Bird brood parasitism
For many animals, the effort to rear their young is considerable. In birds, this often includes building nests, incubating eggs, feeding the chicks, and protecting them from predators. Perhaps for this reason, about 1% of birds (around 100 species) save themselves the effort and cheat instead. They are obligate brood parasites, laying their eggs in the nests of other species and leaving the hos...
متن کاملNest destruction elicits indiscriminate con- versus heterospecific brood parasitism in a captive bird
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...
متن کاملInterspecific brood parasitism in galliform birds
Mode of development in birds helps determine the form of brood parasitism a species exhibits. Most knowledge of precocial brood parasites comes from a single avian family, the waterfowl (Anatidae: Anseriformes). Here we review cases of interspecific brood parasitism (IBP) in a second group of precocial birds, the order Galliformes. IBP is uncommon but taxonomically widespread, occurring in at l...
متن کاملConspecific 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 کاملMode of development and interspecific avian brood parasitism
Avian interspecific brood parasites differ considerably in their commitment to parasitism; 87 species are obligate brood parasites, whereas 35 species are known to be facultative brood parasites. This variation is strongly related to mode of development. Obligate parasitism is found almost exclusively in altricial species, whereas facultative interspecific parasitism is predominant in precocial...
