In a typical spring, breeding seabirds — and human seabird-watchers — flock to Stora Karlsö, an island off the coast of Sweden.
But in 2020, the COVID-19 pandemic canceled the tourist season, reducing human presence on the island by more than 90%. With people out of the picture, white-tailed eagles moved in, becoming much more abundant than usual, researchers found.
That might seem like a tidy parable about how nature recovers when people disappear from the landscape — if not for the fact that ecosystems are complex. The newly numerous eagles repeatedly soared past the cliffs where a protected population of common murres laid its eggs, flushing the smaller birds from their ledges.
