These little birds are pretty quick to flit into and out of the bird feeders, so it was just luck that I got video more than a few seconds long of this one who actually seemed to be watching me through the window. He then grabbed a sunflower seed, and landed on a branch in the little tree behind the feeder and showed what he has to go through to get to the seed inside the husk to make a meal out of it.
