Stable isotope profile of autumnal migratory bird feathers on Italian Alps
<p>In the study of migration of birds, there are many aspects to be deepened to comprehend both ecology of the species and their geographical connectivity between breeding and wintering grounds. In the last decades, stable isotopes of light elements such as hydrogen, oxygen, nitrogen, carbon and sulphur measured in cheratinous tissues such feathers are increasingly used in order to delineate origin of migrants and to define ecological aspects of birds. Here we present a complete isotopic profile of several passerine species migrating through Italian Alps during post-breeding season. Stable isotope ratios of hydrogen, oxygen, carbon, nitrogen and sulphur were measured in juvenile feathers of 807 individuals of 48 different specie ringed in central Italian Alps during post-breeding migration in the years 2010, 2011, 2012, and 2013. Birds were ringed in two ringing and monitoring stations of Progetto Alpi (<a href="http://progetto-alpi.muse.it/">http://progetto-alpi.muse.it/</a>). No birds were mistreated, and the sampling took place in compliance with the national and international laws in force at the time of the study.</p>

Data from: A longitudinal analysis of the growth rate and mass of tail feathers in a great tit population: ontogeny, genetic effects and relationship between traits
<p class="MsoNoSpacing">Feathers have a diversity of functions in birds and are costly to produce, so their growth rate and mass can be reliable indicators of nutritional condition at the time of production. Despite the potential for feather metrics to advance our understanding of foraging, they are underused in avian ecology. One reason for this is the difficulty of interpreting whether individual variation is driven by ontogenetic, genetic, or environmental effects, which is exacerbated by the fact that most analyses have been done on cross-sectional data. We addressed this deficit using a longitudinal dataset of tail feathers collected from Great tits <em>Parus major</em> to test for ontogenetic and genetic effects on growth rate, mass and length, while controlling for body/feather size differences and other confounding factors. First, we found that the type of moult episode and experimentally-induced replacement differentially affected the length, mass and growth of feathers, providing evidence of an ontogenetic effect that should be considered when comparing these feather traits across individuals as a measure of condition. Second, we detected moderate to high repeatability and heritability values from parent-offspring regression for these three feather traits, which are suggestive of an underlying genetic component of variation. Third, we used a mean centring within-individual approach to test whether feather growth rate and feather mass (length-corrected) are indeed positively correlated with each other as overlapping indicators of body condition in birds, and found that this association, although positive, is weak and only significant between individuals. This suggests that both metrics are not so intimately linked as originally thought, and probably have different sensitivities to variation in foraging performance and ecological conditions. Together with the higher plasticity of feather growth rate compared to feather mass, our results support the idea that feather growth rate is better suited for examining short-term responses to environmental variation.</p>
Comparative analysis of passerine feather traits: data and script
<p></p> <p class="Normln1"><span>Tropical bird species are characterised by a comparatively slow pace of life, being predictably different from their temperate zone counterparts in their investments in growth, survival and reproduction. In birds, <span>the development of functional plumage is often considered energetically demanding investment, with consequences on individual fitness and survival. However, </span>current knowledge of interspecific variation in feather growth patterns is mostly based on species of the northern temperate zone. We<span> evaluated patterns in tail feather growth rates (FGR) and feather quality (</span>stress-induced <span>fault bar occurrence; FBO), </span>using<span> </span>1518 individuals of 167 species and 39 passerine families inhabiting Afrotropical and northern temperate zones. We <span>detected</span> a clear difference in feather traits between species breeding in the temperate and tropical zones, with the latter having significantly slower FGR and three times higher FBO. Moreover, trans-Saharan latitudinal migrants resembled temperate zone residents in that they exhibited a comparatively fast FGR and low FBO, despite sharing moulting environments with tropical species. Our results reveal convergent latitudinal shifts in feather growth investments (latitudinal syndrome) across unrelated passerine families and underscore the importance of breeding latitude in determining cross-species variation in key avian life-history traits.</span></p>

Data from: White plumage color as an honest indicator: feather macrostructure links reflectance with reproductive effort and success
<p class="normal1">The structural condition of feathers may generally have a decisive role in shaping the color properties of the plumage. However, the information content of structurally mediated color differences is poorly known. This makes it particularly hard to determine the meaning of color variation in pigment-free white plumage patches. The white wing patch of the collared flycatcher (<em>Ficedula albicollis</em>) is an important sexual trait, and changes in its reflectance are partly due to macrostructural condition. We used two years of macrostructural, reflectance and breeding data from both sexes to examine whether wing patch macrostructure lends information content to actual reflectance in terms of reproductive effort and success. Macrostructure strongly predicted actual reflectance in males but only weakly in females. Furthermore, in males, feather vane width was related positively to current year reproductive effort, and negatively to previous year reproductive effort. This indicates that macrostructurally mediated reflectance attributes may inform the receiver not only of actual reproductive capacity but also of individual quality via reproductive costs.</p>
The color of greater flamingo feathers fades when no cosmetics are applied
<p>Greater flamingos use cosmetic coloration by spreading uropygial secretions pigmented with carotenoids over their feathers, which makes the plumage redder. Because flamingos inhabit open environments that receive direct solar radiation during daytime, and carotenoids bleach when exposed to solar radiation, we expected that the plumage color would fade if there is no maintenance for cosmetic purposes. Here, we show that the concentrations of pigments inside feathers and on the surface of feathers were correlated, as well as that there was a correlation between the concentrations of pigments in the uropygial secretions and on the surface of feathers. There was fading in color (becoming less red) in feathers that received direct solar radiation when there was no plumage maintenance, but not so in others maintained in darkness. When we controlled for the initial color of feathers, the feathers of those individuals with higher concentration of pigments on the feather surfaces were those that lost less coloration after experimental exposure of feathers to sunny conditions. These results indicate that exposure to sunlight is correlated with the fading of feather color, which suggests that individuals need to regularly apply make-up to be more colorful. These results also reinforce the view that these birds use cosmetic coloration as a signal amplifier of plumage color. This may be important in species using highly variable habitats, such as wetlands, since the conditions experienced when molting may differ from those when the signal should be functional, usually months after molting.</p>
