Birdsong identity help

I hear the attached song every day, morning and night, this is just a short clip as the long clip was too large to upload, this 5 beat clip repeats regularly and hardly varies. With the occasional 6th beat, almost as an afterthought. Heard in a small copse with oak, ash and hazel as the main trees. Please help, it's driving me crazy, I can be stood directly beneath it but never see it.

  • It could be something like a Great Tit ...... they have a wide range of calls ....... but I'd like to hear more of it.
    Is there any way you can strip out the audio from the video file? Audio clips (say mp3) are usually much smaller than video mp4 files.
    Incidentally, it's not a good idea to use your email address as part of your username. This forum is visible to non-members and we've recently been plagued by spammers so you could get unwanted emails.
