An unusual site in the sky above Belfast has been attracting on-lookers this week.
A murmuration (aka a collective flock) of starlings fill the sky at twilight and will continue to do so every evening this winter.
The thousands of birds seek shelter for the night under the Albert Bridge, but not before their beautiful night time 'stroll.'
'A lot of it is safety in numbers from their predators,' says Orla Maguire of the Belfast City Council. 'But also I think there must be some social element to it.'
Unlike crows, which can be aggressive, these birds are a gentler kind. Many came from Eastern Europe where temperatures are colder.
'They're very loud when they come under the bridge,' Ms Maguire added.
