The RSPB's appealing for volunteers in Norfolk, Suffolk and Essex to help one of the UK's rarest seabirds, the Little Tern.
Their numbers have seriously declined in recent years as they struggle to find safe beaches to nest and feed their young.
Over a third of the UK breeding population make a home in East Anglia.
“Norfolk beaches are fantastic places to see little terns. Over a third of the UK breeding population make a home in East Anglia, and some of the largest colonies in the UK can be found here in Norfolk. However, our beaches are busy places and the little terns rely on our help to ensure chicks thrive and are able to successfully follow their parents back to Africa in August."
– PHIL PEARSON, SENIOR CONSERVATION OFFICER
The RSPB says that the birds are often disturbed when nesting by people as well as being vulnerable to predators such as crows or foxes. Severe weather events have also affected numbers in recent years.
