Not used to seeing these well.
No interactions present.
I thought that bird looked familiar and I noticed you saw it at Pulborough Brooks! (I probably passed you on the way round)
I have only started going round there regularly at the end of last year but the people in the know tell me the nightingales are easy to see now when they have just arrived back but become less visible later on when they are nesting.
Thank you for posting the pictures - I do think nightingales are a lovely colour.
