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

Beyond genes‐for‐behaviour: The potential for genomics to resolve long‐standing questions in avian brood parasitism [PDF]
Behavioural ecology by definition of its founding ‘Tinbergian framework’ is an integrative field, however, it lags behind in incorporating genomic methods. ‘Finding the gene/s for a behaviour’ is still rarely feasible or cost‐effective in the wild but as

Video evidence that cuckoos farm their hosts by ejecting nestlings [PDF]
When host nests are scarce, avian brood parasites would benefit from behaviours that increase the availability of suitable nests. Several studies reported ejection of host nestlings from nests by brood parasites; however, whether brood parasites do so to

Egg Retrieval as a Cognitive Indicator in Cuckoo Hosts [PDF]
Egg 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 ...

Asian koel rapidly locates host breeding in novel nest sites [PDF]
Avian brood parasites depend upon locating host nests to lay their eggs. However, how brood parasites locate host nests and select the nests for parasitism remains poorly studied.

Lifetime expression of egg rejection behaviour in Eurasian magpies is associated with variation in a polymorphic genetic marker [PDF]
Obligate avian brood parasitism is a reproductive strategy in which parasitic birds rely entirely on host species for incubation and chick rearing, reducing host reproductive success.

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

Living and/or non-living animal models are often used as stimuli to observe the behavioral responses of the target animals. In the past, parasites, predators, and harmless controls have been used to test host anti-parasitism defense behavior, and their ...

The limits of egg recognition: testing acceptance thresholds of American robins in response to decreasingly egg-shaped objects in the nest [PDF]
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 ...

Quintuple parasitism of a great reed warbler nest by common cuckoos
Multiple parasitism in obligate avian brood parasites occurs when several brood parasitic females lay their eggs in the nest of the same host. While multiple parasitism is common in the highly social, nonevicting cowbird species (Molothrus sp.), in which
