Nest destruction elicits indiscriminate con- versus heterospecific brood parasitism in a captive bird [Ecology and Evolution]

by Frédéric Magné - published on , updated on

Following nest destruction, the laying of physiologically committed eggs (eggs that are ovulated, yolked, and making their way through the oviduct) in the nests of other birds is considered a viable pathway for the evolution of obligate interspecific brood parasitism. While intraspecific brood parasitism in response to nest predation has been experimentally demonstrated, this pathway has yet to be evaluated in an interspecific context.(...)
