“…We described aspects of the migratory habits of two passerines at an important stage and location of their life cycle using a combined multi stable-isotope and ring recovery approach. We demonstrated the effectiveness of combining the use of d 2 H f and ringing data to track migratory flyways in the Western Palaearctic (Proch azka et al 2013, Cardador et al 2014, Guillemain et al 2014. We further assessed the potential of spatial and habitat information that d 13 C f , d 15 N f and d 34 S f may contribute to the assignment model using a multi-isotope approach for European breeding birds.…”

Understanding spatial linkages between areas used by migratory animals during the annual cycle is fundamental to their conservation. Stable isotope measurements of animal tissues can be a valuable tool in understanding spatial connectivity and migration phenology of migratory wildlife. We inferred natal origins of two migratory passerines, European Pied Flycatcher Ficedula hypoleuca and European Robin Erithacus rubecula, captured during autumn migration in the Italian Alps, by combining feather δ2H (δ2Hf) and ring recovery data. We used a spatially explicit likelihood‐based method to assign individuals to a precipitation δ2H surface calibrated to represent feather δ2H, together with the directional probability of origin from ring recoveries. The highest probabilities of origin for most individuals of both species were in central and north‐eastern Europe. Seasonal trends in δ2Hf, which described the species’ migratory phenology through the Italian Alps, were correlated with feather δ13C, δ15N and δ34S values, indicating strong spatial discrimination related to continental patterns for these isotopes. We demonstrate how this combined information can define catchment areas and migratory connectivity of birds intercepted in the Alps. We highlight the importance of ringing data in defining directional priors to define Bayesian‐based probability surfaces using continental δ2Hf isoscapes, and how such information can be used to inform estimates of migratory connectivity.

“…Finally, it has been shown that resident and migrant raptors may segregate spatially in sympatry (e.g. Cardador et al, 2015), so another promising line of research is partial migration (populations composed of a mixture of resident and migratory individuals). Partial migration is ubiquitous in animals but has been scarcely explored in spite of its potential to further our understanding of the evolution of migratory behaviours, its ecological consequences, and its applied implications in a context of global change (Chapman et al, 2001).…”

“…Generally, stable hydrogen isotope values increase towards southern and southwestern directions (Hobson, Bowen, Wassenaar, Ferrand, & Lormee, 2004;Rozanski et al, 1993;West, Sobek, & Ehleringer, 2008) and stable hydrogen ratios in feathers (δ 2 H f ) can be used to assign origins of European migratory birds (Hobson et al, 2009). Therefore, a Pan-European breeding assignment using stable hydrogen isotope values is feasible (Bearhop et al, 2005;Cardador et al, 2015;Hobson et al, 2009). Therefore, a Pan-European breeding assignment using stable hydrogen isotope values is feasible (Bearhop et al, 2005;Cardador et al, 2015;Hobson et al, 2009).…”

“…Recently, stable isotope analyses have become an important tool in studies of population connectivity and origin assignment of breeding and wintering areas (Cardador, Navarro, Forero, Hobson, & Mañosa, 2015;Hobson, Lormée, Van Wilgenburg, Wassenaar, & Boutin, 2009;Hobson & Wassenaar, 2019). The main advantage of this method is that a very small feather sample (0.3 mg) can be taken from hunted, dead or living birds.…”

European Turtle Doves (Streptopelia turtur) are long-distance migrants and have experienced a population decline of more than 78% since 1980. Their conservation depends on refined knowledge of breeding origins and population connectivity. Feathers collected at stopover sites, but molted at breeding grounds, provide an opportunity to assign birds to potential regions of origin using tissue stable hydrogen isotope values and relate those to a European feather hydrogen isoscape. Here, 101 feather samples from 13 different breeding countries were analyzed to calibrate the European hydrogen isoscape and 101 feather samples from Spanish, Italian, Maltese, Greek, and Bulgarian stopovers were assigned to potential regions of origin. The assigned range of origin for all 101 individuals grouped together agreed with known distribution patterns. Bulgarian samples were mostly assigned to Russian areas. Possible origins of Greek, Italian, Maltese, and Spanish samples ranged from central to southern Europe. Individual assignments highlighted four broad regions of origin, corresponding to a cool/humid to hot/dry temperature gradient. Proportions of birds assigned to these regions varied among birds sampled at different stopover sites. Therefore, our results provide important information about population connectivity and may be useful to evaluate possible influences of hunting on Turtle Dove populations.
