Timing pattern of Common Cuckoo parasitism and its relation to host nest attendance

Ibis, EarlyView.
Classical works show the adaptive importance of precise timing of egg‐laying in brood parasitic Common Cuckoos Cuculus canorus to ensure sufficient incubation time and successful hatching. Laying in the late afternoon has been suggested to increase the chance of secretive parasitism and therefore escape the aggressive mobbing by hosts, yet this ...

Successful Brood Parasitism of the Great Spotted Cuckoo on an Alternative Host Species Under Atypical Conditions

Diversity
Avian brood parasites occasionally interact with alternative hosts, providing valuable insights into their behavioral flexibility under atypical environmental conditions.

Egg rejection and clutch phenotype variation in the plain prinia Prinia inornata

Journal of Avian Biology, 2016
Avian hosts of brood parasites can evolve anti‐parasitic defenses to recognize and reject foreign eggs from their nests. Theory predicts that higher inter‐clutch and lower intra‐clutch variation in egg appearance facilitates hosts to detect parasitic ...

Is it best on the nest? Effects of avian life-history on haemosporidian parasitism

International Journal for Parasitology: Parasites and Wildlife, 2020
Infectious diseases vary in prevalence and pathology among host species. Species may differ in prevalence of infection due to varying exposure and susceptibility to disease agents throughout their lifetime, which may be attributable to underlying ...

Hatching failure and embryo mortality in endangered populations of Eurasian Curlew (Numenius arquata)

Ibis, EarlyView.
Hatching failure represents a significant and growing barrier to reproductive success in threatened birds and yet is often poorly understood. Populations of the Eurasian Curlew Numenius arquata in the United Kingdom and Republic of Ireland have experienced significant declines over recent decades, and low breeding productivity is a major barrier to ...

Age-related brood parasitism and egg rejection in magpie hosts [PDF]

, 2020
When the strength or nature of a host-parasite interaction changes over the host life cycle, the consequences of parasitism can depend on host population age structure. Avian brood parasites reduce hosts’ breeding success, and host age may play a role in

Egg pattern mimicry in avian brood parasitism assessed using local image descriptors and human-eyes

Egg pattern plays a critical role in avian brood parasitism where a brood parasite exploits a host's parental care by laying eggs in host nests relying on the host to rear the parasitic egg(s).

Common Cuckoo Nestling Adapts Its Begging Behavior to the Alarm Signaling System of a Host

Frontiers in Ecology and Evolution, 2022
Cuckoo nestlings thrive as avian brood parasites. To acquire sufficient food from the host parents, cuckoo nestlings generally make louder begging calls than host nestlings, but this may cause them to be more likely to attract the attention of predators.

Comparative Loss of Reproductive Potential Among Increased Clutch Sizes in Relation to Climate Change in a High Trophic Avian Predator: A 44‐Year Study

Journal of Zoology, EarlyView.
A North America, Wisconsin population of breeding Cooper's Hawks (Astur cooperii) is responding favorably to recent climate change with earlier egg‐laying and increased reproduction. But a 44‐year study demonstrated that tallies of older age offspring only at the nestling stage wouldunderestimate the comparatively higher loss of embryos and hatchlings ...

Modelling the maintenance of egg polymorphism in avian brood parasites and their hosts [PDF]

Journal of Evolutionary Biology, 2012
AbstractIn avian brood parasitism, egg phenotype plays a key role for both host and parasite reproduction. Several parrotbill species of the genusParadoxornisare parasitized by the common cuckooCuculus canorus, and clear polymorphism in egg phenotype is observed.
