I can see why you picked Carolina wren for #8. It's incorrect but reminds me that I do not have a fine definitive shot of that species from which I can extract an eye for an eye-D. Actually Dinu, I thought everyone would get #8. While not uncommon, many people have never seen one because they are never still enough around still water to catch a glimpse of this sort-of-warbler.
#7 is indeed a female Northern Shoveler. I don't seem to encounter a female of the species very often.
#5 is a tree hugger (to me) but not a peckerhead, although it has a respectably long probing tool, but not a noggin that could absorb the kind of pounding a Downy might experience, even for a small woodpecker. I thought that the hint of a coal-black eye surrounded by white would give it away but I guess my subjective view is not shared by all.
#6 is a very common bird with a dark(ish) head and that crazy splash of white around the eye that almost comes across as malignant in its ragged outline ... sort of invasive, if you know what I mean. There were so many of these around this spring and well into the summer but now I must admit to seeing very few, even though they might even appear in winter, from time-to-time. The bird providing an eye here was sitting in a nest that was concealed under the densely leafed low hanging bough. I just lifted the bough with one hand, said "allow, allow, allow" ... and click. I then lowered the bough as went on my way.
#6B is also quite common if you are in the right environment, It's by far the biggest bird yet depicted as an eye-D.
