Description
| - To study the use of space and habitat we radio-tagged 16 females of European cuckoos, Cuculus canorus. We hypothesized that during the laying period cuckoo females should (1) use habitats selectively, and (2) attempt to monopolize potential egg laying areas to reduce competition for host nests. Our data are consistent with the first hypothesis: the use of pond edges compared to forest and transitional habitats was significantly greater than expected from the habitat availability in the total area and within individual female home ranges. All 26 directly observed egg layings and 27 nest visits without laying occurred at pond edges in nests of Acrocephalus spp. Females spent significantly more time at pond edges on egg-laying days than on non-laying days. The second hypothesis was not supported: female home ranges overlapped similarly in all three major habitat categories of the potential egg laying areas, and only little aggression was observed between females.

- Ke studiu prostorového využití habitatů jsme radiotelemetricky označili 16 samic kukaček obecných. Předpokládali jsme, že během kladení těchto vajec samice by (1) měly habitat využívat selektivně a (2) měly by monopolizovat potencionální oblasti k parasitaci k omezení kompetice o hostitelská hnízda. Naše data jsou konsistentní s prvním předpokladem: využití okrajů rybníků v porovnání s ostatními biotopy bylo signifikantně významnější. Všech 24 přímo pozorovaných parasitických událostí a 27 návštěv bez parasitace se vyskytlo na okrajích rybníků ve hnízdech rákosníků (Acrocephalus). Samice kukaček se vyskytovaly signifikantně více na okrajích rybníků ve dnech, kdy parasitovaly hnízda, než ve dnech, kdy tato hnízda parasitována nebyla. Druhý předpoklad potvrzen nebyl: hnízdní okrsky se signifikantně překrývaly ve třech hlavních biotopech v potencionálních oblastech parasitace a pouze malá agresivita byla pozorována mezi samicemi.
