Mixed Parentage Broods Indicate Group Spawning in the Brood Parasitic Cuckoo Catfish
Molecular EcologyABSTRACT Obligate brood parasites delegate the workload of costly parental care to their hosts. Theory predicts that release from demanding parental care increases the importance of other factors to shape mating patterns. However, behavioural observations and parentage estimates are notoriously difficult to obtain

Cowbirds use conspecific social information to detect host nests in the wild
Ibis, Volume 168, Issue 2, Page 799-804, April 2026.Recent work shows that hosts of avian brood parasites use social information to increase egg rejection rates, but fewer studies explore how parasites themselves use such information to detect host nests in the wild. To determine whether wild Brown‐headed Cowbirds Molothrus ater use social information to detect host nests, we measured how individual ...

Understanding earwig phenology in top fruit orchards [PDF]
, 2008 Earwigs, Forficula auricularia, are key generalist predators to a variety of orchard pests. However, numbers of earwigs have declined in both organic and IPM orchards in recent years. Both Integrated and Organic fruit growers have tried to re-establish

Evolutionary Trickery: Brood Parasitism in Synodontis multipunctatus [PDF]
, 2011 Obligate brood parasitism, the act of reproducing by exploiting the parental investment of a host species to raise young, is fairly well known among bird species (Cruz et al. 2004 Encycl. Anim. Behav. ed. M. Bekoff.

Cooperation and conflict in conspecific brood parasitism : an alternative reproductive tactic [PDF]
, 2009 Interactions among individuals give rise to both cooperation and conflict. Individuals will behave selfishly or altruistically depending on which gives the higher payoff.

Video evidence that cuckoos farm their hosts by ejecting nestlings
Ecology and EvolutionWhen host nests are scarce, avian brood parasites would benefit from behaviours that increase the availability of suitable nests. Several studies reported ejection of host nestlings from nests by brood parasites; however, whether brood parasites do so to

Journal of Avian BiologyObligate brood parasitism is a peculiar behaviour found in some bird species. The costs for their hosts can be high, generating selection for active defence strategies including foreign egg and chick rejection.

Journal of Avian BiologyBrood parasitism can be costly to host fitness, which in turn may favour host strategies that decrease these costs. Duck (Anatinae) nests are often parasitized by eggs of other ducks, and one way that hosts can respond to potentially costly brood ...

Brood parasitism by shiny cowbirds
, 2016 Brood parasitic birds lay eggs amongst the clutches of other species, which then assume all costs of parental care on their behalf. This thesis addresses several puzzles of avian brood parasitism, using field studies and theoretical modelling of the generalist parasite, the shiny cowbird (Molothrus bonariensis) and select hosts in Argentina.
