Differentiating between stopover and staging sites: functions of the southern and northern Yellow Sea for long-distance migratory shorebirds
Evidence-based protection of migratory birds at flyway levels requires a solid understanding of their use of ‘stopping sites’ during migration. To characterize the site use of northward-migration great knots Calidris tenuirostris in China, we compared length of stay and fuel deposition during northw...
