I'm looking for a good sample library of nature sounds.  I haven't 
uncovered anything yet so I'm wondering if any of you are aware of some 
good ones.   I am specifically interested in natural atmospheric sounds 
such as water (streams, waves, rain, etc), wind (including rustling 
leaves, etc), thunder as well as atmospheric animal sounds like 
crickets, other insects, and things like that.  Other animal sounds 
that may be of interest are those with atmospheric or melodic 
characteristics.

Thanks!
Matthew
