Find out how a terrific team of Little Tern guardians is helping the threatened species tern a corner.

Weighing just 40 – 60g, the Little Tern is the smallest species of tern, and the second-rarest breeding tern, in the UK. Despite their size, these miniature marvels travel from West Africa every spring to nest on UK shores – that’s quite an achievement when you weigh about the same as a tennis ball!
Sadly, upon arrival these plucky ground-nesting birds face threats that have caused their numbers to plummet by 39% since the 1980s. Read on to find out more about Little Terns, the brilliant people working to keep them safe and what you can do to help.
In 1986, the RSPB and partners launched the ‘Great Yarmouth Little Terns Project’, which aimed to reduce disturbance and predation of Little Terns during the beach-nesting season. 2026 marks 40 years of the project, and as part of our celebrations, we’ve renamed it the ‘Tern Around Project’.
The project has grown over its 40+ years, with action now targeted across four key beach sites: Eccles-on-Sea, Winterton-on-Sea, Kessingland and North Denes.
When you think of a bird’s nest, you probably picture it high up in a tree. However, Little Terns prefer to build their nests directly on sand and shingle beaches, relying on the excellent camouflage of their eggs and chicks to avoid detection.
This should be an effective tactic to keep them safe. But sadly, as more people head to the beach, the pebble-like camouflage of the eggs and young leaves them vulnerable to being trampled underfoot and harmed by inquisitive dogs.
Spooking incubating adults can also cause eggs and chicks to fail, as an adult Little Tern’s instinct is to flee when threatened. This leaves eggs and chicks more vulnerable to predators, cold temperatures and being smothered by sand.
Climate change is also having a significant impact on Little Terns. The coastal location of their nests leaves them at risk from rising sea levels and extreme flooding events which can wash nest sites away.
Meanwhile, warmer seas are changing the nutritional value and distribution of sandeels, the Little Tern’s preferred food, and rougher waters are making it harder for the birds to spot them. This makes it difficult for adult birds to provide enough food for their young.
Finally, human development and coastal erosion are reducing the availability of nesting sites. In fact, the UK has lost 46% of shingle habitats since 1945.

Collectively, these factors have greatly reduced the availability of safe, quiet nesting sites. With the Terns forced to nest in fewer, larger colonies, adults, chicks and eggs have become much more vulnerable to predation.
Nesting Little Terns were first recorded in Norfolk in 1945, with 27 pairs regularly using the Scroby Sands sand banks off Great Yarmouth. In 1954, a few pairs began to use North Denes beach and then Winterton during the 1960s, where numbers increased to over 70 pairs following the loss of Scroby Sands to storm erosion.
Winterton remained the main site for Little Terns until the early 1980s when the North Denes colony grew, peaking at 369 pairs in 2006. The birds have also bred in Suffolk since the 1980’s, with Kessingland beach and nearby Benacre Broad hosting important nesting sites.
However, UK numbers of Little Terns have plummeted by 39% over the last 40 years. In the Tern Around project area, the population fell by 28% between 2011 and 2023 to a five-year average of 271 pairs.

Thanks to the efforts of the terrific Tern Around team, Little Tern numbers are slowly starting to rise in Norfolk and Suffolk. In 2025, the five-year average reached 314 breeding pairs, with the largest colony at Eccles-on-Sea hosting a minimum of 270 pairs and fledging a minimum of 455 chicks. However, it’s not all smooth flying.
North Denes beach has only supported occasional breeding attempts since 2010, and only one east Norfolk site supported breeding pairs in 2025. This was largely due to disturbance. Finally, just two sites in Suffolk supported Little Terns in 2025, representing a 75% loss of nesting sites since 1991.
These figures show the challenges that Little Terns face when they return to breed and highlight why the work of the Tern Around project is so vital.
‘The sound of Little Terns heralds the start of summer for many of the team and local community. It’s been great to see the team grow over the past few years and help so many chicks to fly despite all the challenges the birds face.
Through the team’s amazing efforts, there is a glimmer of hope as the Little Tern and Ringed Plover numbers show early signs of recovery. The dynamic coast also now provides opportunities for birds to breed at multiple sites, including previous locations such as North Denes.
This is great for Little Terns but will make it challenging to protect all the birds where they nest. Support from local communities and our amazing volunteers will be critical to continue to build on the project’s successes.’

The tireless enthusiasm of the local community is critical to the success of the Tern Around Project. In 2025, over 80 brilliant volunteers donated over 3000 hours to the project. Together, they helped to monitor the birds and engage with the public, raising awareness and answering any questions that visitors had.
‘I have been a volunteer with the Little Tern off-reserve project in northeast Norfolk for the RSPB for the last 3 seasons. It has been very rewarding, both physically and mentally. To know we are helping our second-rarest seabird to survive and increase in numbers gives me and many others great satisfaction.’

For our canine companions, Little Tern colonies can prove to be an irresistible point of interest. If you’re visiting one of our beaches during the nesting season (March – August), please follow the guidance and keep your dog on a short lead.
Nesting Little Terns are sensitive to disturbance. They are also a Schedule 1 species, which means it is illegal to disturb them. Whether you’re walking your dog, watching the birds or there to sunbathe, always give fenced areas a wide berth.
Vital RSPB projects like the Tern Around Project rely on the support of our marvellous members and generous donors. If you’d like to help keep the Tern Around Project in the air, please consider donating today.

Little Terns are listed on Annex I of the Birds Directive and as Schedule 1 of the Wildlife and Countryside Act (1981). This means they have the highest level of protection and makes it illegal to disturb nesting adults, their eggs or their chicks.
Due to their vulnerable status, the species is also an RSPB priority species, and the charity is working with multiple partners on multiple fronts to help reverse its decline.
The Tern Around Project is a collaboration between the RSPB, local communities and volunteers and conservation experts. Funding comes from Natural England, Great Yarmouth Borough Council, the Norfolk Green Infrastructure and Recreational impact Avoidance and Mitigation Strategy (GIRAMS) and Suffolk’s Wildlife Wise project.
