More than 100 skylarks have been recorded in a conservation survey at Jersey airport.
Ports of Jersey firefighters take part in the airfield survey every year.
It is conducted on behalf of the Ornithological section of the Société Jersiaise and the Jersey Biodiversity Centre
Despite the skylark declining dramatically in across Britain, 110 were identified compared to just 36 recorded 18 years ago.
The airfield grassland is a favoured nesting site for the red list species, which the Airport Fire Service say is not a danger to aviation because of their small size.
Firefighter, Neil Harvey, said: “The airfield grassland has become a favoured site for nesting and roosting skylarks in recent years, and is now Jersey’s primary habitat for the birds.
"We are pleased to be involved with the ongoing surveying and conservation of the Skylark in Jersey.”
