“…Our data also suggest that the birds need to obtain resources for migration and other annual cycle stages (e.g., molt) in these countries. A similar migration pattern of the little ringed plover has been reported in the local population of Sweden 28 and in other small shorebirds in the EAAF, such as sanderling 34 and ruddy turnstone 8 . However, the migration routes and wintering areas of the six plovers we studied had less variability compared with the Swedish population, which showed a variety of migration routes among seven studied plovers.…”

“…Among the three subspecies of the plover (C. d. curonicus, C. d. dubius, and C. d. jerdoni) 23 , C. d. curonicus breeds across a wide range of the Palearctic including Europe and Japan; southern overwintering areas include sub-Saharan Africa, parts of the Arabian Peninsula, eastern China, and Indonesia 23,25 , as well as Southeast Asia 26,27 . The migration ecology and route of the European C. d. curonicus population has been clarified by bird banding 22 and by tracking using geolocators 28 . However, little is known about these aspects of the Asian population that move within the EAAF, although some information suggests the potential importance of several regions in the non-breeding season (Thailand, the Philippines, Taiwan, and Myanmar) and during migration (Thailand, Russia, and eastern China) 26 .…”

To maintain and recover populations of migratory waders, we must identify the important stopover sites and habitat use along migration routes. However, we have little such information for waders that depend on inland freshwater areas compared with those that depend on coastal areas. Recent technological developments in tracking devices now allow us to define habitat use at a fine scale. In this study, we used GPS loggers to track both spring and autumn migration along the East Asian-Australasian flyway of the little ringed plover (Charadrius dubius) as birds moved to and from their breeding grounds, gravel riverbeds in Japan. The birds we tracked overwintered in the Philippines and made stopovers mainly in Taiwan and the Philippines. The most important habitat during the nonbreeding season was rice paddy fields. Our findings imply that changes in agriculture management policy in the countries along the migration route could critically affect the migration of waders that depend on rice paddy fields. To maintain populations of migrant inland waders that move within the East Asian-Australasian flyway, it is necessary not only to sustain the breeding habitat but also wetlands including the rice paddy fields as foraging habitat for the non-breeding season. Migrant waders have been decreasing on a worldwide scale 1-5 due to various complex reasons 6 , such as land-use change 2 and increasing human activity 4,5. Since these migrant birds use multiple habitats and climatic zones within their annual life cycle 7 , identifying the migration pattern and route, including the habitats used along the way, is imperative for understanding the factors that affect population changes and/or contribute to efficient conservation activities. The loss or degradation of stopover sites is a particularly serious issue 1,2,4-6. In recent decades, therefore, many studies have investigated the migration patterns, detailed migration routes, and important stopover sites for several waders by using tracking methods ranging from traditional color flagging to advanced systems such as satellite and light-level geolocators 8-12. Studies of migration ecology of waders, however, have mainly focused on species that depend on coastal areas (i.e., shorebirds), and there is still little information on those that depend on inland freshwater areas. The low visibility of inland waders compared with that of coastal waders and the coarse spatial resolution of previously used tracking devices (light-level geolocators 13 , 50-200 km; Argos system, <150 m under good conditions and >1000 m under worse conditions 14) made it difficult to determine the fine-scale habitat use of individuals. However, inland natural wetlands have been dramatically declining on a global scale 15 , and some studies in the East Asian-Australasian flyway (EAAF) reported that waders that depend on inland habitat such as rice paddy fields have been decreasing 2,16. For migrant birds, rice paddy fields function much like semi-natural wetlands 17 , and rice is grown across a wide range of la...

