How Do Oriental Reed Warblers Recognize Cuckoo Eggs? [PDF]

open access: yesEcol Evol
The cognitive basis and underlying mechanisms of the host egg rejection behavior remain not well understood. Egg recognition experiments using three egg mimicry levels (non, poorly, and highly mimetic eggs) to observe Oriental reed warbler (Acrocephalus orientalis) behavior at three breeding stages (pre‐egg‐laying, single host egg, and multiple host ...

The neuroethology of avian brood parasitism [PDF]

open access: yesJournal of Experimental Biology, 2021
ABSTRACTObligate brood-parasitic birds never build nests, incubate eggs or supply nestlings with food or protection. Instead, they leave their eggs in nests of other species and rely on host parents to raise their offspring, which allows the parasite to continue reproducing throughout the breeding season. Although this may be a clever fitness strategy,

Coevolution of acoustical communication between obligate avian brood parasites and their hosts

open access: yesAvian Research, 2020
The mutually antagonistic processes producing adaptations and counter-adaptations in avian brood parasites and their hosts provide a model system for the study of coevolution; this topic has long been an area of focus in ornithology and evolutionary ...

Importance of cooperation: How host nest defenses effectively prevent brood parasitism from the cuckoos

open access: yesiScience, 2023
Summary: As the frontline defense against avian brood parasitism, nest defense is important in reducing nest parasitism and increasing host fitness.

Extreme offspring ornamentation in American coots is favored by selection within families, not benefits to conspecific brood parasites [PDF]

open access: yes, 2019
Offspring ornamentation typically occurs in taxa with parental care, suggesting that selection arising from social interactions between parents and offspring may underlie signal evolution.

Coevolution in action: disruptive selection on egg colour in an avian brood parasite and its host. [PDF]

open access: yesPLoS ONE, 2010
Trait polymorphism can evolve as a consequence of frequency-dependent selection. Coevolutionary interactions between hosts and parasites may lead to selection on both to evolve extreme phenotypes deviating from the norm, through disruptive selection.Here,

An Experimental Test of Defenses Against Avian Brood Parasitism in a Recent Host

open access: yesFrontiers in Ecology and Evolution, 2021
Theoretical studies predict that hosts of avian brood parasites should evolve defenses against parasitism in a matter of decades. However, opportunities to test these predictions are limited because brood parasites rarely switch to naïve hosts.

Molecular Genetic Perspectives on Avian Brood Parasitism [PDF]

open access: yesIntegrative and Comparative Biology, 2002
Advances in molecular genetic techniques have provided new approaches for addressing evolutionary questions about brood parasitic birds. We review recent studies that apply genetic data to the systematics, population biology, and social systems of avian brood parasites and suggest directions for future research.
