Interspecific brood parasitism represents a prime example of the coevolutionary arms race where each party has evolved strategies in response to the other. Here, we investigated whether common cuckoos (Cuculus canorus) actively select nests within a host population to match the egg appearance of a particular host clutch. To achieve this goal, we quantified the degree of egg matching using the avian vision modelling approach. Randomization tests revealed that cuckoo eggs in naturally parasitized…

Why cuckoos should parasitize parrotbills by laying eggs randomly rather than laying eggs matching the egg appearance of parrotbill hosts?
No evidence is found for the hypothesis that cuckoos lay eggs based on own egg color matching that of the parrotbill-cuckoo system, and it is argued theoretically that laying eggs matching those of the hosts in this system violates a key trait of the life history of cuckoo and therefore should be maladaptive.
Criteria for host selection in a brood parasite vary depending on parasitism rate
The findings support the hypothesis that active selection will become a more prevalent great spotted cuckoo laying strategy when cuckoos have a larger availability of host nests to choose among and predict that parasites should more likely select phenotypic traits indicating host quality when this is relatively low.
Modeling the cuckoo’s brood parasitic behavior in the presence of egg polymorphism
A time sequence of parasitic events in which a cuckoo finds host nests and decides to parasitize them or not in the presence of egg polymorphism is modeled and it is shown that either of the two strategies can be optimal.
Naïve hosts of avian brood parasites accept foreign eggs, whereas older hosts fine-tune foreign egg discrimination during laying
These results are consistent with the hypotheses that naïve hosts need to see and learn the appearance of their own eggs to discriminate and reject foreign eggs, whereas experienced breeders possess a recognition template of theirown eggs and reject parasitic eggs even without having to see their own egg.
Errors in egg‐laying by female Common Cuckoo Cuculus canorus in nests of its common host
Evaluating egg‐laying patterns and errors related to the timing of egg-laying in the Common Cuckoo Cuculus canorus will help to understand better the mechanism of co‐evolutionary arms races and differences between host specialist and generalist brood parasites in various host–parasite systems.
Nest destruction elicits indiscriminate con- versus heterospecific brood parasitism in a captive bird
It is found that zebra finches laid physiologically committed eggs indiscriminately between nests containing conspecific eggs and nests containing heterospespecific eggs (of Bengalese finches, Lonchura striata vars), despite the con- and heterosPEcific eggs differing in both size and coloration.
Great spotted cuckoos show dynamic patterns of host selection during the breeding season. The importance of laying stage and parasitism status of magpie nests
It is detected that cuckoos preferred to parasitize magpie nests at the laying stage but, mainly, those that already harbored one or two cuckoo eggs, which may seem counterintuitive, implies that brood parasite–host interaction is dynamic depending on phenology.
Visual discrimination of polymorphic nestlings in a cuckoo-host system
Nestling polymorphism may be a trace of evolutionary past and may only have a marginal role in true-recognition of nestlings in the arms race in New Caledonia, and visual discrimination alone may result in higher chances of recognition errors in polymorphic than in monomorphic host broods.
Egg-spot matching in common cuckoo parasitism of the oriental reed warbler: effects of host nest availability and egg rejection
The data suggest that both the high temporal encounter rate between cuckoo and warbler nests as well as the high egg rejection ability of the host are important factors for egg-spot matching of the cuckoos.


Are Cuckoos Maximizing Egg Mimicry by Selecting Host Individuals with Better Matching Egg Phenotypes?
It is argued that the existence of an ability to select host nests to maximize mimicry by brood parasites appears unlikely, but this possibility should be further explored in cuckoo-host systems where the host has evolved discrete egg phenotypes.
Rapid increase in cuckoo egg matching in a recently parasitized reed warbler population
Tests for temporal change in degree of matching between eggs of the parasitic European cuckoo and its reed warbler host during 24 consecutive years in a recently parasitized reedwarbler population provide tentative support for the cuckoos preference hypothesis suggesting that cuckOO‐host egg matching could partially be due to cuckoff females selecting host nests based on the appearance of their eggs.
Do cuckoos choose nests of great reed warblers on the basis of host egg appearance?
This work tested the hypothesis that egg matching could be improved by cuckoos choosing nests in which host eggs more closely match their own, by assessing matching and monitoring nest fate in great reed warblers naturally or experimentally parasitized by eggs of European cuckoo.
Are dark cuckoo eggs cryptic in host nests?
Conflict between egg recognition and egg rejection decisions in common cuckoo (Cuculus canorus) hosts
Common cuckoos (Cuculus canorus) are obligate brood parasites, laying eggs into nests of small songbirds. The cuckoo hatchling evicts all eggs and young from a nest, eliminating hosts’ breeding
Egg Discrimination in an Open Nesting Passerine Under Dim Light Conditions
Study of egg rejection behaviour in nightingales, an open-nesting species that nests in deeply shadowed positions and lays very specific dark olive-green eggs, found blue and white eggs were rejected at a higher relative rate than the better achromatic matching black and green eggs.
Common Cuckoos Cuculus canorus change their nest-searching strategy according to the number of available host nests
It is found that nest visibility, reed density and timing of breeding predicted brood parasitism of Great Reed Warblers Acrocephalus arundinaceus by the Common Cuckoo Cuculus canorus, and that Cuckoos females are able to optimize their nest-searching strategy.
Egg colour mimicry in the common cuckoo Cuculus canorus as revealed by modelling host retinal function

Cuckoo races as assessed by humans do not entirely match with host perception of matching and that achromatic mechanisms could play a main role in the discrimination of cuckoo eggs at low-light levels.
Why is mimicry in cuckoo eggs sometimes so poor
The selection pressure exerted by the host on the parasite should be weaker than if brood parasitism was randomly distributed among naive and experienced breeders and affect adaptations such as egg mimicry, which could explain the existence of imperfect adaptations in some brood parasite-host systems.
