Differences in behaviour of closely related thrushes (Turdus philomelos and T. merula) to experimental parasitism by the common cuckoo Cuculus canorus.

Popis výsledku v původním jazyce

The common cuckoo Cuculus canorus parasitizes many passerines, but some common species sympatric with the brood parasite are rarely used as hosts. Potential host species may escape brood parasitism using methods such as high rejection of cuckoo eggs or high aggressiveness towards female parasite. We tested the responses of two common species, the song thrush Turdus philomelos and blackbird T. merula, not regularly parasitised by the cuckoo, to artificial cuckoo eggs and dummies. Both species rejected model parasitic eggs (song thrush 58.3%, blackbird 66.7%). Song thrushes showed very low levels of aggression toward a stuffed dummy, while blackbirds were very aggressive. Neither species discriminated between the cuckoo and control pigeon dummies. We observed one case of intraspecific nest parasitism in the song thrush. This is probably the first documentation of intraspecific nest parasitism in this species. Both our and previously published data indicate that the rejection behaviour of
