Barbara A. Caspers, Auteur ; Reinaldo Marfull, Auteur ; Tim Dannenhaus, Auteur ; Jan Komdeur, Auteur ; Peter Korsten, AuteurAcoustic and visual signals are well known to play important roles in social communication in birds. Growing evidence suggests that many bird species, including species of songbirds, additionally have a well-developed sense of smell. However, we[...]Article

Dugdale, AuteurDans Ibis (161(4) 2019)We used microsatellite DNA to assign probable parentage of young Corn Crakes to adult males and females and used these assignments to estimate the distribution of distances between broods of chicks and juveniles and the night-time singing place [...]Article
Seyed Mehdi Amininasab, Auteur ; Martje Birker, Auteur ; Sjouke A. Kingma, Auteur ; Hanno Hildenbrandt, Auteur ; Jan Komdeur, AuteurThe incubation of eggs plays a key role in avian parental care. To ensure embryo development, incubating parents have to keep their eggs within the appropriate temperature limits. To do so, incubating individuals allocate substantial energy to t[...]Article
Ralph Buij, Auteur ; Nikie Van Dorst, Auteur ; Henriette F. Salomons, Auteur ; Barbara M. Croes, Auteur ; Maurine W. Dietz, Auteur ; Jan Komdeur, AuteurAnthropogenic habitat alteration has probably contributed significantly to the decrease of raptor populations in West African savannas. To evaluate the impact of habitat degradation on foraging by sedentary Afrotropical raptors, we investigated [...]Article
Reinder Radersma, Auteur ; Jan Komdeur, Auteur ; Joost M. Tinbergen, AuteurA potential key event linking the nestling phase to first-year survival is fledging (nest leaving) because this process is characterized by a major change of environments and therefore a sudden shift in selective forces. Here we assessed whether[...]Article

Oscar Vedder, Auteur ; Sjouke-Anne Kingma, Auteur ; Nikolaus von Engelhardt, Auteur ; Peter Korsten, Auteur ; Ton G. G. Groothuis, Auteur ; Jan Komdeur, AuteurLaying eggs in nests of unrelated conspecific pairs to parasitize their parental care is a common phenomenon in birds. In blue tits Cyanistes caeruleus such conspecific brood parasitism (CBP) has never been reported in the literature. However, i[...]Article
Ben J. Koks, Auteur ; Christiane Trierweiler, Auteur ; Erik G. Visser, Auteur ; Cor Dijkstra, Auteur ; Jan Komdeur, AuteurLoss and degradation of habitat threatens many bird populations. Recent rural land-use changes in the Netherlands have led to a shift in habitat use by breeding Montagu's Harriers Circus pygargus. Since the 1990s, unprecedented numbers of this s[...]Article
Peter Santema, Auteur ; Simon C. Griffith, Auteur ; Naomi E. Langmore, Auteur ; Jan Komdeur, Auteur ; Michael J. L. Magrath, AuteurColonial breeding occurs in a wide range of taxa, however the advantages promoting its evolution and maintenance remain poorly understood. In many avian species, breeding colonies vary by several orders of magnitude and one approach to investiga[...]Article
Peter Korsten, Auteur ; Tobias Limbourg, Auteur ; Catherine M. Lessells, Auteur ; Jan Komdeur, AuteurUltraviolet (UV) plumage is thought to be sexually selected through intra-sexual competition, female choice and differential allocation. Experimental manipulations of plumage UV reflectance are essential to demonstrate that mate choice or intra-[...]Article
Ralph Buij, Auteur ; Ingrid Folkertsma, Auteur ; Kim Kortekaas, Auteur ; Hans H. De Iongh, Auteur ; Jan Komdeur, AuteurRaptor populations in Sudano-Sahelian West Africa are being severely affected by widespread habitat alteration which depletes prey populations, potentially aggravated by changing rainfall patterns. We studied Grasshopper Buzzards Butastur rufipe[...]Article
Mathew L. Berg, Auteur ; Nienke H. Beintema, Auteur ; Justin A. Welbergen, Auteur ; Jan Komdeur, AuteurThe vast majority of bird species build a nest in which to breed. Some species build more than one nest, but the function of most multiple nest-building remains unclear. Here we describe the unusual nest-building behaviour of the Australian Reed[...]Article
René E. van Dijk, Auteur ; Arjen E. Pilon, Auteur ; Istvan Szentirmai, Auteur ; Tamás Székely, Auteur ; Jan Komdeur, AuteurSpatial and temporal distributions of resources and habitats often influence breeding systems. These influences are particularly relevant in those species that exhibit variable breeding systems. We studied such a species, the Penduline Tit Remiz[...]Article
Ralph Buij, Auteur ; Dirk Van der Goes, Auteur ; Hans H. De Iongh, Auteur ; Sama Gagare, Auteur ; Patsy Haccou, Auteur ; Jan Komdeur, Auteur ; Geert De Snoo, AuteurThe floodplains of the West-African Sahel region have experienced extensive habitat transformation during the past four decades, coinciding with an impoverishment of raptor populations. We investigated foraging patterns of Palaearctic migratory [...]Article
Seyed Mehdi Amininasab, Auteur ; Martijn Hammers, Auteur ; Oscar Vedder, Auteur ; Jan Komdeur, Auteur ; Peter Korsten, AuteurStudies of age-specific reproductive performance are fundamental to our understanding of population dynamics and the evolution of life-history strategies. In species with bi-parental care, reproductive ageing trajectories of either parent may be[...]Article
René E. van Dijk, Auteur ; Jan Komdeur, Auteur ; Marco Van Der Velde, Auteur ; Istvan Szentirmai, Auteur ; Xutong Yang, Auteur ; Richard Ffrench-Constant, Auteur ; Tamás Székely, AuteurDespite the growing literature on facultative sex-ratio adjustment in chromosomal sex-determining vertebrate taxa (birds, mammals), the consistency of results is often low between studies and species. Here, we investigate the primary and seconda[...]Article
Ken Kraaijeveld, Auteur ; Ma Ming, Auteur ; Jan Komdeur, Auteur ; Raoul A. Mulder, AuteurIn sexually dichromatic birds, females may adaptively adjust the sex ratio of their offspring prior to hatching in relation to male ornamentation, for example, by producing more sons when paired to a highly attractive partner. However, to our kn[...]Article
Kees van Oers, Auteur ; David S. Richardson, Auteur ; Stein A. Saether, Auteur ; Jan Komdeur, AuteurAvian malaria can affect survival and reproduction of their hosts. Two patterns commonly observed in birds are that females have a higher prevalence of malaria than do males and that prevalence decreases with age. The mechanisms behind these pat[...]Article
