Foraging patterns and diet composition of breeding Pied avocets (Recurvirostra avosetta) in the German Wadden Sea

Differences in dietary specialization, habitat use and susceptibility to human disturbance influence feeding rates and resource partitioning between two migratory Numenius curlew species

“…Many migratory shorebirds depend on abundant food-rich stopover sites across coastal landscapes to fuel their migration (Horn et al, 2020;Martins et al, 2013;Piersma, 1987). Within these highly heterogeneous coastal environments, tidal mudflats and adjacent saltmarshes represent some of the most important foraging habitats due to the richness and abundance of macrozoobenthic prey resources (Burger et al, 1997;Enners et al, 2019;Jing et al, 2007;Li et al, 2014). Shorebird population viability depends on their ability to exploit these habitat-dependent food resources during climatically variable migration seasons (breeding vs. non-breeding).…”

Home Range and Habitat Disturbance Identification for a Vulnerable Shorebird Species (Larus saundersi) in the Yellow River Delta, China

“…Home range size and patterns of space utilization can be determined using analytical methods based on the GPS tracking data. In recent years, the GPS tracking technique has been applied to studies of different types of animals, such as Audouin's gull (Larus audouinii) (Christel et al, 2012), Pied avocets (Recurvirostra avosetta) (Enners et al, 2019), Mongolian gazelles (Procapra gutturosa) (Ito et al, 2018), giant noctule (Nyctalus lasiopterus) (Nad ˇo et al, 2019), and Australian Wood Ducks (Chenonetta jubata) (McEvoy, Hal, and McDonald, 2019) to explore the relationship between species and environment. Considering its importance in the field of animal ecology, Coxen et al (2017) indicated that satellite transmitters may be the only tool available to effectively track fine-scale movements of highly mobile, difficult-to-access species.…”
