Using 3D printed eggs to examine the egg-rejection behaviour of wild birds [PDF]
PeerJ, 2015 The coevolutionary relationships between brood parasites and their hosts are often studied by examining the egg rejection behaviour of host species using artificial eggs.

Contrasting effects of egg size and appearance on egg recognition and rejection response by Oriental reed warblers [PDF]
Ecology and Evolution, 2020 Background Among potential hosts, the rejection of foreign eggs, which is a common and effective strategy to counter brood parasitism, depends on egg recognition.

A Meta-Analysis of Avian Egg Traits Cueing Egg-Rejection Defenses Against Brood Parasitism [PDF]
Frontiers in Ecology and Evolution, 2021 The capability of hosts to reject the odd egg from their nest is one of the key defenses against avian brood parasitism. Considerable research effort has been devoted to exploring which phenotypic traits of eggshells facilitate to cue the recognition of ...

Experimental shifts in intraclutch egg color variation do not affect egg rejection in a host of a non-egg-mimetic avian brood parasite. [PDF]
PLoS ONE, 2015 Avian brood parasites lay their eggs in the nests of other birds, and impose the costs associated with rearing parasitic young onto these hosts. Many hosts of brood parasites defend against parasitism by removing foreign eggs from the nest.

Egg Rejection and Nest Sanitation in an Island Population of Barn Swallows (Hirundo rustica): Probability, Response Latency, and Sex Effects [PDF]
Animals, 2022 Bird nests function as vessels for eggs and nestlings, and an environment for rearing offspring. However, foreign objects falling into bird nests and nestling eggshells may be harmful.

Host personality and seasonal parasitism risk do not account for egg rejection behavior in the azure-winged magpie [PDF]
International Journal for Parasitology: Parasites and WildlifeBrood parasitism reduces the reproductive success of hosts and many host birds have evolved a range of anti-parasitism strategies, including egg recognition and egg rejection.

Cuckoo Hosts Fine‐Tune Their Egg Rejection After Experiencing a Parasitism Event [PDF]
Ecology and EvolutionRecognising and rejecting parasitic eggs is one of the most common anti‐parasitism strategies used by host birds. However, the egg rejection of some hosts exhibits behavioural plasticity.

Divergent Egg‐Rejection Strategies Between Laying and Incubation Periods in the Green‐Backed Tit (Parus monticolus) [PDF]
Ecology and EvolutionEgg recognition and rejection constitute essential host defenses against brood parasitism, with rejection decisions reflecting evolutionary adaptations shaped by cost–benefit trade‐offs.

Geographical Variation in Egg Rejection by Azure‐Winged Magpies (Cyanopica cyanus) Across China [PDF]
Ecology and EvolutionBrood parasitism negatively affects the reproductive success of hosts, leading many hosts to evolve defense strategies to recognize and reject parasitized eggs.

Lifetime expression of egg rejection behaviour in Eurasian magpies is associated with variation in a polymorphic genetic marker [PDF]
Scientific ReportsObligate avian brood parasitism is a reproductive strategy in which parasitic birds rely entirely on host species for incubation and chick rearing, reducing host reproductive success.
