Hot Spots.

COOK'S PETREL Migration routes matter: Two nearby breeding populations of this species spend the nonbreeding season in different ocean regions. To calculate a "plastic exposure score" for each species, they first overlaid all the petrel routes with existing data on ocean plastic concentrations. SPECTACLED PETREL Ranked among the 10 birds in the study most exposed to plastic, this petrel is especially vulnerable: It breeds in only a single location, called Inaccessible Island, within a plastic exposure hotspot in the south Atlantic Ocean.
