I go for short hikes as part of my ordinary weekend routine. Many of our north Texas woodland hikes involve riparian woods--trees that mostly exist near water. The red-eared slider is a turtle often found amid the creeks, rivers and ponds by which I hike.
It has red markings on the side of its head, and it slides into the water quickly if alarmed.

My song "Red Eared Slider" came out on the latest Classwar Karaoke netlabel compilation, which is volume 17. The song has a bit of history, having been purposed for one netlabel, and then re-purposed for its initial release on Classwar Karaoke.
I made it with a simple software synthesizer and samples of a hand-held woodwind instrument.

Here's the song at the Free Music Archive:
