Relationships between egg-recognition and egg-ejection in a grasp-ejector species. [PDF]

open access: yesPLoS ONE, 2017
Brood parasitism frequently leads to a total loss of host fitness, which selects for the evolution of defensive traits in host species. Experimental studies have demonstrated that recognition and rejection of the parasite egg is the most common and ...

Egg Spots Are Important Cues for Egg Recognition in Barn Swallows [PDF]

open access: yesEcology and Evolution
Egg recognition is one of the most common strategies utilized by host birds to combat brood parasitism. Eggshell surface features (e.g., eggshell color and spots) are important cues for host egg recognition, enabling avian hosts to recognize and reject ...

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 ...

Oriental reed warblers retain strong egg recognition abilities during the nestling stage [PDF]

open access: yesEcology and Evolution
Egg recognition and rejection are the most common and effective anti‐parasitic strategies against avian brood parasitism in terms of maintaining stability over time and plasticity in response to environmental cues.

Brood parasitism and egg recognition in three bunting hosts of the cuckoos [PDF]

open access: yesEcology and Evolution, 2023
Comparative studies of egg recognition and rejection between various sympatric hosts provide insight into the coevolutionary history of the hosts and parasites, as well as the degree of antagonism between the species.

Egg recognition: The importance of quantifying multiple repeatable features as visual identity signals. [PDF]

open access: yesPLoS ONE, 2021
Brood parasitized and/or colonial birds use egg features as visual identity signals, which allow parents to recognize their own eggs and avoid paying fitness costs of misdirecting their care to others' offspring.

Contrasting effects of egg size and appearance on egg recognition and rejection response by Oriental reed warblers [PDF]

open access: yesEcology and Evolution, 2020
Background Among potential hosts, the rejection of foreign eggs, which is a common and effective strategy to counter brood parasitism, depends on egg recognition.

Egg‐Inspection Frequency Predicts Egg Recognition but Not Ejection in a Cuckoo Host [PDF]

open access: yesEcology and Evolution
One 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.

Parasitic egg recognition using convolution and attention network [PDF]

open access: yesScientific Reports, 2023
Intestinal parasitic infections (IPIs) caused by protozoan and helminth parasites are among the most common infections in humans in low-and-middle-income countries. IPIs affect not only the health status of a country, but also the economic sector.

Model eggs fail to detect egg recognition in host populations after brood parasitism is relaxed [PDF]

open access: yesFrontiers in Zoology, 2020
Background Obligate brood parasites exert strong selective pressure on target hosts. In response, hosts typically evolve anti-parasitism strategies, of which egg recognition is one of the most efficient.
