“…First of all, male advertising call and female bubbling call are used in spacing behavior. In the breeding grounds, both males and females have home ranges of roughly similar sizes that are defended to some extent from same-sex rivals (Nakamura and Miyazawa 1997;Honza et al 2002;Vogl et al 2004;Nakamura et al 2005;Payne 2005;Erritzøe et al 2012;Williams et al 2016;Yun et al 2019). To repel same-sex rivals, males use advertising call (Moskát et al 2017(Moskát et al , 2018Tryjanowski et al 2018) while females emit bubbling call (Davies 2015;.…”

Background In the last decade, enigmatic male-like cuckoo calls have been reported several times in East Asia. These calls exhibited a combination of vocal traits of both Oriental Cuckoo (Cuculus optatus) and Common Cuckoo (Cuculus canorus) advertising calls, and some authors therefore suggested that the enigmatic calls were produced by either Common × Oriental Cuckoo male hybrids or Common Cuckoo males having a gene mutation. However, the exact identity of calling birds are still unknown. Methods We recorded previously unknown male-like calls from three captive Oriental Cuckoo females, and compared these calls with enigmatic vocalizations recorded in the wild as well as with advertising vocalizations of Common and Oriental Cuckoo males. To achieve this, we measured calls automatically. Besides, we video-recorded captive female emitting male-like calls, and compared these recordings with the YouTube recordings of calling males of both Common and Oriental Cuckoos to get insight into the mechanism of call production. Results The analysis showed that female male-like calls recorded in captivity were similar to enigmatic calls recorded in the wild. Therefore, Oriental Cuckoo females might produce the latter calls. Two features of these female calls appeared to be unusual among birds. First, females produced male-like calls at the time of spring and autumn migratory activity and on migration in the wild. Because of this, functional significance of this call remained puzzling. Secondly, the male-like female call unexpectedly combined features of both closed-mouth (closed beak and simultaneous inflation of the ‘throat sac’) and open-mouth (prominent harmonic spectrum and the maximum neck extension observed at the beginning of a sound) vocal behaviors. Conclusions The Cuculus vocalizations outside the reproductive season remain poorly understood. Here, we found for the first time that Oriental Cuckoo females can produce male-like calls in that time. Because of its rarity, this call might be an atavism. Indeed, female male-like vocalizations are still known in non-parasitic tropical and apparently more basal cuckoos only. Therefore, our findings may shed light on the evolution of vocal communication in avian brood parasites.

“…In general, territoriality, in response to increasing population density, may cause shrinkage in individual home ranges (Jirotkul 1999;Rothstein et al 1984). However, our previous study showed that the lesser cuckoo on Jeju Island share home ranges without antagonistic territorial interactions, which may allow them to extend their home ranges (Yun et al 2019). Further studies focusing on the factors affecting home range size will be worthwhile.…”

“…Confidence intervals not crossing zero represent statistically significant differences (p < 0.05) cowbirds (Molothrus ater) and common cuckoos (Cuculus canorus) commute daily between breeding and foraging sites, expanding the overall size of home ranges in these birds (approximately 1025 ha for the brown-headed cowbird, Rothstein et al 1984; 677 ha for the common cuckoo, Nakamura and Miyazawa 1997). However, a previous study has reported that the lesser cuckoo on Jeju Island display no commuting behavior, which is presumably due to the high degree of habitat heterogeneity (Yun et al 2019). Nevertheless, the size of their home ranges (315 ha) was relatively large when compared to those of other brood parasites that do not commute, such as shiny cowbirds (Molothrus bonariensis), screaming cowbirds (Molothrus rufoaxillaris), and Horsfield's bronze cuckoo (Chalcites basalis), which range from 27 to 170 ha (Langmore et al 2007;Scardamaglia and Reboreda 2014).…”

Background: Determining patterns of habitat use is key to understanding of animal ecology. Approximately 1% of bird species use brood parasitism for their breeding strategy, in which they exploit other species' (hosts) parental care by laying eggs in their nests. Brood parasitism may complicate the habitat requirement of brood parasites because they need habitats that support both their host and their own conditions for breeding. Brood parasitism, through changes in reproductive roles of sex or individual, may further diversify habitat use patterns among individuals. However, patterns of habitat use in avian brood parasites have rarely been characterized. In this study, we categorized the habitat preference of a population of brood parasitic lesser cuckoos (Cuculus poliocephalus) breeding on Jeju Island, Korea. By using compositional analyses together with radio-tracking and land cover data, we determined patterns of habitat use and their sexual and diurnal differences. Results: We found that the lesser cuckoo had a relatively large home range and its overall habitat composition (the second-order selection) was similar to those of the study area; open areas such as the field and grassland habitats accounted for 80% of the home range. Nonetheless, their habitat, comprised of 2.54 different habitats per hectare, could be characterized as a mosaic. We also found sexual differences in habitat composition and selection in the core-use area of home ranges (third-order selection). In particular, the forest habitat was preferentially utilized by females, while underutilized by males. However, there was no diurnal change in the pattern of habitat use. Both sexes preferred field habitats at the second-order selection. At the third-order selection, males preferred field habitats followed by grasslands and females preferred grasslands followed by forest habitats. Conclusions: We suggest that the field and grassland habitats represent the two most important areas for the lesser cuckoo on Jeju Island. Nevertheless, this study shows that habitat preference may differ between sexes, likely due to differences in sex roles, sex-based energy demands, and potential sexual conflict.
