Naïve hosts of avian brood parasites accept foreign eggs, whereas older hosts fine-tune foreign egg discrimination during laying [PDF]

open access: yes, 2014
BACKGROUND: Many potential hosts of social parasites recognize and reject foreign intruders, and reduce or altogether escape the negative impacts of parasitism.

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

open access: yesFrontiers 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.

Egg-spot matching in common cuckoo parasitism of the oriental reed warbler: effects of host nest availability and egg rejection [PDF]

open access: yesAvian Research, 2016
The success of cuckoo parasitism is thought to depend largely on the extent of egg matching between cuckoo and host eggs, since poor-matching cuckoo egg would lead to more frequent egg rejection by the host. In this study, we investigated how egg-spot matching between the Common Cuckoo (Cuculus canorus) and its host, the Oriental Reed Warbler ...

Warblers perform less nest defense behavior and alarm calls to human intruders: A result of habituation

open access: yesGlobal Ecology and Conservation, 2020
Human disturbance is caused by the anthropogenic activities in the environment. While human threat to wildlife is considered to be complex (nonlethal recreations and lethal hunting activities).

Do common cuckoos (Cuculus canorus) possess an optimal laying behaviour to match their own egg phenotype to that of their Oriental reed warbler (Acrocephalus orientalis) hosts? [PDF]

open access: yesBiological Journal of the Linnean Society, 2015
Received 20 June 2015; revised 6 August 2015; accepted for publication 7 August 2015Optimality theory suggests that parasitic cuckoos should evolve an optimal laying behaviour aiming to positivelyselect host nests in which the eggs match the phenotype of their own eggs, thus minimizing the rejection riskfrom hosts and, in turn, maximizing the cuckoos ...

Cryptic Hybridization Dynamics in a Three-Way Hybrid Zone of Dinopium Flamebacks on a Tropical Island. [PDF]

open access: yesEcol Evol
This study explores population divergence and hybridization dynamics across the golden‐backed (Dinopium benghalense) and red‐backed (D. psarodes) flameback woodpecker hybrid zone in Sri Lanka. The genomic analysis uncovers three‐way hybridization among two D. benghalense populations in the north and one island‐endemic D.

Market surveys in Mataram, Lombok, illustrate the expanse of legal and illegal Indonesian bird trade networks [PDF]

open access: yes, 2022
Bird keeping is deeply rooted in Indonesian culture and markets selling large numbers of birds are found across the country. We examined bird markets in Mataram on the island of Lombok. Across five market visits, 10,326 birds of 108 species were observed,
