How long might the intensely pelagic Sabine's Gull spend staging offshore during Atlantic migrations, specifically mentioning the Bay of Biscay?

Answer

Up to 45 days

Following the conclusion of the breeding season, the Sabine's Gull shifts dramatically to a pelagic existence. During its migration along the Atlantic route, the species engages in staging behavior in specific offshore areas. The text notes that the birds may spend a significant period, quantified as up to 45 days, staging offshore in locations such as the Bay of Biscay before continuing their journey onward to cold-water upwelling zones off the coasts of South America or Africa.
