First evidence that is emerging is that some Common Cuckoo gentes also have host-specific nestling communication strategies Davies et al. Multiple effects of brood parasitism reduce the reproductive success of prothonotary warblers, Protonotaria citrea.

Such non-randomness has been documented for nest sites of hosts: Fitness costs and benefits of cowbird egg ejection by gray catbirds. cowbirde

Parentage without parental care: Go to Conservation Land Management. Trine C, Robinson W. Common cuckoos Cuculus canorus lay eggs with larger yolk but not more testosterone than their great reed warbler Acrocephalus arundinaceus hosts.

Habitat and space use of European cuckoo females during the egg laying period. Other books in the series. Break-down of arms race between the red-backed shrike Lanius collurio and common cuckoo Cuculus canorus Behaviour. How precise is egg discrimination in weaverbirds? The young cuckoo flashes these yellow skin patches at the host parent otger stimulate feeding, and indeed host parents sometimes try to feed the wing patch.

Cuckoos, Cowbirds and Other Cheats

If parents were using the amount of parental care required as a discriminating mechanism, no learning or imprinting would need to be invoked. Coevolution of an avian host and its parasitic cuckoo. For example, the Common Cuckoo—Reed Warbler system shows dynamic behaviour at least in one location.


Browse titles from Poyser. Molecular phylogeny of cuckoos supports a polyphyletic orgin of brood parasitism. The presumed ancestral state is shaded in light grey, whereas the common current state in parasitic cuckoos is cuckos boldly lined box. Please review our privacy policy.

Brood parasites fill their armory with adaptations including exquisite These species build domed nests and the dark environment might preclude egg colouration from being a reliable clue. Given that both egg rejection and acceptance have costs and benefits, an optimality approach can be applied to work out a threshold frequency of brood parasitism above which egg rejection results in higher reproductive success and below which egg acceptance is favoured.

However, brood parasites share common ground with their hosts in that they benefit if the nest is not found by a predator after they have laid an egg. This aggressive behaviour can be a specific response to parasitism: Potential future directions for research might include genetic studies of the mating system and on sexual conflict between the sexes, a more comprehensive approach to understand the non-randomness of brood parasitism and the nonlinear costs of brood parasitism during the lifetime of a host individual, and further experimental work on the fitness costs of brood parasitism and the interactions between parasite chick, host chicks and host parents in non-ejecting species.

Click to have a closer look. Benton Richard Fortey View All. Hosts, meanwhile, have evolved larger inter-clutch variation but smaller intra-clutch variation Stokke et al. Conclusions Brood parasitism and host responses continue to attract a disproportional interest from researchers because the avian parasite—host system is not only one of the best models for the coevolutionary process, but is also uniquely tractable and open to experimental manipulation.

Sinauer Associates; Sunderland, MA: Host use and fecundity of individual female brown-headed cowbirds. He has travelled widely and broadcasts frequently in both Welsh and English.

A previously unknown adaptation in a cuckoo chick comes from a study of the Horsfield’s Hawk-cuckoo Hierococcyx hyperythrus in Japan. These questions have been tackled in comparative analyses. If parasitized, the defence mechanism would be ineffective but there would not be other costs.


Brood parasitism by the cuckoo on patchy reed warbler populations in Britain. He has seven previous books to his name. He knew that species closely related to the Common Cuckoo build a nest and raise their own chicks, and until today the degree of variation in parental care within the family of cuckoos is believed to be unmatched by any other bird family Payne a.

These approaches could be complemented by long-term individual-based studies to look at real fitness effects of brood parasitism by measuring LRS for host individuals. This article has been cited by other articles in PMC. There is good evidence that the risk of being parasitized is not equal between individuals of a host population or between host populations, and neither is it equal across an individual host’s lifespan Lotem et al. However, by far the best-studied adaptation of brood parasites to egg rejection of hosts is egg mimicry Davies ; Grim ; Payne a.

Soon after hatching, parasitic chicks of most cuckoo species and the honeyguides eliminate competition with host chicks through eviction or killing Davies ; Payne a. Using a maximum-likelihood approach Pagelit was possible to construct the most likely evolutionary pathway between the presumed ancestral state and that displayed by modern brood parasitic species figure 1.

All of these puzzles are examined in descriptions of the natural history of each of the groups of parasites in turn. How is this arms race conducted?
