“…The parents of this young bird were a female Red Kite and a male Black Kite confirmed by direct observations and documented by photographs. The bird was tagged with an OT-E25B-3 G logger (20 g, Ornitela, Lituania) fitted on to the back of the bird and secured with a harness consisting of 6 mm Teflon ribbon encircling the body by two loops around the base of the wings joining in front of the breast bone; following the same method as Literák et al (2019aLiterák et al ( , 2019b. The logger functioned in Global Positioning System/Global System for Mobile Communication (GPS/GSM) systems.…”

The winter months are an important part of the year for raptors as survival throughout this period is critical for the succeeding year's population recruitment. We reveal novel insights into the wintering of kites (Milvus spp.) on the Mediterranean island of Crete, Greece. We use a combination of 1) direct field observations, 2) online photograph searches and 3) analysis of satellite telemetry data from a tagged hybrid Red Kite × Black Kite (Milvus milvus × M. migrans migrans). The number of observations of wintering kites has increased since 1998. The wintering of numerous Black Kites with morphological features of both subspecies (M. migrans migrans and M. migrans lineatus) and a hybrid Red Kite × Black Kite is a new phenomenon on Crete.

“…In the autumn northern European populations undergo short-distance migration and winter in southern Europe including France, Italy and the Iberian Peninsula. Southern European populations tend to be resident all year round (Cramp & Simmons 1980;Génsbøl & Thiede 2008;BirdLife International 2015;Literák et al 2018Literák et al , 2019a.…”

“…From 2013 to 2020, 44 red kites were captured during their wintering seasons in Spain, in different provinces: Álava (18), Huesca (15), Segovia (10) and Toledo (1). There were 24 adults and 20 immatures (at the time of tagging); in terms of sex, 9 were males (adults), 4 females (adults) and 31 were individuals whose sex was not determined (11 adults and 20 immatures; Table S1).…”

“…However, there are still several gaps in the knowledge of the spatial ecology of many raptors, such as the red kite (Milvus milvus). The ecology of the red kite during its wintering period has been mainly studied based on field observations [10][11][12][13][14] and just a few studies have used GPS tracking technology [15,16] The red kite (Milvus milvus, Accipitridae) is a medium-sized, partially migratory raptor from the Western Palearctic. It is a facultative colonial bird that tends to group in roosts during winter, with an average of 70 individuals per roost [17].…”

To develop effective conservation strategies for migratory birds, it is essential to understand the ecology of a species at each biological phase, including its wintering (or non-breeding) season. For the red kite (Milvus milvus), an endangered raptor from the Western Palearctic, its wintering ecology is little known. We tagged 44 red kites using GPS/satellite transmitters to study their non-breeding seasons in Spain. Two spatial strategies were recorded: 34 individuals (77%) spent all their wintering periods in only one area, whilst the remaining individuals (23%) moved between two main areas at least once. This strategy, however, was not consistent over the years. In the latter case, the distance between wintering areas was 311.6 ± 134.7 km, and individuals usually spent equally long periods in each area (96 ± 35 days). No effects of age or sex were found on these area shifts, so they may have been driven by food or habitat resource availability. We also found high interindividual variability in home range sizes. The home ranges of adults were two- to three-times smaller than those of immatures, probably due to a better knowledge of the territory.

“…We tagged all birds with 20-g Saker H loggers (Ecotone, Gdynia, Poland) weighing on average 2% of the kites' body mass. We fitted loggers onto the back of the birds and secured them with a 6-mm Teflon ribbon harness encircling the body in 2 loops around the base of the wings and joining in front of the breastbone following similar methodology to Literák et al (2019aLiterák et al ( , 2019bLiterák et al ( , 2019c. The loggers operated in GPS-GSM systems and received signals every 3 hours depending on signal strength.…”

Understanding intrinsic and extrinsic influences of movement behavior in migratory species, with the potential to recommend management actions for species of conservation concern, requires data from across the species' range. For some raptor species, such as the red kite (Milvus milvus; kite), existing data focus on breeding populations or movements en route to wintering areas without considering movements within the wintering areas. Here, we contribute to filling this knowledge gap by investigating landscape-level associations of kites in their southwestern European winter ranges between 2015 and 2020. We also explore aspects of the migration process in terms of geographical patterns in the location of over-wintering grounds, including time spent and distances traveled within them. We predicted that space use in overwintering areas would be linked to the proportional amount of open, lowland, or urban land cover they contain at the landscape level. Specifically, we tested whether winter range sizes (95% kernel density estimator [KDE] home ranges and 50% KDE core areas) would be smaller in areas with greater proportional open and urban land cover within kite ranges. Controlling for the effects of age and sex, we compared results in 3 over-wintering regions: the Iberian Peninsula, Italy, and the Pyrenean region of southern France. We tracked 36 kites by global positioning system-global system for mobile communications (GPS-GSM) telemetry over 70 individual winters between 2015 and 2020. Kites wintering in the Pyrenees had
