Grey Plovers take flight on annual migration
Two Grey Plover shorebirds that spent their summer fattening up north-west of Adelaide have recently been tracked in China on their way to their northern breeding grounds in the Arctic.
The extensive mudflats and mangroves at Thompson Beach in Adelaide’s International Bird Sanctuary provide plovers and other shorebirds with a feasting smorgasbord over the summer, but when the instinct to migrate kicked in during March, as it does every year, these plovers took to the sky with the favourable south-easterly winds.
Tracking their journey
The plovers were fitted with tiny solar-powered satellite trackers to help researchers better understand the migration of shorebirds who spend their summers in Adelaide.
They left Thompson Beach to fly along the East Asian-Australasian Flyway to China, with one plover making its first landfall near the Aogu wetland in Taiwan.
After a few weeks of recuperating, this plover headed north, landing on the Chinese mainland in April and currently resides north of Shanghai.
The other plover flew directly to the Chinese coast, landing in early April and cruising around the mainland. She currently resides north of Bohai Bay in the northeast China.
They are now feeding and resting up for the next leg of their journey. As the snows thaw in the Arctic these and hundreds of thousands of other birds from the East-Asian Australasian Flyway and other global flyways will converge there in June to breed.

Migration mysteries
The exact movements of the Grey Plover as with many migratory shorebirds is not well understood.
Researchers are trying to unravel the mysterious details of the birds’ annual migration route.
