lower frequency vocalizations, which might travel better through their large breeding rages ( Kim et al. 2017 ).…”

From micro- to macroevolution: brood parasitism as a driver of phenotypic diversity in birds

Abstract A fundamental question in biology is how diversity evolves and why some clades are more diverse than others. Phenotypic diversity has often been shown to result from morphological adaptation to different habitats. The role of behavioural interactions as a driver of broad scale phenotypic diversity has received comparatively less attention. Behavioural interactions, however, are a key agent of natural selection. Antagonistic behavioural interactions with predators or with parasites can have significant fitness consequences, and hence act as strong evolutionary forces on the phenotype of species, ultimately generating diversity between species of both victims and exploiters. Avian obligate brood parasites lay their eggs in the nests of other species, their hosts, and this behavioural interaction between hosts and parasites is often considered one of the best examples of coevolution in the natural world. In this review we use the coevolution between brood parasites and their hosts to illustrate the potential of behavioural interactions to drive evolution of phenotypic diversity at different taxonomic scales. We provide a bridge between behavioural ecology and macroevolution by describing how this interaction has increased avian phenotypic diversity not only in the brood parasitic clades but also in their hosts.
