I snapped some closeups of the hummingbird feeder this evening--talk about nervous birds! Of course, I was less than 3 feet away from the bulb--so I suppose I understand, but it's not the first time I've sat in front of the feeder waiting for a bird to show up.
But these guys they take the cake, really, in-out-gone, back-forth, up-down, trying to get a taste from the back (or maybe he's hiding?)...and a stop action from the side..
Check it out.
