Avian brood parasitism in Italy: another perspective

open access: yesAvocetta, 2020
We present a quantitative analysis of the data reported in the only published review of parasitism frequency on hosts of Common Cuckoo Cuculus canorus in a Mediterranean area. We first eliminated a bias potentially introduced by the method by which data

Importance of cooperation: How host nest defenses effectively prevent brood parasitism from the cuckoos

open access: yesiScience, 2023
Summary: As the frontline defense against avian brood parasitism, nest defense is important in reducing nest parasitism and increasing host fitness.

The Evolution of Predator Resemblance in Avian Brood Parasites [PDF]

open access: yesFrontiers in Ecology and Evolution, 2021
Predators have profound effects on prey behavior and some adult brood parasites use predator resemblance to exploit the antipredator defenses of their hosts.

Use of 3D-printed animal models as a standard method to test avian behavioral responses toward nest intruders in the studies of avian brood parasitism

open access: yesAvian Research, 2022
Living and/or non-living animal models are often used as stimuli to observe the behavioral responses of the target animals. In the past, parasites, predators, and harmless controls have been used to test host anti-parasitism defense behavior, and their ...

Quintuple parasitism of a great reed warbler nest by common cuckoos

open access: yesEcology 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

The limits of egg recognition: testing acceptance thresholds of American robins in response to decreasingly egg-shaped objects in the nest [PDF]

open access: yesRoyal Society Open Science, 2021
Some hosts of avian brood parasites reduce or eliminate the costs of parasitism by removing foreign eggs from the nest (rejecter hosts). In turn, even acceptor hosts typically remove most non-egg-shaped objects from the nest, including broken shells ...

Coevolution of acoustical communication between obligate avian brood parasites and their hosts

open access: yesAvian Research, 2020
The mutually antagonistic processes producing adaptations and counter-adaptations in avian brood parasites and their hosts provide a model system for the study of coevolution; this topic has long been an area of focus in ornithology and evolutionary ...

Coevolution in action: disruptive selection on egg colour in an avian brood parasite and its host. [PDF]

open access: yesPLoS ONE, 2010
Trait polymorphism can evolve as a consequence of frequency-dependent selection. Coevolutionary interactions between hosts and parasites may lead to selection on both to evolve extreme phenotypes deviating from the norm, through disruptive selection.Here,

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

open access: yesFrontiers 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.

Common cuckoo females remove more conspicuous eggs during parasitism [PDF]

open access: yesRoyal Society Open Science, 2021
Avian obligate brood parasites gain an advantage by removing the eggs of the cuckoos who have already visited the nest, which can increase the chances of survival for their offspring.
