I have never seen this technique of removing mouth noises (clicks and random sounds) mentioned about anywhere. Thus, I have decided to reveal it to you so it can help you make better wildlife videos! (Or any other video for that matter.)

Larger summary: When you're talking into a microphone, your mouth can make noises that sound like clicks in the audio. Although there are some automated ways to remove these, the easiest and most effective way is to manually use the repair tool in the opensource software Audacity. I'll go over several examples in real time with some of my own audio. After watching this guide, you'll be able to easily remove mouth noises too!
