Where do seabirds go to find food?
What's the ocean like there?
Where did this White Tern get this fish?
To answer these questions, I use a combination of scientific tools.
GPS tracking tags tell us where the birds travel.
Remotely sensed environmental variables like chlorophyll and sea surface temperature tell us what the ocean was like when the bird visited different areas.
Chemical signatures, like carbon and nitrogen stable isotopes, tell us about the birds' diets.
