Black and White Warbler

The Black and White Warbler acts more like a Nuthatch than a Warbler. It clings onto tree trunks gleening them for insects. A small object zoomed past me like a bullet while I was hiking in the Big South Fork River and Recreation Area in Northern Tennessee.  I didn't see where it landed, so I just aimed my camera in the general area where I thought it might have gone, and shot without even knowing what I was focussing on.  Upon looking at my photo images and zooming in on this frame, I found the little guy clinging to a tree. Not a great picture as far as clarity is concerned , but I marvelled that I even got an image at all.
