Lazy males and hardworking females? Sexual conflict over parental care in a brood parasite host and its consequences for chick growth

Popis výsledku v původním jazyce

Due to the costs of parental care, a conflict of interests often arises between mates wherein each prefers the other to invest more. As with parents raising their own offspring, hosts of brood parasites also exhibit negotiations over investment, becomingparticularly intensive when parasite demands are high. Lack of cooperation between the partners may eventually affect the condition and fledging success of the young. Here, we investigate the magnitude of sexual conflict over food provisioning in socially polygynous great reed warblers (Acrocephalus arundinaceus) rearing either a parasitic common cuckoo (Cuculus canorus) or their own nestlings and its consequences for chick growth. We found that, overall, males provided less food than females, and thatpolygynous males provided less food per nest than monogamous males. Moreover, polygynous males provisioning two simultaneous broods supplied their own offspring in relation to age and type (cuckoo/host) of the other brood. Females, unlik
