Conspecific brood parasitism and population dynamics.
Conspecific 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 survival; randomness of parasitic egg dist...
متن کاملInterspecific egg rejection as ecological collateral damage from selection driven by conspecific brood parasitism
http://dx.doi.org/10.1016/j.anbehav.2015.02.010 0003-3472/© 2015 The Association for the Study of A Distinguishing between interspecific and intraspecific coevolution as the selective driver of traits can be difficult in some taxa. A previous study of an avian obligate brood parasite, the black-headed duck, Heteronetta atricapilla, suggested that egg rejection by its two main hosts (two species...
متن کاملFirst Evidence of Conspecific Brood Parasitism and Egg Ejection in Song Sparrows, with Comments on Methods Sufficient to Document These Behaviors
Conspecific brood parasitism occurs in many songbird species but has not been reported in Song Sparrows (Melospiza melodia). In three separate study areas where breeding Song Sparrows experience heavy nest predation pressure and Brownheaded Cowbird (Molothrus ater) parasitism, we observed six instances in which newly laid eggs were attributable to female Song Sparrows other than the nest owners...
متن کاملPaternity-parasitism trade-offs: a model and test of host-parasite cooperation in an avian conspecific brood parasite.
Efforts to evaluate the evolutionary and ecological dynamics of conspecific brood parasitism in birds and other animals have focused on the fitness costs of parasitism to hosts and fitness benefits to parasites. However, it has been speculated recently that, in species with biparental care, host males might cooperate with parasitic females by allowing access to the host nest in exchange for cop...
متن کاملBegging and cowbirds: brood parasites make hosts scream louder
Avian brood parasites have evolved striking begging ability that often allows them to prevail over the host progeny in competition for parental resources. Host young are therefore selected by brood parasites to evolve behavioral strategies that reduce the cost of parasitism. We tested the prediction that the intensity of nestling begging displays functioning to attract parental care increases a...
