Abstract As urbanization expands, so does the presence of anthropogenic materials within bird’s nests. However, our understanding this phenomenon remains limited, particularly in terrestrial birds. This study describes and compares use great tit ( Parus major ) blue Cyanistes caeruleus nests relation to intensity activities, distance contamination sources reproductive metrics, nest boxes a suburban wood Coimbra, Portugal, during breeding seasons 2020 2021. Nests were collected after fledging...
Mediterranean woodland environments are characterised by high spatial and temporal heterogeneity, which means the inhabiting species face a wide variety of selective pressures. Species may respond differently to habitat heterogeneity so distinct eco-evolutionary scenarios be responsible for inter-habitat variability in reproductive strategies observed certain species. The inter-forest some traits passerines has been examined comparing forest patches or separated fragments. However, there is...
Several ectoparasites parasitise nestlings decreasing their body condition, growth and survival. To minimise any loss of fitness due to ectoparasites, birds have developed a wide variety defence mechanisms, potentially including hatching asynchrony. According the Tasty Chick Hypothesis (TCH), cost parasitism would be reduced if tend eat on less immunocompetent nestlings, typically last-hatched chick in asynchronously hatched broods, as they are poor condition. Two predictions TCH that immune...
Genetic differentiation between populations inhabiting ecologically different habitats might appear because of limited dispersal and gene flow, which may lead to patterns phenotypic divergence local adaptation. In this study, we use dispersal, genotypic (24 microsatellite loci) (body size clutch size) data analyse genetic structuring in a blue tit ( Cyanistes caeruleus ) population continuous heterogeneous woodland along valley. The two slopes the valley differ their forest formations...
Abstract The utility of fresh green material in avian nests is still not fully understood. Potential explanations include the effects plants’ volatile compounds on parasite reduction (nest protection hypothesis) or direct beneficial nestling condition (drug hypothesis). We used correlative data collected during 2020 and 2021 a Mediterranean population blue tits ( Cyanistes caeruleus ) as well experimental (aromatic nest content manipulation) to assess aromatic plant use physiological...

Wild birds are hosts of Culicoides from as early on the nesting stage when constrained to their nests. However, environmental factors which determine abundance and composition species within each bird nest still understudied. We sampled Eurasian blue tit (Cyanistes caeruleus) nests found in 2 types forests located southern Spain. Firstly, we monitored a dry Pyrenean oak deciduous forest humid mixed comprising Holm oaks throughout consecutive years. During 3rd year, performed cross-fostering...
Heritable microbes that exhibit reproductive parasitism are common in insects. One class of these the male-killing bacteria, which found a broad range insect hosts. Commonly, our knowledge incidence is based on one or few sampling sites, and degree causes spatial variation unclear. In this paper, we examine son-killer microbe Arsenophonus nasoniae across European populations its wasp host, Nasonia vitripennis. preliminary work, noticed two female N. vitripennis producing highly biased sex...
Filarioid nematodes (commonly known as filarial worms) are to impact human and domestic animal health, but studies examining their ecological relevance impacts on wildlife still underrepresented. In the case of birds, microfilariae typically found at low prevalence, they may negatively affect some fitness-related traits. Here, we study prevalence associations in a wild population blue tits (Cyanistes caeruleus) inhabiting woodland comprising different forestry formations. addition,...
Abstract Nestlings normally exhibit a mix of traits that attract parental care, such as postural and vocal begging carotenoid‐based mouth colouration. These signals are hypothesised to be signs nestling needs (vocal begging) quality (mouth colouration). Therefore, we broods, where nestlings beg for less time display more saturated colouration, would have lower mortality. We tested these predictions in two wild blue tit ( Cyanistes caeruleus ) populations. The breeding success (here defined...

Abstract Parasites impact host fitness and constitute an important selective pressure on the host's life history. According to parasite‐mediated sexual selection, ornaments are presumed honestly indicate immune capacity or resistance against parasites, chooser sex (typically females) obtains advantage by selecting more ornamented, thus immunocompetent mates. Therefore, signalers mounting response must allocate resources from signal system, hence reducing expression of ornament becoming less...
The diets of the Barn Owl Tyto alba and Short-eared Asio flammeus have been extensively studied worldwide over past few years, especially on Iberian Peninsula. Nevertheless, very studies examined trophic niche overlap in areas where these two raptor species occur sympatry. As such, this study we compared inhabiting agricultural landscapes Vega de Granada, south-east Spain, based pellet analysis. were similar, as both owls preyed mainly small mammals, Algerian Mouse Mus spretus being prey...
Mixed-species broods appear to be an uncommon phenomenon in altricial birds. In secondary hole-nesting birds, such as tits (Paridae), mixed-species clutches occur a consequence of facultative interspecific brood parasitism or byproduct nest takeover. Here, we report case composed one Coal Tit Periparus ater and three Blue Cyanistes caeruleus nestlings that was successfully raised by pair. The foreign nestling received more food than its nestmates, possibly resulting larger tarsus length...
Avian growth has been traditionally examined using logistic, Gompertz or von Bertalanffy non-linear equations. Although many studies have analysed nestling mass increase and the factors affecting rates, there is little information on curves for several avian groups, such as Nuthatches (Sittidae). Moreover, breeding biology of still poorly studied because their reluctance to use nest boxes. Here we pattern in Eurasian Nuthatch Sitta europaea nestlings, addition studying this species, a mixed...
