Can nest design hinder brood parasitism success?
Journal of Avian BiologyAvian nest design varies depending on environmental factors but may also be influenced by between‐species interactions. In the brood parasitism context, hosts may evolve nest architectures that may limit parasite access to the nest cup, reduce parasite ...

Egg‐Inspection Frequency Predicts Egg Recognition but Not Ejection in a Cuckoo Host [PDF]
Ecology and EvolutionOne of the most effective strategies for avian hosts to defend against brood parasitism is to reject the parasitic egg from the focal nest. However, substantial inter‐individual variability in egg‐rejection behavior remains unexplained.

Egg Retrieval as a Cognitive Indicator in Cuckoo Hosts [PDF]
Ecology and EvolutionEgg retrieval behavior in hosts within avian brood parasitism systems was found to be regulated by the motivation to reject parasitic eggs. However, due to the limitations in the research systems, there is a lack of effective validation regarding the ...

Double Parasitism by Two Cuckoo Gentes in a Daurian Redstart Nest. [PDF]
Ecol EvolDouble parasitism is rare in forest‐breeding hosts of the common cuckoo, where females typically defend exclusive territories. We report a unique case in a Daurian redstart nest involving two different cuckoo gentes, despite one gens overwhelmingly dominating parasitism events in the population. This observation suggests that female cuckoos may be less

The neuroethology of avian brood parasitism [PDF]
Journal of Experimental Biology, 2021 ABSTRACTObligate brood-parasitic birds never build nests, incubate eggs or supply nestlings with food or protection. Instead, they leave their eggs in nests of other species and rely on host parents to raise their offspring, which allows the parasite to continue reproducing throughout the breeding season. Although this may be a clever fitness strategy,

The overlooked complexity of avian brood parasite–host relationships [PDF]
Ecology Letters, 2022 Abstract The relationships between avian brood parasites and their hosts are widely recognised as model systems for studying coevolution. However, while most brood parasites are known to parasitise multiple species of host and hosts are often subject to parasitism by multiple brood parasite species, the examination of multispecies ...

Ecological Context Constrains Host-Associated Genetic Structure in the Common Cuckoo. [PDF]
Ecol EvolHost specialization is often expected to generate population genetic structure, yet this relationship remains unclear in highly mobile species. Using the common cuckoo in South Korea, we show that genetic structure is exceptionally weak across the mainland despite ecological heterogeneity and multiple host species, with differentiation emerging only ...

Environmental Drivers on Blue Tit Nest Microbiome: An Experimental Study. [PDF]
Ecol EvolElevated humidity and temperature altered nest microbial composition and its associations with parasitism and nestling condition. These findings identify nest microclimate as an important driver of nest microbiomes with consequences for avian development.
