Been spending a lot of time on here!
ok. according to that data, if I am reading it right, you have a 38-380mm, full frame equivalent lens. So you'll need a 4/3 system lens that is about a 20-200mm zoom, or an APS-C zoom that is 24-240mm to meet that performance.
They do make these lenses, but my guess is that the shorter focal lengths aren't used much, and you'll be better off with a longer lens than a shorter one. Something like a 70-300mm lens is probably going to be more useful.
As I said before, 4/3 is a good option because of crop factor. Because the sensor is smaller, the amount of magnification you'll get will be more with less focal length, this is the reason why your point and shoot has a 6.3-63mm lens, but can still zoom in from a long distance - because it has a tiny, tiny sensor you're essentially cropping the image. This is done optically, not in camera or anything like that, so you still get a full image, it's not like cropping in Photoshop. For the 4/3 system, a 70-300mm lens will be equivalent to a 140-600mm lens on 35mm full frame. Not the best if you're 5' from the subject, but great if you are 200' or more from the subject.
Normally small sensors have noise issues, but in your case since you're shooting mid day in an arid region, that's not going to be a problem. Keep your ISOs low and you'll be fine.
I don't think I've ever said this, but in this case I think the 4/3 system is definitely right for you. If I had my choice, I'd go with your initial idea with the OMd: it's weatherproofed, ergonomically, smallish, and hell, man, it looks cool!
Here is a lens you might want to research:
