“…4a; also Martin et al 2013). Other lowland temperate and subtropical members of its family did not show such behavior (Tasinazzo 1993, Kawaji et al 1996, Hamao and Hayama 2015, Bi et al 2020). The long off-bout caused eggs to drop to very cool ambient temperatures (15-20°C) and remain there for several hours and caused relatively cool mean egg temperatures (Martin et al 2013).…”

“…Even though stubtail nestlings developed relatively quickly, they showed some of the lowest rates of adult provisioning among the Cettiidae species that we explored (see Kawaji et al 1996, Hamao and Hayama 2015, Bi et al 2020). In a high-predation environment, the benefits of such low provisioning rates may be twofold: less frequent visits to the nest by adults can prevent predators from detecting the nest, and the resulting prolonged nestling period can provide extra time for nestlings to develop the traits they need in order to survive upon fledging (Martin 2014, Martin et al 2018).…”

“…The typical nest site of cuckoos' major host species, the Japanese bush warbler utilized in our study area, was characterized by trees and shrubs such as the Japanese holly (Ilex crenata) and the arrow bamboo (Pseudosasa japonica). These potential nest sites were mostly distributed along the boundaries of the various habitats described above (Hamao 2014;Hamao and Hayama 2015).…”

Habitat selection in the lesser cuckoo, an avian brood parasite breeding on Jeju Island, Korea

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.

Patterns of vocal activity may involve information about vocalizations themselves as well as their function. In birds, vocal activity at the individual and population level is generally closely associated with breeding cycles, reaching the peak during territorial and mating competition, and decreasing with the onset of egg incubation and chick feeding. However, little is known about patterns of vocal activity in avian brood parasites that have unusual breeding cycles without parental care. Using passive acoustic monitoring, we determined the seasonal and diurnal patterns of population vocal activity in two avian brood parasites: the Common Cuckoo Cuculus canorus and the Lesser Cuckoo C. poliocephalus. We found that both species and both sexes showed a similarly highly structured pattern of seasonal vocal activity, reaching a sharp peak in the early breeding season when birds compete for territories and mates, although males sang more frequently than females. Likewise, the diurnal patterns of vocal activity were similar in both species and both sexes of cuckoos, with peak activity occurring around dawn. Nocturnal calls by male cuckoos were also detected in both species, but only in the early breeding season. Collectively, the observed patterns of population vocal activity may suggest that the absence of parental care may not extend the period of vocal activity in these two species of brood parasites.
