	First read the answer from Dr Jos van den Broek which is the
scientific response to your question, after that, you have to think 
about the environement of rabbits, which is NOT always green grass, but
also forests (at least edge), they also have a big part of their 
alimentation composed of roots and tubers. Then, think a little bit more. 
It's not so easy to see a brown animal in (tall) grass, but it's really 
easy to see a green animal on a brown surface.
	The exemple of insects is only a problem of scale. Did you ever
try to put a rabbit on a single blade???
