Shags that eat together, stay together

Love makes the world go around and in Kerguelen Shags, so does food. These birds are endemic to the Kerguelen Islands in the Southern Indian Ocean, one of the most isolated places on Earth where they nest on cliff tops. Dr Eloide Camprasse was lucky enough to visit this isolated wilderness to study the foraging behavior and mate choice of these birds and what she found was fascinating. Her research revealed that these seabirds breed with monogamous mates that match their feeding habits even though they're not similar in morphology. Partners dived to more similar depths and in more similar places, compared to birds that were not paired and they had similar diets.
