A Route of Evanescense

I was not sure of the true meaning of this poem until I researched it on the internet. After I found out it was about a hummingbird, I worked to break it down line by line. I believe it speaks of a humming bird that is on a "route" to retrieve nectar. I depict this because it says "And every Blossom on the Bush Adjust its tumbled Head" (Dickinson 5-6). This, I think, talks of the Hummingbird bending its head down into a flower to retrieve nectar. If I would have never looked this poem up, I am not sure I would have been able to determine it's true meaning. This proves how tricky poetry often is, for me anyway.
