Penguin Press; Harmondsworth, UK: T, Korsnes L, Lampe H. Indeed, Soler et al. If parasite—host systems represent the coevolutionary process, these situations need an explanation. Are blackcaps current winners in the evolutionary struggle against the common cuckoo? Feasting, Fowling and Feathers.

Read, highlight, and take notes, across web, tablet, and phone. Biological Sciences are provided here courtesy of The Royal Society. A, Cuckols N, Stewart I. Breeding biology of brood parasitic cowbirds characterized by parent—offspring and sibgroup reconstruction.

Cuckoos, Cowbirds and Other Cheats

Variation in growth of brown-headed cowbird Molothrus ater nestlings and energetic impacts on their host parents. Ultraviolet reflectance of great spotted cuckoo eggs and egg discrimination by magpies.

A few studies have tried to determine what cues are used by brood parasites to locate host nests. Other titles from Poyser. Hence, nest-site selection and nest architecture can influence reproductive success of the host and there are instances of stabilizing and directional selection.

Breeding success of common cuckoos Cuculus canorus parasitising four sympatric species of Acrocephalus warblers.

Cuckoos, cowbirds and hosts: adaptations, trade-offs and constraints

As mentioned earlier, there is some evidence for the nesting-exposure hypothesis: The origin of species by means of natural selection. Recognition errors and probability of parasitism determine whether reed warblers should accept or reject mimetic eggs.

Will defenseless hosts develop defenses in time, or are there constraints which limit the evolution and perfection of host defenses? Abstract The interactions between brood parasitic birds and their host species provide one of the best model systems for coevolution. Kattan showed that shiny cowbird eggs chheats a reduced energy content to reduce incubation length.

It would be interesting to test the Superb Fairy-wrens on this: For example, Kilner et al. A previously unknown adaptation in a cuckoo chick comes from a study of the Horsfield’s Hawk-cuckoo Hierococcyx hyperythrus in Japan. Cuckoos and cowbirds versus hosts: Cuckoos, cowbirds and the persistence of brood parasitism. Given that both egg rejection and acceptance have costs and benefits, an optimality approach can be applied to cheqts out a threshold frequency of brood parasitism above which egg rejection results in higher reproductive success and below which egg acceptance is favoured.

Recent evidence suggests that begging calls and especially the response to parental alarm calls can be host specific and differ between gentes of Common Cuckoos Butchart et al.

Clutch characteristics and egg discriminate ability of the African village weaverbird Ploceus cucullatus.

You can unsubscribe from newsletters at any time by clicking the unsubscribe link in any newsletter. Mode of development and interspecific cowbirvs brood parasitism.

Two scenarios are conceivable figure 4: Such non-randomness has been documented for nest sites of hosts: While the generalist brood parasitic cowbird species do not exhibit egg mimicry for the great majority of their hosts, many cuckoo species lay mimetic eggs, sometimes indistinguishable from the host egg for the human eye Langmore et al. The evolution of cuckoo parasitism: Population Ecology of Raptors.

In all cuckoo—host systems, this mechanism would enable chick recognition to evolve.

Soon after hatching, parasitic chicks of most cuckoo species and the honeyguides eliminate competition with host chicks through eviction or killing Davies ; Payne a. All else being equal, parasitic females should select host parents of high quality. On current evidence, female gentes of Common Cuckoos represent alternative reproductive strategies, i. Published six times a year, British Wildlife bridges the gap between popular writing and scientific literature through a combination of long-form articles, regular columns and reports, book reviews and letters.

British Wildlife cuckops the leading natural history magazine in the UK, providing essential reading for both enthusiast and professional naturalists and wildlife conservationists.

The Common Cuckoo—Dunnock system would be an example of continued exploitation with no host oyher. The hormonal control of begging and early aggressive behaviour: Benton Richard Fortey View All. Darwin commented on the small egg of the Common Cuckoo, and Payne showed that brood parasitic cuckoos lay smaller eggs than cuckoos of the same size with parental care.

Age and reproduction in birds—hypotheses and tests.

Obligate brood parasites as selective agents for evolution of egg appearance in passerine birds. Cuckoos, Cowbirds and Other Cheats. This preferential treatment can be achieved through the parasitic chick being larger Liversidge ; Dearbornproviding extra stimuli that facilitate preferential treatment Soler et al. In this fascinating new book, Nick Davies describes the natural histories of these brood parasites and examines many of the exciting questions they raise about the evolution of cheating and the arms race between parasites and their prey.
