It may not be obvious at first, but the picture above is a collage of 4 shots of the same (please be right) yellow-rumped warbler.
If my ID is wrong somehow, please correct me, but he does have a yellow rump and it is the same individual in each shot. I like warblers and a live oak tree full of them is a magical thing, but I generally enjoy them without knowing exactly who they are ... and any useable warbler photograph is just a case of serendipity and some luck.
This sprite was working the leaf litter at Manatee Springs last weekend in a frantic, frenetic, food-finding frolic.
Simply by folding his wings and holding still he would disappear among the dead leaves, a great example of cryptic coloration.
Now, I must unfold my wings and get to work.
