Description
| - Testovali jsme rozpoznávání dvou barevných morf kukačky obecné rákosníkem velkým ve dvou oblastech s různou mírou hnízdního parazitismu a odlišnými poměry barevných morf. Hostitelé rozpoznávali obě morfy od kontrolního druhu v Apaji (kde je míra hnízdního parazitismu vysoká), ale ne v Lužicích (kde je míra parazitismu nízká). V Apaji hostitelé rozpoznávali lépe hnědou morfu (která je zde početnější) než šedou. Srovnání mezi lokalitami ukázalo, že rákosníci velcí byli agresivnější k hnědé morfě v Apaji než v Lužicích, zatímco jejich reakce na šedou morfu se nelišila, což odpovídá mnohem většímu rozdílu v relativní početnosti hnědé morfy na sledovaných lokalitách. Naše výsledky naznačují, že obranu hnízda hostitele významně ovlivňuje jak míra parazitismu, tak zastoupení barevných morf hnízdního parazita. (cs)
- 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 brood parasitism 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 gray morph 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-site difference 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.
