Large amounts of plastic are adrift in the sea. Most of it is microplastic, some of which often ends up in seabird stomachs. A group of researchers met in Tromsø recently to discuss how to best monitor the amounts of plastic in birds. According to their report from the workshop, samples of regurgitation and faeces will be of interest if such monitoring were to be implemented.
