What is the primary threat concentrated along the migration corridor for the Hudsonian Whimbrel?
Answer
Habitat loss at crucial stopover sites
While various factors contribute to modern pressures on whimbrel populations, the specific decline observed in the Hudsonian Whimbrel is heavily linked to interruptions in its long-distance journey. The primary threat is concentrated along the migration corridor itself, rather than solely at the breeding or wintering grounds. This threat manifests as habitat loss at crucial stopover sites—the staging areas where they gather to fuel up. The interruption of this necessary process of rapid weight gain during these critical fueling windows directly impacts their ability to complete the journey successfully, which is essential given the immense distances they must cover.
