Behaviour of African turdid hosts towards experimental parasitism with artificial red-chested cuckoo Cuculus solitarius eggs

Original language description

The red-chested cuckoo parasitises many passerines in Africa. The kurrichane thrush, which is not regularly parasitized by the cuckoo, rejected 60% of mimetic model eggs and 81% of non-mimetic eggs. We observed female thrush behaviour during the first visit after parasitism, and thrushes appeared to be initially fooled by mimetic eggs in completed clutches in all cases, and incubated. By contrast, in half of the experiments with non-mimetic eggs, these were ejected by the thrushes, with the host grasping the egg and flying away with it. The time spent nest checking prior to ejection was only one third of the time spent nest checking when females decided to incubate the clutch, suggesting that females were immediately aware of a foreign egg in the nest.By contrast, southern olive thrushes rejected all non-mimetic and accepted all mimetic model eggs, whereas cape robins accepted all model eggs, irrespective of whether or not they were mimetic.

Czech description

Cuculus solitarius parasituje mnoho pěvců v Africe. Turdus libonyana, který není parasitován odmítal 60% mimetických a 81% nemimetických vajec. Turdus olivaceus odmítal nemimetická a akceptoval mimetická vejce, zatímco Cossypha caffra akceptoval všechnytypy vajec. Tyto výsledky byly diskutovány v souvislosti ?arms race hypothesis?.
