Population estimates have dramatically changed since 2000, with species both gaining and losing numbers. “I just don’t think there’s enough known about how these poisons are spreading through the ecosystem,” she said. The fate of the seagulls that routinely fly between the Farallones and San Francisco was also of great concern to opponents of the FWS plan, who feared the birds could ingest brodifacoum at the islands before returning to the city, where they often flock to tourist attractions in search of a snack. “Sometimes you’ll see the ground moving as mice are burrowing their little tunnels underneath,” said Pete Warzybok, a senior marine ecologist who leads conservation research in the Farallones.
