Název v původním jazyce

Host nest defense against a color-dimorphic brood parasite: great reed warblers (Acrocephalus arundinaceus) versus common cuckoos (Cuculus canorus)

Popis výsledku v původním jazyce

We tested great reed warbler discrimination against two common cuckoo female color morphs in two areas with different parasitism rates and proportions of the two morphs. Hosts recognized the two cuckoo morphs from a control at Apaj, Hungary (where broodparasitism was heavy), whereas no significant differences among the models were recorded at Lužice, CZ (where the parasitism rate was moderate). At Apaj, the hosts discriminated the rufous morph (which is slightly predominant there) better than the graymorph from the control. Between-site comparison revealed that great reed warblers were more aggressive towards the rufous morph at Apaj than at Lužice, whereas their responses to the gray morph did not differ, corresponding with much higher between-sitedifference in the relative abundance of the rufous morph. Our results suggest that both local parasitism pressure and relative abundance of two female color morphs of a brood parasite may significantly influence host nest defenses.
