TL;DR
A Grey Plover tracked from Singapore to Siberia reveals unexpected migration patterns, challenging assumptions about its breeding population and highlighting the impact of climate change.
Contribution
This study provides the first evidence of a Grey Plover from Southeast Asia migrating to Siberia, challenging existing population delineations and migration route assumptions.
Findings
A Grey Plover from Singapore migrated to Siberia, suggesting it belongs to a previously unlinked population.
The bird's post-breeding westward migration contradicted prevailing winds, possibly due to habitat changes from climate change.
The plover's migration route included unexpected detours, indicating potential shifts in breeding or staging grounds.
Abstract
Shorebird populations are declining across the world due to factors such as habitat loss and climate change. Identification of shorebird migration routes and important stopover sites can facilitate the implementation of strategic and effective conservation measures. Using a satellite transmitter, we successfully tracked the migration of one Grey Plover ( Pluvialis squatarola ) from its wintering grounds in Singapore north along the East Asian‐Australasian Flyway (EAAF) to its breeding grounds located east of the Taymyr Peninsula in north‐central Siberia. This provides the first evidence that the Singapore plover could be part of the Yamal/Taymyr population that is known to only migrate south via the East Atlantic Flyway and winter in Western Europe. After breeding, the bird took an unexpected westward migration towards northwestern Taymyr Peninsula where it stopped at two locations for…
