Egg removal and intraspecific brood parasitism in the European starling (Sturnus vulgaris) [PDF]
Behavioral Ecology and Sociobiology, 1989 From 1983 to 1986 we monitored 284 European starling ( Sturnus vulgaris ) nests in New Jersey for evidence of intraspecific brood parasitism and egg removal during the laying period.

Imprinting in an interspecific brood parasitic bird
Proceedings of the Royal Society B: Biological Sciences, 2023Many animals learn to recognize conspecifics after an early experience with them through sexual imprinting. For brood parasitic birds, it is not possible to develop conspecific recognition using cues provided by their foster parents.

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,

Cuckoos, cowbirds and the persistence of brood parasitism
Trends in Ecology and Evolution, 1999Brood parasites provide a particularly good opportunity for the study of host-parasite evolution because they directly affect the reproductive success of their hosts. Two parasitic species, the common cuckoo (Cuculus canorus) and the brown-headed cowbird (Molothrus ater), differ widely in their relationships with their hosts, yet share the attribute of

Brown-headed Cowbirds Molothrus ater are very social birds. Males have a rich vocal repertoire, and much of their social behavior is mediated by vocalizations. For example, subtle differences in song reflect dominance status and are used by females during mate choice.

Abstract Brood parasitism is the most fascinating feature of cuckoo biology. Cuckoo parasites use other species to rear their young, and how the behavior evolved as a reproductive strategy demands an explanation (Darwin 1859, Hamilton 1972).

Conspecific Brood Parasitism and Population Dynamics
The American Naturalist, 2008Conspecific brood parasitism (CBP), defined as parasitic laying of eggs in a conspecific nest without providing parental care, occurs in insects, fishes, amphibians, and many birds. Numerous factors have been proposed to influence the evolution of CBP, including nest site limitation; effects of brood size, laying order, or parasitic status on offspring

Abstract The evolutionary, ecological and behavioral questions posed by obligate brood parasites are among the most intriguing of all contemporary ornithological topics. Avian brood parasites lay their eggs in the nests of other birds and may be a major contributing factor driving several species of songbirds to near extinction.
