Soler, AuteurIntraspecific brood parasitism is widespread among birds and provides clues for elucidating the evolutionary origin of interspecific brood parasitism. Studies suggest that brood parasitism does not occur at random, but that parasitic females sel[...]

Vásquez, Auteur ; Alexandra Kuchar, Auteur ; Erich Moestl, Auteur ; Jose Luis Osorno, AuteurGlucocorticoids promote the mobilization of energy stores and they may facilitate the expression of energetically expensive functions. Early arrival on the breeding grounds in migratory species and territorial competition are energetically deman[...]

Jose L. Osorno, Auteur ; Judith Morales, Auteur ; Juan Moreno, Auteur ; Santiago Merino, Auteur ; Gustavo Tomás, Auteur ; Rodrigo A. Vásquez, AuteurWe present evidence of differential maternal allocation to eggs in response to manipulated male attractiveness in the migratory pied flycatcher (Ficedula hypoleuca). We manipulated the size of a male secondary sexual trait, the white forehead pa[...]
