“Shorebird populations have shrunk, on average, by an estimated 70% across North America since 1973, and the species that breed in the Arctic are among the hardest hit.
Although the trend is clear, the underlying causes are not. That’s because shorebirds travel thousands of kilometres a year, and encounter so many threats along the way that it is hard to decipher which are the most damaging. Evidence suggests that rapidly changing climate conditions in the Arctic are taking a toll, but that is just one of many offenders. Other culprits include coastal development, hunting in the Caribbean and agricultural shifts in North America. The challenge is to identify the most serious problems and then develop plans to help shorebirds to bounce back.”
