Cuckoo growth performance in parasitized and unused hosts: not only host size matters

Popis výsledku v původním jazyce

The quality and quantity of food delivered to young are among the major determinants of fitness. A parental provisioning capacity is known to increase with body size. Therefore, brood parasitism provides an opportunity to test the effects of varying provisioning abilities of different sized hosts on parasitic chick growth and fledging success. Knowledge of growth patterns of common cuckoo, Cuculus canorus, chicks in nests of common hosts is very poor. Moreover, no study to date has focused on any currently unused hosts (i.e. suitable cuckoo host species in which parasitism is currently rare or absent). Here, I compare growth performance of cuckoo chicks in nests of a common host (the reed warbler, Acrocephalus scirpaceus) and two unparasitized hosts (the song thrush, T. philomelos, and the blackbird, Turdus merula). Parasitic chicks were sole occupants of observed nests, thus eliminating the confounding effect of competition with host chicks. Experiments revealed striking differences i
