In socially monogamous birds, pair bond duration varies widely across species, from single-breeding associations to long-lasting, multi-year bonds. Studies on mate retention and divorce have predominantly focused long-lived while research in short-lived migratory species is limited. Consequently, the fitness consequences of or remating these remain unclear. Here, we used a long term (1987–2023) individual-based dataset investigate reproductive pied flycatchers (Ficedula hypoleuca),...
Many nocturnal animals, including invertebrates such as scorpions and a variety of vertebrate species, toadlets, flying squirrels, owls, nightjars, emit bright fluorescence under ultraviolet light. However, the ecological significance this unique coloration so attached to nocturnality remains obscure. Here, we used an intensively studied population migratory red-necked nightjars (Caprimulgus ruficollis) investigate inter-individual variation in porphyrin-based pink according sex, age, body...
Floaters are sexually mature individuals that not able to reproduce by defending breeding resources. often visit active nests, probably gather public information or compete for a nesting site. We tested the hypothesis floaters preferentially prospect nests in which they have better chance of taking over, and do so assessing owners' resource holding potential (RHP). manipulated flight capacity male female breeders population spotless starlings ( Sturnus unicolor ) clipping two feathers per...
Abstract Urbanization constitutes one of the major transformations natural habitats, creating new areas characterized by multiple potential wildlife stressors. Birds that live in highly anthropized zones are confronted with physiological and behavioural challenges caused these Here, we investigated if several health parameters differed between three subpopulations tree sparrow nestlings subjected to different levels anthropogenic pollution, particularly noise pollution: a quiet rural area,...
Floaters constitute the sexually mature but non-breeding part of populations. Despite being ubiquitous in most species, knowledge about floaters is scarce. Ignoring this significant number individuals may strongly bias our understanding population dynamics and sexual selection processes. We used spotless starling (Sturnus unicolor) to examine whether phenotypical non-phenotypical variables from early adult life predict reproductive status, focusing on earliest age at which start breed, when...
It has been proposed that blue‐green egg coloration is a condition‐dependent female sexual trait may modify paternal care in post‐mating selection scenario. This pattern arise because the pigment responsible for eggshell colouration (biliverdin) be costly and limited resource, whose availability linked to health state. Thus, it can predicted females condition compromised should constrained their capacity deposit biliverdin eggshell, thus producing paler clutches. To test this hypothesis, we...
