Little Tern Welfare: Rare Coastal Nesters Needing Protection

Little terns are the UK's rarest breeding tern, nesting on shingle beaches alongside tourists. Their welfare requires active wardening and public engagement.

Key Facts

Only around 1,700 pairs of little terns breed in the UK each year
Little terns nest on open shingle beaches, the same beaches used by summer visitors
Each pair raises just one or two chicks per season, making every breeding attempt critical
Natural nest failure rates are high - overwash, predation, and human disturbance all take a toll
Little terns have declined by around 50% since the 1970s
Wardened beaches show dramatically higher hatching success than unprotected sites

Welfare Considerations

Little tern welfare is a direct function of human behaviour on beaches during June and July. A pair disturbed from their nest on a hot day can lose chicks to overheating within minutes. Vehicles on beach access routes crush nests and eggs. Dogs that flush incubating adults expose eggs to sun or cold. Yet at wardened beaches where rope cordons and volunteer wardens guide visitors around colonies, hatching success can be two to three times higher. This is one of the clearest examples of direct human behaviour impacting bird welfare.

What You Can Do

Respect all rope cordons around little tern colonies on beaches
Support the Wildlife Trusts' little tern wardening programmes through volunteering or donation
Keep dogs on leads on beaches near little tern colony signs
Never drive vehicles on beaches during the nesting season
Spread awareness of little tern nesting to others visiting shingle beaches
