Glamorgan Bird Club 
As [nearly] all the paper’s comments say, it’s probably a lone wild bird. Singletons are seen occasionally in S Wales. There has been on on occasions here near Penarth. There are 1000’s of them in SE England, incl central London. Some hers ago there used to be a roost of about 3000 in trees near Esher Rugby Club!
yea i know theres always one that posts such things on evening post x
The Singleton Park individual (a male) has been there at least three years. In fact, I filmed it a few days ago. It often flies around with the Jackdaw flock as they go to roost at dusk. If you listen to this video, you can hear the parakeet calling off-camera towards the end: https://www.youtube.com/watch?v=8R6JloZG2Fs
