A flock of 1,000 clay starlings on wooden poles has been "flown" across the Downs in Bristol.
The Bristol Murmuration was sculpted by people from Henleaze, Stoke Bishop and Westbury-on-Trym to highlight the dramatic decline of the species.
Zoe Cameron, the artist leading the project, said the "wonderful array" of birds included "very exotic-looking starlings" as well as green finches.
The murmuration will be on display on Durdham Downs until 25 October.
Once a common garden bird, starling numbers have fallen dramatically since the 1970s.
Despite the declining population, thousands of the birds can be spotted each winter flying together and creating mesmerising patterns called 'murmurations'.
"I'm delighted that so many people have been part of this stunning artwork," said Ms Cameron.
Part of Bristol 2015, each ceramic bird was individually moulded out of clay in free public workshops in the area.
Mounted on poles, the flock was "flown" across the Downs before congregating en masse on the corner of Parrys Lane and Westbury Road.
"All the birds are numbered and will be returned to their creators at the project's end, to rest and roost."
