Rural ambient noise samples

[SampleSmith]

I need to find some good clean samples of waterfalls, babbling brooks, birds etc. These will be the only sounds in the project so really good quality is important and it will be about 30 min in length, so I'll need quite a few sounds.

Royalty free would be nice, but there should be enough money in this to pay fairly if required.

Can anybody point me in the right direction?


thanks,
Keith
