Large hawk-cuckoo Hierococcyx sparveroides parasitism on the Chinese babax Babax lanceolatus may be an evolutionary recent host-parasite system
Yang, Canchao; Antonov, Anton Tinchov; Cai, Yan; Stokke, Bård Gunnar; Moksnes, Arne; Røskaft, Eivin; Liang, Wei (Journal article; Peer reviewed, 2012)We documented brood parasitism by the poorly studied Large Hawk-Cuckoo on a previously unknown host species, the Chinese Babax. Furthermore, we describe a new egg colour for the Large Hawk-Cuckoo. The parasitism rate of ... -
Modelling the maintenance of egg polymorphism in avian brood parasites and their hosts
Liang, Wei; Yang, Canchao; Stokke, Bård Gunnar; Antonov, Anton Tinchov; Fossøy, Frode; Vikan, Johan Reinert; Moksnes, Arne; Røskaft, Eivin; Shykoff, Jacqui A.; Møller, Anders Pape; Takasu, Fugo (Journal article, 2012)In avian brood parasitism, egg phenotype plays a key role for both host and parasite reproduction. Several parrotbill species of the genus Paradoxornis are parasitized by the common cuckoo Cuculus canorus, and clear ... -

Outcomes of brood parasite-host interactions mediated by egg matching: Common cuckoos Cuculus canorus versus Fringilla finches
Vikan, Johan Reinert; Fossøy, Frode; Huhta, Esa; Moksnes, Arne; Røskaft, Eivin; Stokke, Bård Gunnar (Journal article; Peer reviewed, 2011)Background: Antagonistic species often interact via matching of phenotypes, and interactions between brood parasitic common cuckoos (Cuculus canorus) and their hosts constitute classic examples. The outcome of a parasitic ... -
Reject the odd egg: Egg recognition mechanisms in parrotbills
Yang, Canchao; Møller, Anders Pape; Røskaft, Eivin; Moksnes, Arne; Liang, Wei; Stokke, Bård Gunnar (Journal article; Peer reviewed, 2014)Studies of the behavior of animals when confronted with tasks differing in complexity can improve our understanding of animal cognition and learning mechanisms. Coevolutionary interactions between brood parasites and their ... -
Resident bird species track inter-annual variation in spring phenology better than long-distance migrants in a subalpine habitat
Søraker, Jørgen Skavdal; Stokke, Bård Gunnar; Kleven, Oddmund; Moksnes, Arne; Rudolfsen, Geir; Skjærvø, Gine Roll; Vaagland, Henriette; Røskaft, Eivin; Ranke, Peter Sjolte (Journal article; Peer reviewed, 2022) -
Reviewing 30 years of studies on the Common Cuckoo - accumulated knowledge and future perspectives
Moksnes, Arne; Fossøy, Frode; Røskaft, Eivin; Stokke, Bård Gunnar (Journal article, 2013)In Europe, eggs of the Common Cuckoo (Cuculus canorus) have been found in more than 125 different host species. However, very few species are frequently parasitized. The Cuckoo is divided into several distinct races termed ... -
Sex Allocation in Relation to Host Races in the Brood-Parasitic Common Cuckoo (Cuculus canorus)
Fossøy, Frode; Moksnes, Arne; Røskaft, Eivin; Antonov, Anton Tinchov; Dyrcz, Andrzej; Moskát, Csaba; Ranke, Peter Sjolte; Rutila, Jarkko; Vikan, Johan Reinert; Stokke, Bård Gunnar (Journal article; Peer reviewed, 2012)Sex allocation theory and empirical evidence both suggest that natural selection should favour maternal control of offspring sex ratio in relation to their ability to invest in the offspring. Generalist parasites constitute ... -
Sex roles in egg recognition and egg polymorphism in avian brood parasitism
Liang, Wei; Yang, Canchao; Antonov, Anton Tinchov; Fossøy, Frode; Stokke, Bård Gunnar; Moksnes, Arne; Røskaft, Eivin; Shykoff, Jacqui A.; Møller, Anders Pape; Takasu, Fugo (Journal article, 2012)Avian brood parasites impose strong selection on their hosts leading to the evolution of antiparasite defenses like egg recognition and rejection. Discordance and template-based cognitive mechanisms may form the base for ... -
Undersøkelser av fuglefaunaen og småviltbestanden i de områdene som blir berørt av planene om kraftutbygging i Garbergelva, Rotla og Torsbjørka

UV reflectance as a cue in egg discrimination in two Prinia species exploited differently by brood parasites in Taiwan
Yang, Canchao; Wang, Longwu; Hsu, Yu-Cheng; Antonov, Anton Tinchov; Moksnes, Arne; Røskaft, Eivin; Liang, Wei; Stokke, Bård Gunnar (Journal article, 2013)Birds are capable of seeing the ultraviolet light (UV) spectrum and as a consequence have evolved UV-reflective structures with signalling functions. Avian eggs also reflect in the UV spectrum but the importance of UV egg ... -

Why do brood parasitic birds lay strong-shelled eggs?
Antonov, Anton Tinchov; Stokke, Bård Gunnar; Fossøy, Frode; Liang, Wei; Moksnes, Arne; Røskaft, Eivin; Yang, Canchao; Møller, Anders Pape (Journal article, 2012)Brood parasitic birds constitute a model system for the study of coevolution. Such parasites are unique by having evolved unusually thick eggshells for their body size. Thick eggshells have been hypothesized to evolve as ...
