Brood parasitism and host responses continue to attract a disproportional interest from researchers because the avian parasite—host system is not only one of cheags best models for the coevolutionary process, but is also uniquely tractable and open to experimental manipulation.

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. D, Marchetti M, Brooke M. Darwin commented on the small egg of the Common Cuckoo, and Payne showed cosbirds brood parasitic cuckoos lay smaller eggs than cuckoos of the same size with parental care. Modelling the population dynamics of a cuckoo—host association and the evolution of host defences.

Cuckoos, Cowbirds and Other Cheats. In the parasitic finches, imprinting on host song is crucial for parasitic males’ later mating success Payne et al. Contents 1 A monstrous outrage on maternal affection. This article has been cited by other articles in PMC. The scheme of coevolution in parasite—host systems is illustrated in figure 2the coevolutionary anr are well illustrated by egg colouration and egg size as I shall now discuss.

Brood parasitic cowbird nestlings use host young to procure resources. Feasting, Fowling and Feathers. Read, highlight, and take notes, across web, tablet, and phone. Cuckoos, cowbirds and other cheats. Is greater eggshell density an alternative mechanism by which parasitic cuckoos increase the strength of their eggs?

However, if the fitness of the alternative strategy was lower than the current strategy, this would support the evolutionary equilibrium hypothesis. This website uses cookies to improve user experience.

Constraints on egg discrimination and cuckoo—host co-evolution. Recognition errors and probability of parasitism determine whether reed warblers should accept or reject mimetic eggs.

Customer Reviews Review this book. Hume’s Leaf Warblers from India studied by Marchetti showed a very high rejection rate of the larger parasitic eggs and it is unlikely that the large parasite could ever evolve an egg small enough to mimic the tiny host’s egg.

This experimental approach could be viewed as a perturbation analysis of a matrix analysis to test whether the reduction of a matrix element here reproductive success has fitness consequences Caswell Another possible means of defence against parasitism at the chick stage has been suggested by Grim et al.

About this book Cuckoos and cowbirds are amongst the select bird groups renowned as professional parasites, who always lay their eggs in the nests of other species, and this book describes the natural histories of all the brood parasites and examines the exciting questions they raise about the evolution of cheating and the arms race between parasites and their hosts.

Signals of need in parent—offspring communication and their exploitation by the common cuckoo.

A, Bicik V, Moskat C. A, Chaline N, Stewart I.

In all cuckoo—host systems, this mechanism would enable chick recognition to evolve. The evolutionary lag hypothesis proposes that it would be advantageous for hosts to counteract brood parasitism but they ccheats not, either because there has been insufficient time for the defence to spread through otger host species population or because hosts might lack the genetic variation to evolve a defence against brood parasitism Rothstein Under which circumstances could it not be the best option to reject a parasitic egg?

Habitat and space use of European cuckoo females during the egg laying period.
