Can nest design hinder brood parasitism success?

Journal of Avian Biology
Avian 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 ...

Quintuple parasitism of a great reed warbler nest by common cuckoos

Ecology and Evolution, 2021
Multiple parasitism in obligate avian brood parasites occurs when several brood parasitic females lay their eggs in the nest of the same host. While multiple parasitism is common in the highly social, nonevicting cowbird species (Molothrus sp.), in which

Avian Egg Timers: Female Cowbirds Judge Past, Present, and Future When Making Nest Parasitism Decisions

Frontiers in Ecology and Evolution, 2020
The cognitive demands associated with brood parasitism are substantial. Not only must female parasites locate nests and assess their suitability for parasitism, they must also time parasitism to correspond with the breeding behavior of the host.

Eggs in the freezer: energetic consequences of nest site and nest design in Arctic breeding shorebirds [PDF]

, 2012
Birds construct nests for several reasons. For species that breed in the Arctic, the insulative properties of nests are very important. Incubation is costly there and due to an increasing surface to volume ratio, more so in smaller species. Small species

Differential effects of elevated nest temperature and parasitism on the gut microbiota of wild avian hosts

Animal Microbiome, 2021
Background Changes in wild animal gut microbiotas may influence host health and fitness. While many studies have shown correlations between gut microbiota structure and external factors, few studies demonstrate causal links between environmental ...

Differential parasitism by four species of phorid flies when attacking three worker castes of the leaf-cutting ant Atta laevigata (Smith, 1858).

PLoS ONE, 2021
Certain species of parasitic flies belonging to the Phoridae are known to attack Atta spp. workers foraging along trails, near nest openings used by the ants to supply the colony with plant material, and in the areas where the ants are actively cutting ...

Public information and conspecific nest parasitism in goldeneyes: targeting safe nests by parasites [PDF]

, 2006
Conspecific nest parasitism (CNP) is a widespread alternative reproductive tactic in birds. Several hypotheses have been put forward to explain the evolution and occurrence of CNP, but no generally applicable hypothesis exists.

Reproductive Strategies Change With Time in a Newly Founded Colony of Spotless Starlings (Sturnus unicolor)

Frontiers in Ecology and Evolution, 2021
Variation in avian reproductive strategies is often studied from a comparative perspective, since even closely-related taxa differ greatly in the degree of polygyny, extra-pair paternity (EPP) or intra-specific brood-parasitism.

Overwinter users of nest cavities affect breeding birds via nest‐dwelling ectoparasites

Ecosphere, 2023
Cavities used for avian reproduction in spring often host other organisms for roosting during winter, which should affect their microclimatic conditions and, then, the patterns of emergence of nest‐dwelling ectoparasites of birds and successful ...

Nest desertion as an anti-parasitism strategy in hosts selects for late egg-laying behavior in cuckoos

iScience, 2023
Summary: Studies have shown that brood parasites lay their eggs early in the egg-laying sequence of their hosts, providing them with the advantage of earlier hatching.
