- Abstract
To better understand how environmental changes affect existing migration networks and to guide targeted conservation measures, it is important to evaluate a migration network's connectivity and resilience and to identify crucial sites that might trigger network collapse. Swan geese, greater white-fronted geese, whooper swans, and bar-headed geese exhibited northward migration networks comprising 23, 72, 15, and 81 sites and southward migration networks comprising 45, 27, 13, and 67 sites, respectively. A well-connected migration network of well-protected sites can decrease migration costs and risks and thus facilitate bird migratory movements and increase migration success (Merken et al. [23]). As shown in Fig., compared with their southward migration network, the northward migration network of swan geese is even more vulnerable to collapse because the loss of only 14 sites will lead to network collapse.
