The chestnut-winged cuckoo (Clamator coromandus) is a bird species known for its brood parasitism, laying eggs in the nests of other bird species. However, there is a paucity of genetic information available for this species and their genus Clamator. In this study, we present the first complete mitochondrial genome sequence of C. coromandus and compare it with other species within the Cuculidae family. The mitogenome is a closed circular molecule consisting of 17,082 bp with an organization typical of the mitochondrial genomes of Cuculidae. Alignment of the control regions across Cuculidae species revealed substantial genetic variation and a significant abundance of AT content. A significant difference was detected in AT-skews between brood-parasitic and parental-care species. A distinctive long poly-C sequence was located at the 5′ end of domain I. Phylogenetically, C. coromandus is more closely related to Piaya cayana than Ceuthmochares aereus. The phylogenetic analysis indicated a general divergence between species with brood parasitism and those with parental care, with transitions between these behaviors within brood parasitism branches, suggesting multiple evolutionary occurrences of these traits. The complete mitogenome of C. coromandus serves as a valuable resource for further investigation into the taxonomic status and phylogenetic history of Clamator species. Full article

There is very little information on the diurnal and seasonal patterns of Cuculidae species’ calling activity in subtropical areas. In this study, we used passive acoustic monitoring to investigate the diurnal and seasonal patterns of calling activity of seven Cuculidae species at three sites in eastern China’s forest over a year. Our results showed that these species exhibited significant diurnal variations except for Cuculus micropterus. Eudynamys scolopaceus and Cuculus saturatus increased their vocal activity at dawn and dusk, whereas the other four species peaked their calling activity in the morning. Five species showed significant seasonal variations with a peak in vocal activities earlier in the season (late May or early June) and a gradual decline after that, except for Clamator coromandus, which displayed two peaks in seasonal calling activity. As for Cuculus micropterus, its calling activity was not significantly related to the season. Our study has provided basic knowledge about the calling patterns of seven Cuculidae species, and based on seasonal changes in vocal activity we propose that the breeding season of these species in east China begins in late May and ends in July.
