Breeding stages affect egg recognition in azure-winged magpies (Cyanopica cyanus) [PDF]

open access: yesAnimal Cognition
Egg 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]

open access: yesEcology and Evolution
Egg recognition and rejection constitute essential host defenses against brood parasitism, with rejection decisions reflecting evolutionary adaptations shaped by cost–benefit trade‐offs.

Innate and learned components of egg recognition in the ant Camponotus floridanus [PDF]

open access: yesRoyal Society Open Science
Insect 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

Recognition and utilization of egg maculation signals by two sympatric host species

open access: yesJournal of Avian Biology
Egg color polymorphism and egg mimicry are important adaptations in the game process between hosts and brood parasites at the egg stage. The ability of hosts to recognize and reject parasitic eggs based on effective egg characteristics is a crucial ...

Clutch Destruction by Common Cuckoos (Cuculus canorus) During the Laying Stage of Vinous‐Throated Parrotbills (Sinosuthora webbiana): First Video Evidence [PDF]

open access: yesEcology and Evolution
Brood 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.

Recognition and rejection of foreign eggs of different colors in Barn Swallows

open access: yesAvian Research
Brood parasitic birds lay eggs in the nests of other birds, and the parasitized hosts can reduce the cost of raising unrelated offspring through the recognition of parasitic eggs.

Egg recognition and nestling discrimination in the Crested Myna (Acridotheres cristatellus): Size matters

open access: yesAvian Research, 2023
Most studies exploring abilities of hosts to detect brood parasitism are based on detecting colour and/or pattern differences among parasitic and host eggs or nestlings, while only few were focused on size differences. True recognition and recognition by

Research on image recognition of cracked eggs based on convolutional neural network model

open access: yesShipin yu jixie, 2023
Objective: In order to improve the accuracy and operating efficiency of the egg crack detection method based on computer vision. Methods: Used poultry egg simulation impact equipment to obtain cracked eggs, and collected images of cracked eggs and intact
