While all of my hummingbird photography is done 'in nature' - i.e. they are completely free and wild, only sometimes do I actually shoot them in front of foliage. This is for several reasons: 1) Everybody else does that - the internet abounds with hummingbirds drinking at pretty flowers and 2) I often find the foliage background very distracting, removing attention from the exquisite beauty of these tiny birds, as you can see in a few of these images. Of course, you may disagree, and that is perfectly fine :)
