... Second, satellite tracking is now a widely used method to track wildlife dispersers, particularly carnivores [17,66,70]. Our large investment in satellite tracking (170 individuals receiving 191 collars) made it possible to quantify many metrics in the studied population, thus moving away from earlier natural history reports often limited to describing extensive movements in this species [38,39,41]. ...

... In the case of those penguins and shags, we found that segregation was most probably generated by optimal foraging in relation to habitat differences on a local scale, including the distance to the coast and the bathymetric depth of the foraging areas [7]. A similar future study, using current biologging tools (e.g., [60][61][62]) in combination with further DNA-barcode-based diet analyses, would allow us to gain even more in-depth knowledge of the ecological segregation between the Falkland Flightless Steamer Duck and the Patagonian Crested Duck from New Island. ...

... Met hamstervriendelijke maatregelen in het kader van agrarisch natuurbeheer en met hamsterreservaten probeert men sinds 2002 een duurzame populatie op te bouwen in Zuid-Limburg; zo worden graan en luzerne geteeld, maar niet volledig geoogst. Het aantal hamsters nam in de eerste jaren spectaculair toe, om vervolgens weer te dalen (CLO, 1073;Müskens et al., 2018). Het is op dit moment noodzakelijk om elk jaar opnieuw een aantal dieren uit het fokprogramma uit te zetten. ...

... The greater white-fronted goose (Anser albifrons) is a long-lived, long-distance migratory herbivore with a circumpolar distribution [28]. Nesting in Arctic and subarctic habitats and wintering in temperate zones, the species exhibits complex patterns of migration [29][30][31][32][33], genetic and morphological differentiation [34,35], and variation in ecological (e.g., foraging) strategies (e.g., [36,37]). Greater white-fronted geese exhibit life history traits such as extended parent-offspring associations [38][39][40], strong long-term pair bonds (1.6% lifetime maximum divorce rate, [41]), solitary breeding [28], spring or summer pairing [5], and social learning of movement behavior ( [42]; see [43] for summary of migratory culture), all of which suggest the potential for genetic differentiation at both regional and finer spatial scales. ...

... (Lameris et al. 2017b). Tracking devices attached with backpack harnesses seem not to hamper barnacle geese in their breeding behaviour, with the exception of a slight delay in the timing of nest initiation (Lameris et al. 2018a). Tracking devices collected GPSpositions every 30 min (PTT satellite) or every 5-60 min (GPS-GSM loggers, depending on battery charge). ...

... However, in a field situation with HPAIv-infected wild avian species in the environment, the expected amount of virus and the concentration of virus produced by wild avian species-a combination of a low prevalence of infected wild avian species and a high degree of aerial dilution-is probably very low. Prevalence estimates of HPAIv-infected live aquatic avian species during the HPAI-epidemic season of 2014, 2014-2016 and 2016-2017 in the Netherlands were 5 per 10,000, 8.3 per 10,000 and 61 per 10,000 sampled live aquatic avian species, respectively [20][21][22]. The fact that pathogens may enter the poultry houses via air-inlets attached to particles carried by the wind was confirmed by our finding of the Campylobacter genome in some of the PM and dust cloth samples. ...

... To date, USUV epidemiological surveillance programs have focused primarily on the molecular (RT-qPCR) and serological detection (virus neutralization tests and enzyme-linked immunosorbent assays) of USUV-specific genome and antibodies, respectively. Passive and active surveillance efforts of wild birds and captive zoological birds are regularly performed, among others in Austria Chvala et al., 2007;Meister et al., 2008;Rubel et al., 2008), Belgium (Rouffaer et al., 2018;Benzarti et al., 2020), France (Vittecoq et al., 2013;Roesch et al., 2019;Constant et al., 2020), Germany (Ziegler et al., , 2022Michel et al., 2018Michel et al., , 2019, Hungary Weidinger et al., 2020), Italy (Manarolla et al., 2010;Savini et al., 2011;Tamba et al., 2011;Giglia et al., 2021;Lauriano et al., 2021;Scaramozzino et al., 2021;Zecchin et al., 2021;Mancuso et al., 2022), the Netherlands (Lim et al., 2018), Spain (Jurado-Tarifa et al., 2016;Marzal et al., 2022), and the United Kingdom (Buckley et al., 2003;Horton et al., 2013;Folly et al., 2020). Nonetheless, a genomic surveillance of USUV is rare, with a limited number of available full-genome sequences. ...

... Serum samples were tested for the presence of H5-specific and NP-specific antibodies. H5-specific antibodies were detected by using an HI test performed as described previously, using in-house turkey erythrocytes (34). Briefly, serum samples were treated overnight at 37°C with inhouse-generated Vibrio cholerae filtrate containing receptor-destroying enzyme and subsequently inactivated at 56°C for 1 h and adsorbed with 10% turkey erythrocytes for 1 h at 4°C. ...

... However, this should be dependent on actual animal behavior durations and device storage and transmission capabilities 18 . Accelerometers are more accurate at predicting behaviors with greater head movement (e.g., foraging) when placed on the neck than backpack-style devices 20,62 . Although we did not account for other factors that may influence behavioral state durations in geese, such as social hierarchy in flocks (e.g., family group with presence of goslings, paired or unpaired geese), or flock size, our goal was to quantify individual decision-making strategies made by geese relative to their behavior regardless of these factors to encompass strategies of all adult individuals of varying status and quality within the population. ...

... 3: Verschiedene bodenbrütende Vogelarten -hier eine Stockente (Anas platyrhynchos) in der Hetter -fallen regelmäßig modernen Kreisel-Mähwerken zum Opfer. : Lind 1961, Glutz von Blotzheim et al. 1986, Beintema et al. 1995 (Schekkerman & Müskens 2000). Es scheint also auch am Unteren Niederrhein der niedrige Aufwuchserfolg der Jungvögel eine Rolle beim Bestandsrückgang zu spielen. ...
