From Rare Bird Alert
A new report published this month has highlighted the threat marine plastic pollution poses to seabirds in the north-eastern Atlantic region. Researchers found that, of 34 seabird species investigated, 74% had ingested plastic.
The authors of the new study, from the North Highland College UHI’s Environmental Research Institute, part of the University of the Highland and Islands, and the RSPB Centre for Conservation Science collated data from all known studies reporting instances of plastic ingestion and nest incorporation in seabirds around northern Europe, Scandinavia, Russia, Greenland, Svalbard, the Faroes and Iceland.
Dr Nina O’Hanlon, of Environmental Research Institute, explains: “Marine plastic pollution is an increasing and global environmental issue which poses a major threat to marine biodiversity. The production of plastic continues to rise with millions of tons entering the oceans each year. Seabirds can ingest plastic, become entangled in it or incorporate it into their nests, causing impacts which may have negative consequences on reproduction and survival.”
Dr Alex Bond, RSPB senior conservation scientist, said: “The north-eastern Atlantic Ocean is home to internationally important breeding populations of seabirds and an amazing array of other marine life. Solutions to plastic pollution in the oceans require concerted action at its source on land – 80% of marine litter is thought to come from land – especially by producers and users.
“The properties which make plastics desirable are the very things which make it problematic,” Dr Bond continues. “Due to its low cost, approximately half of all plastic items are produced for single-use. Plastic never breaks down, it only breaks up, into smaller fragments which remain in the environment and, as its density varies, it can be found throughout the water column, increasing the number of species which come into contact with it.”
While the team’s research highlights some concerning statistics, its report concludes that more coordinated, comprehensive and detailed investigations are required on plastic ingestion and nest incorporation to assess the full impact marine plastic is having on seabird populations.
Dr O’Hanlon explains: “In the north-eastern Atlantic Ocean, an area of international importance for seabirds, there has been little effort to better understand how marine plastic affects different seabird species over time and regionally. We actually know very little about the current prevalence of plastic ingestion and nest incorporation for many species, several, like the long-tailed duck and Atlantic puffin, which are globally threatened. Only 49% of the 69 species which are commonly found in the region have been investigated for plastic ingestion. We believe it’s vital to have a multi-jurisdictional, coordinated and collaborative effort to gain a more comprehensive and current understanding of this important issue.”
The group’s research was undertaken as part of Circular Ocean, a project funded by the EU’s Northern Periphery and Arctic Programme, which aims to incentivise the reuse and recycling of marine plastic litter in remote and rural regions.

Tell the Prime Minister and demand a reply.
This is really bad news. Surely humans are capable of finding an environmental alternative to plastic. I guess if we vote with our feet and do not buy single use plastic bottles eventually the manufacturers will get the message.
We need to get shops to go back to paper bags for produce, and put a pollution tax on plastics
Absolutely! Another thing we can do is promote just how bad balloons are for marine life https://www.thespruce.com/how-balloons-hurt-birds-386297
