Nope, not a little brown bird. This one is a little brown butterfly called Henry's Elfin, Incisalaia henrici or Callophrys henrici depending on which authority you use. There was some really pretty green on the wings that didn't show up in this photograph. Too bad.
These butterflies fly here in the early spring and though not particularly uncommon, they can be hard to spot. Being little and brown they tend to go unnoticed. Evergreen hollies seem to be a favored host plant.
