A number of studies of common cuckoos . in Europe and Asia have shown that cuckoos are particularly successful s

https://doi.org/10.1007/978-1-4612-2758-8 help feed young that are not their offspring, whereas brood parasites exploit the parental behaviour of a host, thus avoiding the costs of raising their progeny. Recent evidence, however, uncovered an evolutionary link between the two systems. On the one hand, it has been shown theoretically and em

Brood Parasitism in Birds: A Coevolutionary Point of View,predictions of coevolutionary theory. Next I describe the current situation of coevolution in brood parasite–host systems emphasizing three points that should be taken into account in studies centred on this subject. Later, I suggest three potentially important topics that have been almost neglected

Factors Affecting the Rates of Coevolution Between Obligate Avian Brood Parasites and Their Hosts of coevolution in bird populations empirically and mention current studies that are resolving this problem by focusing on recently parasitized host populations. Understanding how rapidly hosts can evolve defenses to circumvent brood parasitism is an important step in uncovering aspects of speciatio

A Taxonomic Review of Obligate and Facultative Interspecific Avian Brood Parasitismdiscussed. Since obligate brood parasitism is shown to be a very effective way of increasing the individual’s fecundity, the reasons for only about 1% of bird species evolving this strategy are discussed.
