The good thing with good cameras is that it gives so much room for cropping and it's still possible to get good results.

Animals are afraid of people, luckily. Sometimes you can see that those animals which live close to humans are less afraid, but it's not always good for them.

The "Sit like a stone" could work, at least in some occasions. In summer I was taking photos in another place and there I was sitting still next to a large stone. Next time I should attempt to look like a stone again :)
