Oh, Olga, thank you :wave :
But I think, I asked a bit unclear for it :blush : and you´ve got me wrong . I would like to know, if I can buy this music, maybe on a CD, what is the name?

It's ok, my English is not very 'perfect'!!
I didn't find from youtube with the same name I found it youtube's 'free video editor, choose music' tool ( and chose that Mayfly' to play with the squirrel video, bacause I liked it..) There, in youtube editor, the name of the piece was:
Terry Devine-King, Mayfly, Mark Anderson, Alicia Anderson, Nikolaj Bjerr, electronic. 
This piece by name 'Mayfly' may be a pretty small part of a bigger composition!
I tried to find more about Terry Devine-King in youtube. There seems to be a lot of works by him. He is a composer, but he has also made some soundtracks to video games (??.. about them I do not know anything

), if I understood right.
Here is an interview with T D-K. Maybe you could ask there, or in some other youtube discussion thread on music by T. D-K!
http://www.youtube.com/watch?v=bNwgLpKvWdASomeone there tells that he has found something from T. D-K:
...Terry is a great find. I suggest you look through his library at Audionetwork I just licenced two of his peices for a disaster project... perfect! Terry is a great find. I suggest you look through his library at Audionetwork I..

I had never before heard anything about T D-K!! It was just by change!
I wish I could be for help more exactly..
