What is the southern extent of the Hudsonian Whimbrel's wintering range during its massive migration?
Answer
The southern tip of South America
The migratory journey undertaken by the Hudsonian Whimbrel is exceptionally vast, demonstrating high physiological demands. After concluding their nesting season in the Arctic, these birds undertake a southbound push that takes them far south. Their wintering areas are extensive, stretching from staging grounds in the southern United States all the way down to the very southern tip of South America. This demanding round-trip requires precise timing, particularly as juveniles depart shortly after fledging, and adults follow later in mid-to-late August, relying on crucial coastal staging areas to fuel up for the sustained effort required to reach such distant southern locales.
