I think this is very close to being a really good haiku. However, you have incorrectly spelled lightning, whether this was out of an attempt to lengthen the syllables of the line, or for some other purpose, both efforts would be miss founded as adding an extra syllable into your line would disqualify this as a haiku.
I would also suggest perhaps capitalizing the final line, truly making it stand out and have us realize that this thing you are describing is your neighbors birch tree.

But all in all? This was a good haiku.
