Here is a small series of bird images made last winter. All of these were taken through a double-paned window with a Panasonic FZ20. (Tip: keep windows clean - *smile*)
The above and next two images are of a Junco - one of my favorite little birds.
This is a female red-bellied woodpecker. The male has a solid red streak from its beak to the back of its head, while the female's streak is broken with a pale gray band.
