Female and male rufous horneros eject shiny cowbird eggs using a mental template of the size of their own eggs
(Elsevier Science, 2020-09)
Hosts of interspecific brood parasites often evolve antiparasitic defences, like the recognition and rejection of parasite's eggs. Most hosts use differences in coloration and maculation to discriminate between their own ...
Decision rules for egg recognition are related to functional roles and chemical cues in the queenless ant Dinoponera quadriceps
The capacity to distinguish colony members from strangers is a key component in social life. In social insects, this extends to the brood and involves discrimination of queen eggs. Chemical substances communicate colony ...
Variation in multicomponent recognition cues alters egg rejection decisions: A test of the optimal acceptance threshold hypothesis
(The Royal Society, 2019-04)
The optimal acceptance threshold hypothesis provides a general predictive framework for testing behavioural responses to discrimination challenges. Decision-makers should respond to a stimulus when the perceived difference ...
Brown-and-yellow marshbirds reduce their acceptance threshold of mimetic brood parasite eggs in the presence of non-mimetic eggs
(Springer Tokyo, 2016-01)
The recognition and subsequent rejection of brood parasite eggs is one of the most commonly observed defensive behaviors of the host. The brown-and-yellow marshbird (Pseudoleistes virescens) is a common host of the shiny ...
Red-crested Cardinals use color and width as cues to reject Shiny Cowbird eggs
(American Ornithologists' Union, 2016-04)
Como parte del proceso coevolutivo entre los parásitos de cría y sus hospedadores, estos últimos han desarrollado diferentes estrategias para discriminar y rechazar los huevos parásitos. Este proceso de reconocimiento y ...

Parasitic egg rejection decisions of chalk-browed mockingbirds Mimus saturninus are independent of clutch composition
(Springer Heidelberg, 2018-03)
Obligate avian brood parasites lay their eggs in nests of other host species, which assume all the costs of parental care for the foreign eggs and chicks. The most common defensive response to parasitism is the rejection ...
Discrimination of offspring by indirect recognition in an egg-feeding dendrobatid frog, Oophaga pumilio
Offspring discrimination, the differential treatment of offspring and unrelated young, functions in numerous animal taxa to ensure that vital and costly parental care behaviours are appropriately directed. Discrimination ...
