A Model System For Coevolution: Avian Brood Parasitism
Annual Review of Ecology and Systematics, 1990Many putative examples of coevolution do not stand up to critical analysis. A rigorous definition of coevolution requires that a trait in one species has evolved in response to a trait of another species, which trait was itself evolved in response to the first species (50, 69).

Egg recognition and counting reduce costs of avian conspecific brood parasitism
Nature, 2003Birds parasitized by interspecific brood parasites often adopt defences based on egg recognition but such behaviours are puzzlingly rare in species parasitized by members of the same species. Here I show that conspecific egg recognition is frequent, accurate and used in three defences that reduce the high costs of conspecific brood parasitism in ...

An Experimental and Teleonomic Investigation of Avian Brood Parasitism
The 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.

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.

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.

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,

Abstract Avian brood parasitism is the association between a bird (the parasite) that lays its eggs in the nests of another (the foster or host species), thus gaining the care of the foster parent. The young brood parasite takes the food that the foster parents bring for their own young, often at a cost of the survival of the foster ...
