Host density predicts presence of cuckoo parasitism in reed warblers

Popis výsledku v původním jazyce

We investigated possible predictors of common cuckoo Cuculus canorus parasitism in 16 populations of reed warblers Acrocephalus scirpaceus across Europe. We quantified the effect of host density, number of host breeding pairs, habitat type, mean distanceto nearest cuckoo vantage point, predation rate and latitude on the presence of cuckoo parasitism while controlling for geographical distance among study populations. Host density was a powerful predictor of parasitism. We also found a less pronounced effect of habitat type on occurrence of parasitism, while the other variables did not explain why cuckoos utilize some reed warbler populations and not others. This is the first study focusing on patterns of common cuckoo-host interactions within a specific host species on a large geographic scale. The results indicate that if host density is below a specific threshold, cuckoo parasitism is absent regardless of the state of other potentially confounding variables.
