Oriental reed warblers retain strong egg recognition abilities during the nestling stage [PDF]
Ecology and EvolutionEgg 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.

Probing the Limits of Egg Recognition Using Egg Rejection Experiments Along Phenotypic Gradients. [PDF]
J Vis Exp, 2018 Brood parasites lay their eggs in other females' nests, leaving the host parents to hatch and rear their young. Studying how brood parasites manipulate hosts into raising their young and how hosts detect parasitism provide important insights in the field of coevolutionary biology.

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 ...

Divergent Egg‐Rejection Strategies Between Laying and Incubation Periods in the Green‐Backed Tit (Parus monticolus) [PDF]
Ecology and EvolutionEgg recognition and rejection constitute essential host defenses against brood parasitism, with rejection decisions reflecting evolutionary adaptations shaped by cost–benefit trade‐offs.

Clutch Destruction by Common Cuckoos (Cuculus canorus) During the Laying Stage of Vinous‐Throated Parrotbills (Sinosuthora webbiana): First Video Evidence [PDF]
Ecology and EvolutionBrood parasitism by the Common Cuckoo (Cuculus canorus) depends on precise timing, with females typically laying during the host's laying phase to ensure their chick hatches first.

How Do Oriental Reed Warblers Recognize Cuckoo Eggs? [PDF]
Ecology and EvolutionOriental reed warblers (Acrocephalus orientalis) are favorite hosts of common cuckoos (Cuculus canorus). However, the cognitive basis and underlying mechanisms of the host egg discrimination behavior remain not well understood.

Innate and learned components of egg recognition in the ant Camponotus floridanus [PDF]
Royal Society Open ScienceInsect societies discriminate against foreigners to avoid exploitation. In ants, helper workers only accept individuals with the familiar chemical cues of their colony. Similarly, unfamiliar eggs may get rejected at their first appearance in the nest. We

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.
