favorite forest, nature, or water sounds for white noise

We have lots of different favorite song threads, (like this one), but this is a thread for nature sounds.

Sounds of the forest, leaves rustling, rain falling, of water babbling or rushing by, waves crashing, or crickets chirping. That kind of thing.

When you are stuck indoors, at the computer, or trying to sleep, do you have a favorite source for using nature sounds as "white noise" to help tune things out?

A friend just shared this site:

And I think it's pretty awesome!

There are SO many different tracks to listen to that I learned that too much insect buzzing is the opposite of relaxing to me, as are water sounds that are too overwhelming, or some of these seemed to have irritating (to me) traffic sounds in the background, too. And noisy primates or odd birds didn't calm me either. Ha!

But if I found a track that sounded soothing, I could play it (I assume it loops?) while I worked and I do think it helped me concentrate. Who knew?

Do you have a favorite nature sounds source?

TREEFROGS!!!  Let me really know when spring is approaching, all that croaking...and then it just stops. And then one starts maybe 2 or 3 and then on with the chorus  

I love the sound of wind in the trees.  Ours are mostly juniper cedar so the noise is not a rustling of leaves.

I am not sure I can make that into white noise for indoors so my head is full of music.

Birdsong, distant waterfalls, babbling brooks.

I tried recording some in the past with no luck, I think you need a particular kind of mic or equipment.

Recently I started using an android app called White Noise Lite. It's decent for free.
