Article
Philippe Fontanilles, Auteur ; Iván De la Hera, Auteur ; Kevin Sourdrille, Auteur ; Florent Lacoste, Auteur ; Christian Kerbiriou, AuteurWetlands are highly productive habitats used by many avian species as stopover sites during their migrations. However, these habitats are highly threatened by anthropogenic activities, such as land-use changes, the introduction of exotic species[...]
Article
Iván De la Hera, Auteur ; Javier Pérez-Tris, Auteur ; José Luis Tellería, AuteurThere is increasing evidence of adaptive preferential investment during moult in those feather tracts that are more advantageous for fitness. In this study, we assessed whether, after the manual removal of two functionally different flight feath[...]

Article
Iván De la Hera, Auteur ; Jose A. Diaz, Auteur ; Javier Pérez-Tris, Auteur ; José Luis Tellería, AuteurBirds moult to maintain plumage function through life, but the factors that determine moult duration are poorly understood. In temperate areas, variation in moult duration could be largely associated with between-species differences in migratory[...]
Article
Barbara M. Tomotani, Auteur ; Ezra Caglar, Auteur ; Iván De la Hera, Auteur ; A. Christa Mateman, Auteur ; Marcel E. Visser, AuteurWhen assessing the benefits of early arrival date of migratory birds, a hidden and often ignored component of males' fitness is the higher chance of early-arriving birds to obtain extra-pair fertilizations. Here we investigated how extra-pair pa[...]
Article
Iván De la Hera, Auteur ; Javier Pérez-Tris, Auteur ; Jose Luis Telleria, AuteurIn migratory species, the way in which conspecifics from different breeding populations are distributed during the non-breeding period is important from and ecological, evolutionary and conservation perspective, but such knowledge is still limit[...]
Article
Iván De la Hera, Auteur ; Francisco Pulido, Auteur ; Marcel E. Visser, AuteurIn migratory bird species, juveniles normally have shorter and more rounded wings than adults. The causes of this age-specific difference in wing morphology, however, are largely unknown. Here, we used longitudinal data collected over 3years fro[...]
Article
Jose Luis Telleria, Auteur ; Maria Blazquez, Auteur ; Iván De la Hera, Auteur ; Javier Pérez-Tris, AuteurWhen different populations of the same bird species share non-breeding habitats, competition for food may promote resource partitioning. We studied food choice by resident and migratory Blackcaps Sylvia atricapilla in sympatric wintering grounds[...]
Article
Iván De la Hera, Auteur ; Javier Pérez-Tris, Auteur ; José Luis Tellería, AuteurMoult is a costly but necessary process in avian life, which displays two main temporal patterns within the annual cycle of birds (summer and winter moult). Timing of moult can affect its duration and consequently the amount of material invested[...]
Article
Iván De la Hera, Auteur ; Anders Hedenstroem, Auteur ; Javier Pérez-Tris, Auteur ; José Luis Tellería, AuteurMigration causes temporal and energetic constraints during plumage development, which can compromise feather structure and function. In turn, given the importance of a good quality of flight feathers in migratory movements, selection may have fa[...]
