Here is a wonderful site which provides sound clips of forests all over the world. I don’t see any from the Southeast but there are clips from Denali to the Western Sahara to New Zealand that you can sample to hear birds, beavers and bees as well as wind and waterfalls. You can try some out at https://timberfestival.org.uk/soundsoftheforest-soundmap/.
