# A Critically Endangered Balearic Shearwater eats krill

Maite Louzao ([Centro Oceanográfico de Gijón/Xixón](http://www.ieo-gijon.es/), Spain) and colleagues have published early-view in the journal [*Marine Ornithology*](http://www.marineornithology.org/) on krill regurgitated by a ACAP-listed and [Critically Endangered](http://www.birdlife.org/datazone/speciesfactsheet.php?id=30026) Balearic Shearwater *Puffinus mauretanicus* during the chick-rearing season.

 “In this study, we report observations that, during breeding season, the diet of the endemic Balearic Shearwater includes macrozooplankton, specifically the krill *Nyctiphanes couchii*.  Further research in needed to accurately assess the importance of euphausiids in the diet of the Balearic Shearwater.”
