We recorded these calls at a place designated “area R” in the Sam Houston National Forest. There are several individual clips separated by a few seconds of silence each. Please be aware the sounds are faint, so you will need headphones or need to turn your volume up very high to hear them clearly. There are trains in the background, and you hear the animals respond and mimic the trains horns. There is an unknown “moan” heard twice, and then a series of investigator calls with responses at the end.
