[FR] Nous rendons compte d’un cas de reproduction coopérative et paternité multiple putative dans un nid de Cossyphe à calotte blanche Cossypha albicapillus. Ces phénomènes n’ont pas jusqu’ici été rapportés pour cette espèce et les cossyphes proches. Dans un nid trouvé en Gambie, nous avons observé au moins cinq adultes de cette espèce nourrissant ou visitant les jeunes. Nous avons analysé le génome de quatre adultes (une femelle, trois mâles) et des deux jeunes en utilisant un marqueur microsatellite développé pour une autre espèce. Les données des génotypes étaient cohérentes avec l’hypothèse que la femelle était la mère des deux poussins, mais les allèles paternels suggéraient que deux mâles différents étaient les pères des poussins. Nos observations montrent qu’il peut y avoir une reproduction coopérative chez le Cossyphe à calotte blanche, et que cette espèce n’est pas toujours monogame comme on le supposait.
[EN] We report a case of cooperative breeding and putative multiple paternity in a nest of the White-crowned Robin-Chat Cossypha albicapillus. These phenomena have not been reported previously in this species and closely-related robin-chats. In a nest found in The Gambia we observed at least five adults feeding or visiting the young. We genotyped four adults (one female, three males) and the two young using a microsatellite marker previously developed for another species. The genotype data were consistent with the female being the mother of the two nestlings, but paternal alleles suggested two different males as fathers of the nestlings. Our observations show that cooperative breeding occurs in the White-crowned Robin-Chat, and that monogamy may not be as universal in this species as previously assumed.
The study was partially funded by a grant from the Royal Society of London to PJBS.