“…However, the position of the migratory divide among Western Palearctic red-necked phalaropes is not shared with other species. The south-eastward migration of Scandinavian and Russian populations of phalaropes is shared with a small number of species, such as broad-billed sandpiper Calidris falcinellus, little ringed plover Charadrius dubius and redspotted bluethroat Luscinia svecica svecica (Verkuil et al, 2006;Hedenström et al, 2013;Lislevand et al, 2015), but the westward migration of populations from the north-eastern North Atlantic to the Pacific is unique. The migration route to the Pacific is highly suggestive of a biogeographic legacy, wherein the Nearctic breeding population expanded eastwards while retaining the migration route to the Pacific wintering area.…”

A Migratory Divide Among Red-Necked Phalaropes in the Western Palearctic Reveals Contrasting Migration and Wintering Movement Strategies

Non-breeding movement strategies of migratory birds may be expected to be flexibly adjusted to the distribution and quality of habitat, but few studies compare movement strategies among populations using distinct migration routes and wintering areas. In our study, individual movement strategies of red-necked phalaropes (Phalaropus lobatus), a long-distance migratory wader which uses saline waters in the non-breeding period, were studied using light-level geolocators. Results revealed a migratory divide between two populations with distinct migration routes and wintering areas: one breeding in the north-eastern North Atlantic and migrating ca. 10,000 km oversea to the tropical eastern Pacific Ocean, and the other breeding in Fennoscandia and Russia migrating ca. 6,000 km-largely over land-to the Arabian Sea (Indian Ocean). In line with our expectations, the transoceanic migration between the North Atlantic and the Pacific was associated with proportionately longer wings, a more even spread of stopovers in autumn and a higher migration speed in spring compared to the migration between Fennoscandian-Russian breeding grounds and the Arabian Sea. In the wintering period, van Bemmelen et al. Contrasting Movement Strategies in Phalaropesbirds wintering in the Pacific were stationary in roughly a single area, whereas individuals wintering in the Arabian Sea moved extensively between different areas, reflecting differences in spatio-temporal variation in primary productivity between the two wintering areas. Our study is unique in showing how habitat distribution shapes movement strategies over the entire non-breeding period within a species.

“…Its westward migration direction contrasts with the assumed migration pattern of the Scandinavian population, for which a small number of ring recoveries in autumn indicates a south‐eastern migration direction (Höhn , Schiemann , Alerstam , Bakken et al , Fransson et al ), strongly suggesting that these birds winter in the Arabian Sea. A south‐eastern migration direction is rather unusual among European breeding birds (but see Chamberlain et al , Verkuil et al , Hedenström et al ) and the idea that Scandinavian red‐necked phalaropes winter in the Arabian Sea (Höhn , Alerstam , Bakken et al , Fransson et al ) has never been confirmed. Even less is known about the behaviour of phalaropes during winter, when they are difficult to study due to their pelagic lifestyle.…”

We studied migration and wintering patterns of a wader with a pelagic lifestyle during the non‐breeding period, the red‐necked phalarope Phalaropus lobatus. Using light‐level geolocation, we obtained three full annual tracks and one autumn migration track of male red‐necked phalaropes caught during breeding in Scandinavia. These tracks confirmed expectations that individuals from the Scandinavian population winter in the Arabian Sea. Migration was accomplished in two to four migration leaps, staging for a few days in the Gulf of Finland (autumn) or the southern Baltic Sea (spring) and for up to a month in or near the Black and Caspian Sea (autumn and spring). In addition, travel speeds suggested that only the flights between the Baltic and Black/Caspian Sea are non‐stop, and thus the birds seem to make additional short stops during the other flights. Stopover time in the Black/Caspian Sea is only 8–10 d in spring but up to 36 d in autumn, which is longer than expected if only used for pre‐migratory fattening to cover the ca 2000 km to the Gulf of Oman. After entering the Arabian Sea via the Gulf of Oman, birds dispersed over the entire presumed winter range. Winter movements appear to correspond to the spatio‐temporal patterns in primary production linked to seasonally changing monsoon winds. These are not only the first tracks of Scandinavian red‐necked phalaropes, but also the first seabird tracks in the Arabian Sea, one of the most productive and dynamic marine areas on the planet.
