New Guidance Launched to Help Protect Sheffield’s Swifts 

New information aimed at protecting Sheffield’s iconic swifts has been launched through a partnership between South Yorkshire Police, Sheffield Swift Network and the National Wildlife Crime Unit.

The guide, produced for residents, builders and local communities, explains what to do if a swift nest becomes blocked – one of the growing threats facing this much-loved species.

Swifts are a familiar sight over Sheffield each summer, arriving in May before returning to central Africa by late August. They spend almost their entire lives in the air and only land to nest in small gaps in buildings, often under eaves.

Blocked Nests

Their nesting habits also make them vulnerable. Swifts are highly site-faithful and will keep returning to the same nesting spot. If access is blocked by scaffolding, building work or repairs, they may continue trying to enter, risking injury or even death.

The leaflet highlights the urgency of protecting nesting sites at a time when swift numbers are in steep decline. The species is now Red Listed as a Bird of Conservation Concern, with numbers falling by around 70% between 1995 and 2024.

Clear Advice for the Public

The guidance sets out practical steps for anyone who discovers a blocked swift nest. It advises people to speak to those responsible for the work, share the leaflet and explain the legal protections in place.

If concerns are not resolved, residents are advised to report the situation to police via 101 and request a Wildlife Crime Officer.

Importantly, the leaflet reminds the public that all wild birds, their nests and eggs are protected under the Wildlife and Countryside Act 1981, making it an offence to damage or destroy an active nest. 

Partnership Working to Tackle Wildlife Crime

This initiative shows the value of collaboration between conservation groups and law enforcement. South Yorkshire Police, Sheffield Swift Network and the National Wildlife Crime Unit aim to raise awareness, prevent offences and protect nests during the breeding season.

‘I am impressed how responsive the police have been in supporting this work to ensure that the public are aware of their responsibilities when it comes to breeding swifts – being clear about the facts means that it is easier to advise people.’ Flora Blackwater – Sheffield Swift Network.

Protecting Sheffield’s Summer Visitors

With nest loss a major cause of decline, protecting access to nesting sites is vital. The leaflet helps local people act quickly – because for swifts raising chicks, every moment counts.

Residents are encouraged to look out for nesting activity and act promptly if they suspect a problem.

Sheffield Swift Network will also continue supporting residents who report concerns.
