Endocrine regulation of egg rejection in an avian brood parasite host
Biology Letters, 2020 Abstract Parasite–host coevolution can lead to novel behavioural adaptations in hosts to resist parasitism. In avian obligate brood parasite and host systems, many host species have evolved diverse cognitive and behavioural traits to recognize and reject parasitic eggs.

Evolution of Avian Brood Parasitism and Phylogenetic History of Brood Parasites
2017The fascination with avian brood parasitism has spawned a wealth of research into breeding strategies and their evolutionary consequences. Yet until today, there is no clear consensus how brood parasitism has evolved. On current evidence, it is more likely that interspecific brood parasitism evolved directly from an ancestral species with parental care,

An Experimental and Teleonomic Investigation of Avian Brood Parasitism
Condor, 1975The term “teleonomy” has been suggested by Williams (1966:258) to describe the scientific study of adaptations. Williams indicated that relatively few evolutionary studies deal primarily with teleonomy despite the fact that adaptation is the most basic feature of evolution and of all biology.

A siblicidal origin for avian brood parasitism?
Journal of Ornithology, 2015We present a model for the evolution of host selection by avian brood parasites from the ecological context of siblicidal brood reduction tactics. Our analysis concentrates on the fitness costs and benefits that permit the evolution of brood parasitism as an adaptive strategy from a state of obligate parental care already featuring siblicide.

Polymorphism in Avian Brood Parasitism: A Coevolutionary Perspective
Ornithological Science, 2016Polymorphism provides a classic example of adaptive evolution. A great advantage of studying polymorphism is that the phenotype can serve as a genetic marker; therefore, researchers can take full advantage of this to test a hypothesis based on Darwin's principle of adaptive evolution.

Population Dynamics of Avian Brood Parasitism
The American Naturalist, 1985The population dynamics of avian brood parasitism have received little attention in spite of mounting evidence that many host species are adversely affected by brood parasites. We develop models for the dynamics of brood parasitism and apply these models to host-parasite associations for which demographic data are available.

The effect of avian brood parasitism on physiological responses of host nestlings
Oecologia, 2021Avian obligate brood parasites lay their eggs in the nests of other species that may provide care for the foreign offspring. Brood parasitism often imparts substantial fitness losses upon host nestlings when they are raised alongside the typically more competitive, larger, and older parasitic chick(s).

Advances in the Study of Coevolution Between Avian Brood Parasites and Their Hosts [PDF]
Annual Review of Ecology, Evolution, and Systematics, 2014 The interactions between avian obligate interspecific brood parasites and their hosts provide tractable systems for studying coevolutionary processes in nature. This review highlights recent advances in understanding coevolution in these systems. First, we discuss the evolution and phylogenetic history of avian brood parasitism.
