My wife says I talk too much; not all the time - mostly she'd like me to get off the computer and talk more! But out in the bush stalking our photographic prey, she thinks I am too noisy. My attitude is that most of the wildlife we are interested in is too disdainful of our hunting abilities to care if we are there or not. In fact, i think that many birds and animals become shyer if we appear to be trying to sneak up on them. On the other hand, make a bit of noise, carry on your conversation in a natural way and they will go on about their normal lives.
Sure, there are exceptions, but as you will see from the photos in my galleries, this approach seems to bear fruit for me, and I suspect for other photographers, too. If you are one, let me know; I don't plan to get a lot quieter, but maybe you will help me encourage my wife to shoosh up!
