Mode 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...
متن کاملBird 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 کاملThe costs of avian brood parasitism explain variation in egg rejection behaviour in hosts.
Many bird species can reject foreign eggs from their nests. This behaviour is thought to have evolved in response to brood parasites, birds that lay their eggs in the nest of other species. However, not all hosts of brood parasites evict parasitic eggs. In this study, we collate data from egg rejection experiments on 198 species, and perform comparative analyses to understand the conditions und...
متن کاملAvian colour perception predicts behavioural responses to experimental brood parasitism in chaffinches.
Hosts of cuckoos have evolved defences allowing them to discriminate and reject parasite eggs. Mechanisms of discrimination are mostly visually mediated, and have been studied using approaches that do not account for what the receiver (i.e. host) actually can discriminate. Here, for the first time we apply a perceptual model of colour discrimination to study behavioural responses to natural var...
