[Taxacom] Song from a bird unknown to me

[Jan Bosselaers]

Dear taxacomers,

Unfortunately, my knowledge of birds is rather limited. This afternoon, I sat in my garden in Belgium and heard the following bird song repeatedly: http://www.dochterland.org/bird_song.html 
It intrigued me because of its peculiar rhythm.
Can anyone tell me which bird it was? Please note that the high E is actually a quarter tone lower, but my version of "Finale" does not allow for microtones.

Best regards,

Jan Bosselaers
