“…Nevertheless, this does not exclude the possibility that birds can move within winter at smaller spatial scales, as documented, for example, amongst individually marked tufted ducks (Gourlay‐Larour et al ., ). In addition, several other waterbirds are known to show winter site fidelity to some extent (Guillemain et al ., ; Petersen et al ., ). This implies that some part of the population is responding to new feeding opportunities as these arise from changes in temperature, resulting in the observed shifts in range.…”

Climate change is predicted to cause changes in species distributions and several studies report margin range shifts in some species. However, the reported changes rarely concern a species' entire distribution and are not always linked to climate change. Here, we demonstrate strong north-eastwards shifts in the centres of gravity of the entire wintering range of three common waterbird species along the North-West Europe flyway during the past three decades. These shifts correlate with an increase of 3.8 °C in early winter temperature in the north-eastern part of the wintering areas, where bird abundance increased exponentially, corresponding with decreases in abundance at the south-western margin of the wintering ranges. This confirms the need to re-evaluate conservation site safeguard networks and associated biodiversity monitoring along the flyway, as new important wintering areas are established further north and east, and highlights the general urgency of conservation planning in a changing world. Range shifts in wintering waterbirds may also affect hunting pressure, which may alter bag sizes and lead to population-level consequences.

“…However, the latter may have a greater impact on survivorship, because mortality may be higher on wintering grounds than at breeding sites (Hestbeck et al 1991, Newton 1998. To understand the demography, breeding and wintering connectivity, genetic structure, and population regulation of a migratory bird species, it is necessary to know the level of philopatry (Robertson and Cooke 1999, Guillemain et al 2009, Petersen et al 2012. Breeding and wintering philopatry are basic life-history parameters that are important for modeling population growth and also have important conservation implications (Latta andFaaborg 2001, Petersen et al 2012).…”

“…Huge efforts have been devoted worldwide to monitor migratory birds using the ringing of tens of millions of individuals. These ringing schemes have greatly helped avian ecologists to understand timing and patterns of movements [9] – [11] , assess population turnover rates [12] – [14] , and estimate demographic parameters like survival and site fidelity [15] . Unfortunately, due to spatial heterogeneity in recovery probability ringing data are not well suited to quantify movement patterns.…”

Partial migration is a pervasive albeit poorly studied phenomenon by which some individuals of a population migrate while others are residents. It has tremendous consequences on seasonal variations of population size/structure and therefore management. Using a multi-event capture-mark-recapture/recovery (CMR) approach, we assessed seasonal site occupancy, survival and site fidelity of a partially migratory diving duck, the Common pochard (Aythya ferina), in an area potentially including both local breeders and winter visitors. The modelling exercise indeed discriminated two different categories of individuals. First, locally breeding females which had a probability of being present in our study area during winter of 0.41. Females of this category were found to be more faithful to their breeding site than males (breeding site fidelity probabilities of 1 and 0.11, respectively). The second category of birds were winter visitors, which included adults of both sexes, whose probability of being present in the study area during the breeding season was nil, and young of both sexes with a 0.11 probability of being present in the area during the breeding season. All wintering individuals, among which there was virtually no locally breeding male, displayed a high fidelity to our study area from one winter to the next (0.41–0.43). Estimated annual survival rates differed according to age (adults 0.69, young 0.56). For both age classes mortality was higher during late winter/early spring than during summer/early winter. Our study is among the first to show how and under which conditions the multi-event approach can be employed for investigating complex movement patterns encountered in partial migrants, providing a convenient tool for overcoming state uncertainty. It also shows why studying patterns of probability of individual presence/movements in partial migrants is a key towards understanding seasonal variations in numbers.
