To which continents/regions does the Eurasian Whimbrel migrate to winter, depending on the subspecies?

Answer

Africa, Southern Asia, and Australasia

The migratory destinations for the Eurasian Whimbrel exhibit significant variation depending on which specific subspecies is being observed. Unlike the Hudsonian species which targets the Americas, the Eurasian populations travel much further afield across the Eastern Hemisphere. Their wintering grounds are distributed across a wide geographical spread, encompassing destinations such as Africa, Southern Asia, and even Australasia. The ability to cover these immense distances—potentially thousands of miles—places a strong evolutionary premium on traits related to efficient fat storage and flight stamina, as survival hinges on navigating these long-haul routes.
