Do rufous common cuckoo females indeed mimic a predator? An experimental test

Popis výsledku v původním jazyce

The similarity of common cuckoos Cuculus canorus to raptors is accepted as a classic example of predator mimicry. However, cuckoo females are polymorphic: grey females are similar to sparrowhawks Accipiter nisus, while rufous females were assumed to mimic kestrels Falco tinnunculus. Previous evidence based on dummy experiments with grey females consistently showed that both hosts and non-hosts recognize this brood parasite by its yellow eye and barred underparts. However, these traits are absent in kestrels. Host responses also do not covary geographically with local abundance of supposed models (sparrowhawks/kestrels). These patterns cast doubts on the kestrel-mimicry hypothesis. Here, we show experimentally for the first time that small birds that are unsuitable as hosts indeed do not mistake rufous cuckoos for kestrels: both tree sparrows Passer montanus and house sparrows P. domesticus feared grey cuckoos (similarly to sparrowhawks and kestrels) but ignored rufous cuckoos (similarl
