Experimental evidence for chick discrimination without recognition in a brood parasite host

Original language description

Recognition is considered a critical basis for discriminatory behaviours in animals. Theoretically, recognition and discrimination of parasitic chicks are not predicted to evolve in hosts of brood parasitic birds that evict nest-mates. Yet, an earlier study showed that host reed warblers (Acrocephalus scirpaceus) of an evicting parasite, the common cuckoo (Cuculus canorus), can avoid the costs of prolonged care for unrelated young by deserting the cuckoo chick before it fledges. Desertion was not basedon specific recognition of the parasite because hosts accept any chick cross-fostered into their nests. Thus, the mechanism of this adaptive host response remains enigmatic. Here, I show experimentally that the cue triggering this ?discrimination withoutrecognition? behaviour is the duration of parental care. Neither the intensity of brood care nor the presence of a single-chick in the nest could explain desertions. Hosts responded similarly to foreign chicks, whether heterospecific or

Experimentální důkaz pro diskriminaci bez rozpoznávání u hostitele hnízdního parazita

Czech description

Práce experimentálně ukazuje, že hostitel kukačky (rákosník obecný) dokáže odmítnout parazitické mládě aniž by jej rozpoznal jako takové. Mechanismem odmítnutí je délka rodičovské péče na hnízdě (u kukačky výzhnamně delší než u hostitele).
