The effect of height is variable. There is, for instance quite a
difference between knee height and head height. It also varies
depending on the complexity of the site. It's not just the earth
itself, but all else, including bushes and trees, rocks and so on. In
general as you go up you simplify the sounds you pick up, less strong
local reflections and so on. So, the clarity of the recording
improves. Like all things you have to try it an see what you get. I'm
finding improvement clear to the height I use, would not mind trying
higher.

Note also that with a directional mic that you can place it higher
than your subject and pointing down towards it, thus cutting down more
distant unwanted sound. Not as useful with birds as with frogs.
