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.

The basis for female choice in an avian brood parasite
Behavioral Ecology and Sociobiology, 1991Behavioral observation and experimental manipulation of a marked population of brood parasitic brown-headed cowbirds (Molothrus ater) were conducted to determine whether or not females exhibit mate choice and to elucidate the ultimate basis for any such choice.

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 ...

Immune Function in an Avian Brood Parasite and Its Nonparasitic Relative
Physiological and Biochemical Zoology, 2013Organisms that breed multiple times must trade off resources between current and future reproduction. In many species, sexual selection can lead to reduced levels of immune function in males because they invest heavily in current reproduction at the expense of self-maintenance.

The Evolution and Ecology of Avian Brood Parasitism An Overview
1998Abstract The ludicrous sight of a fledgling cuckoo or cowbird being fed by an adult host less than half its size (cover of book) makes it easy to see why parasitic birds have attracted so much attention. A person would have to be devoid of all curiosity to not wonder how such a relationship arose between two very different species and ...

Modelling the arms race in avian brood parasitism
Evolutionary Ecology, 1998In brood parasitism, interactions between a parasite and its host lead to a co-evolutionary process called an arms race, in which evolutionary progress on one side provokes a further response on the other side. The host evolves defensive means to reduce the impact of parasitism, while the parasite evolves means to counter the host's defence.
