Egg rejection and egg recognition mechanisms in Oriental Reed Warblers [PDF]
Avian Research, 2021 Background Nest parasitism by cuckoos (Cuculus spp.) results in enormous reproductive failure and forces hosts to evolve antiparasitic strategies, i.e., recognition of own eggs and rejection of cuckoo eggs.

A Meta-Analysis of Avian Egg Traits Cueing Egg-Rejection Defenses Against Brood Parasitism [PDF]
Frontiers in Ecology and Evolution, 2021 The capability of hosts to reject the odd egg from their nest is one of the key defenses against avian brood parasitism. Considerable research effort has been devoted to exploring which phenotypic traits of eggshells facilitate to cue the recognition of ...

Analysis of Egg Variation and Foreign Egg Rejection in Rüppell’s Weaver (Ploceus galbula) [PDF]
Frontiers in Ecology and Evolution, 2021 Egg appearance is notable for its variation and as a source of recognition cues in bird species that are subject to egg-mimicking brood parasitism. Here I analyze the egg appearance of an East African weaverbird species that has variable eggs and is a ...

Breeding stages affect egg recognition in azure-winged magpies (Cyanopica cyanus) [PDF]
Animal CognitionEgg rejection often involves a cognitive process of recognizing foreign eggs, which can vary not only between species or among different individuals of the same species, but also within the same individual during different breeding stages, leading to ...

Egg Spots Are Important Cues for Egg Recognition in Barn Swallows [PDF]
Ecology and EvolutionEgg 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 ...

Visual complexity of egg patterns predicts egg rejection according to Weber's law. [PDF]
Proc Biol Sci, 2022 Visual complexity is ubiquitous in nature. Drivers of complexity include selection in coevolutionary arms races between antagonists. However, the causes and consequences of biological complexity and its perception are largely understudied, partly because complexity is difficult to quantify.

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 ...

Categorical identity signatures can reduce host error rates during brood parasitism. [PDF]
PLoS BiologyBiological recognition is often modeled as involving discrimination of continuously-distributed (and continuously-perceived) traits according to decision thresholds. However, traits such as animal signals can be categorically distributed.

Egg rejection based on egg size recognition as a specific strategy against parasitic cuckoos. [PDF]
Curr Zool, 2023 Abstract In the coevolutionary interactions between avian brood parasites and their hosts, egg recognition based on color and/or pattern is a common and effective defense to counter parasitism. However, for egg recognition based on size, only a few studies have found affirmative results, and they do not provide unambiguous evidence that ...

Does nest sanitation elicit egg rejection in an open-cup nesting cuckoo host rejecter? [PDF]
Avian Research, 2018 Background Nest sanitation behavior is one of the most important means to ensure high reproductive efficiency. In avian brood parasitism, nest sanitation behavior may be a pre-adaptation of host birds that allows them to identify the parasitic eggs, so ...
