Lin, love your photos. Yes, the Yellow Bellied Sapsuckers are in your area as well. They are throughout FL in the winter.

I have to say though that they surely have some kind of camouflage! Look at the photos I took --- if it weren't for the bright red it would be very difficult to spot them. Movement would be the only other way but these guys don't move a whole lot. When they get a spot, they stay there for a while. It's amazing how they blend right in with that sycamore trunk.
Becky, great shots! Can't wait to see the video.
Elaine, despite the bright colors on the male painted buntings, it will blow you away how well they blend with the surroundings even on a feeder. You would think they would stick out like a sore thumb but they almost disappear. As to their shyness, they are in the beginning, extremely shy of *you* as well as everything else. If you move past a window, they will go to cover. They will get used to the humans that feed them but it does take time & patience.
