Well, now seriously: in the last few years I go only with my birding lens - it's heavy (at lest for me) and taking additional lenses for hiking makes no sense, it is doing good enough job for me: when there are no birds you click on every thing that looks interesting...
Many times it has the advantage over the 105mm macro because the creatures are so shy.
On other cases if you shoot a flower on the tree with macro lens you have to hike with good leader on your back - anybody tried this? I didn't

! Or simply the object is so far and there is no way to get closer because of the brush around.
And some times you just don't want to be close to your objects by safety reasons...
Most of these photos were posted already on different topics of this forum. I have many others that don't fit the recent restrictions in the Forum (and on this topic the restrictions are even more strickt) and I'm so lazy to work on them.
In my own terminology I call all this "close ups".
The last photo is taken with 105mm macro lens, the flower is so tiny for the magnification my birding lens can produce, and it for me is a real macro. Now put this flower in controlled conditions (no wind, no canopy that change the light) and stack it in several shoots (I just don't shoot in controlled conditions) - and you will see what the macro lenses can do...
