Nocturnal migratory flight initiation in reed warblers Acrocephalus scirpaceus : effect of wind on orientation and timing of migration [PDF]

open access: yesJournal of Avian Biology, 2002
We used radio‐telemetry to study autumn migratory flight initiation and orientation in relation to wind and air pressure in a nocturnal passerine migrant, the reed warbler Acrocephalus scirpaceus at Falsterbo, southwest Sweden.

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 ...

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 ...

Sedimentación de paseriformes palustres escasos durante el paso migratorio posnupcial en Txingudi (Euskadi) [PDF]

open access: yesMunibe Ciencias Naturales
El estuario de Txingudi, en el Cantábrico oriental, es un punto clave de parada migratoria de aves palustres, que son particularmente interesantes desde un punto de vista de la conservación dada su dependencia por ambientes muy específicos, que las hace ...

Oriental reed warbler (Acrocephalus orientalis) nest defence behaviour towards brood parasites and nest predators

open access: yesBehaviour, 2015
Brood parasites and predators pose different threats to passerines that may favour the evolution of enemy-specific defence strategies. Furthermore, potential sex-specific variation in parental investment may be manifested in differences between male and female nest defence behaviour.

Male song repertoire size and syllable sharing of oriental great reed warblers, acrocephalus orientalis

open access: yesAnimal Cells and Systems, 2009
Abstract The size of song repertoires mainly provides evidence for explaining sexual selection for female choice as well as male‐male competition. We investigated the role of oriental great reed warbler songs (Acrocephalus orientalis) of breeding territorial males.

Complete egg clutches as memory template for host egg recognition

open access: yesJournal of Avian Biology, Volume 2026, Issue 5, September 2026.
Egg recognition and rejection are among the most prevalent forms of host defense against brood parasitism. However, there is a lack of comprehensive data on the ability of hosts to update and modify their egg rejection strategy throughout the breeding cycle.

Hawk mimicry does not reduce attacks of cuckoos by highly aggressive hosts

open access: yesAvian Research, 2018
Background Resemblance to raptors such as hawks (Accipiter spp.) is considered to be an adaptive strategy of cuckoos (Cuculus spp.), which has evolved to protect cuckoos against host attacks.

Divergent Egg‐Rejection Strategies Between Laying and Incubation Periods in the Green‐Backed Tit (Parus monticolus)

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Our results demonstrate that green‐backed tits have evolved independent adaptive responses to distinct selective pressures: nest predation during egg‐laying and brood parasitism during incubation. This study provides new insights into the plasticity of host defenses and suggests that species with egg‐covering behaviors may develop specialized anti ...
