Hi everyone, featherbrain asked me to write the answer to Quiz 10. Sorry I'm a bit late in getting it posted. I had written a very lengthy, detailed answer out, then forgot to send it to my home computer. So, I had to write a new, more improvised version here at home. Argh!
First of all, we can see that this bird is clearly a Passerine, or perching bird. It has an obvious large white eyering, clean white underparts/undertail coverts, dark crisp streaks on the flank, and is plain brown above. It brings to mind thrushes, Mimids (catbirds, mockingbirds, and thrashers), maybe pipits, wood-warblers, and some sparrows.
Going through this methodically, we'll start with thrushes (Turdidae). The only North American thrushes that show contrasting dark markings on the flank are Fieldfare and Wood Thrush. Fieldfare is a very rare visitor from Eurasia, and lacks the prominent eyering shown on the quiz bird, not to mention that Fieldfare doesn't even resemble the quiz bird, plumage-wise. Wood Thrush is a good guess, but they clearly have individualized spots on their flanks. The quiz bird has long streaks, unlike a Wood Thrush.
The quiz bird's tail is simply too short to be any species in the Mimidae family, that's for sure. And any pipit (Motacillidae) would show at least weak wingbars, which are obviously non-existent in the quiz bird. Plus, pipits aren't likely to be found perching in a tree as such.
As we all know, warblers (Parulidae) are a large, complex and sometimes frustrating group, but thankfully, there are only a few North American species that have the combination of dark flank streaks, no wingbars, and no yellow coloring like the quiz bird. They are the Seiurus trio, Ovenbird, Northern Waterthrush, and Louisiana Waterthrush. The waterthrushes can be eliminated by the fact that the quiz bird has no white supercillium. Ovenbird matches the quiz bird very well, in fact, there is basically nothing that points away from it being an Ovenbird.
Fortunately, the only sparrow with an eyering like that is the Vesper Sparrow. Vesper Sparrows show a much more complex wing and head pattern, and their flank streaks aren't as strong as on the quiz bird.
So, we can confidentally say it is not a thrush, Mimid, pipit, or sparrow, and the only warbler that shows the combination of markings shown by the quiz bird is Ovenbird. If you disagree with this analysis, feel free to discuss.
featherbrain photographed this Ovenbird (Seiurus aurocapillus)...somewhere! 
Tallies of incorrect guesses
Wood Thrush - 2
Louisiana Waterthrush - 1
Congratulations to these users who answered correctly!

Hi Guys!
Thanks to josh and tim for taking over while I was gone. I am back and was going through my (hundreds, literally) of emails and found that nsteika sent me a personal message with the correct answer, so congratulations also to nsteika!

Hi all, I'm very sorry about how late this answer is. I've had little time to write it up, so I'm also sorry for the thrown-together-ness of the answer.
Everyone who gave a specific answer this week was correct, so I shouldn't have to do much explaining. The photo is small, making it difficult to pick out details, but we can make out the notched tail and upright posture, excellent features pointing us towards the finches. It brings to mind female Purple, Cassin's, and House Finches, young crossbills, redpolls, and Pine Siskin.
Purple Finch is difficult to eliminate, but a variety of factors rule it out. The dark streaks on the mantle resemble a female Eastern Purple Finch's, but if this was indeed an Eastern Purple Finch, a white supercillium would be visible. If this was a Pacific Purple Finch, the mantle stripes wouldn't be near as dark and strong. Also, a Purple Finch would be quite rare in Montana, where the photo was taken.
A female Cassin's Finch has the strong dark mantle streaks, as well as flank streaks, like the quiz bird. However, a Cassin's crisp flank streaks are against a clean bright white. On the quiz bird, the streaks are against a dirty brownish off-white.
And, for the last of the Carpodacus finches, House Finch can be eliminated by the fact that the quiz bird has crisp, dark mantle stripes, unlike the poorly defined blurry mantle of female House Finches.
I may not be correct on this, but I'm fairly certain that neither North American crossbill species sits in such an upright posture, therefore ruling them out. If I'm incorrect, please inform me.
Either redpoll (Common and Hoary) would clearly have a pale, if not white rump, clearly lacking in this bird. That leaves us with Pine Siskin, a semi-nomadic, medium-sized Carduelis finch. The crisp mantle stripes and dark flank streaks against a dirty "background" of a Pine Siskin match the quiz bird perfectly.

None!

I think that joshc will be posting the next quiz, though I'm not certain. In any case, it shouldn't be too long before it will be. Thanks!

Sorry folks, but I am having real troubles with the picture files, and uploading/dowloading of pictures on my computer. I guess the new quiz will be when Featherbrain gets back! Sorry.....
Good Luck Birding Josh

Re: Weekly (more or less) Photo Quiz!
Okay, finally here's the next quiz. No location given! 
Unfortunately, you only have the rest of today, Thursday, Friday, Saturday, and Sunday morning to answer. I hope that doesn't cause any problems. Please email your answer and Whatbird username to featherbrain1@gmail.com.
Thanks, and good luck!

Well, either this one was super difficult, super easy, or there wasn't enough time to answer, but in any case, only 3 people replied. Sorry about the delay in getting the photo posted, and sorry for the delay in getting this answer posted! I had an unusually busy Sunday.
I personally thought this quiz was fairly easy (compared to previous, at least!). We can see that this is an overall yellow, generally unmarked Passerine actively gleaning insects. It has a noticeable white undertail, and a defining olive "hood" curling around its auricular patches and up onto its crown. Wood-warblers is what first comes to mind, maybe vireos too.
The overall plain yellow-and-green plumage of the quiz bird is somewhat distinct among wood-warblers (Parulidae), with only a handful of species, them being (in taxonomic order) Tennessee, Orange-crowned, Yellow, and Prothonotary Warblers, Common and Gray-crowned Yellowthroats, Oporornis, (Mourning, MacGillivray's, Connecticut, and Kentucky), Hooded, and Wilson's Warblers. Okay, okay, I know that's more than a handful, but thankfully most of these are easily eliminated.
To kick things off, we'll swipe out Tennessee, Orange-crowned, Yellow Warblers, Common and Gray-crowned Yellowthroats, the Oporornis quartet, and Wilson's Warbler with that distinct white undertail shown on the quiz bird. There are minor details that can be picked out in each of those species, but I wanted to save space and time.  If you are easily confused like me, I'll inform you that that leaves us with Prothonotary and Hooded Warblers. Prothonotary does have a partially white tail, but also a contrasting white belly, lacking in the quiz bird. A Prothonotary would also have a much, much more chunky build and a shorter tail. Last we have Hooded Warbler, which, not surprisingly, has a white undertail! The olive "hood" also matches perfectly, as does the plain yellow-and-green overall color.
I know we already eliminated Wilson's Warbler by the undertail, but I thought I'd go more indepth. I find that the easiest and "safest" way to tell the similar Hooded apart from Wilson's is the auricular patch, the feathers that cover the ear just "behind," or caudal to the eye. In a typical Hooded Warbler, these feathers are the same bright yellow as the rest of the face, as shown here. In a Wilson's Warbler, the auriculars are olive-green colored, like the nape, mantle, and wings, as shown here (pay no attention to the black cap, we're talking about young and female birds, not easy-to-ID males  ).
If you thought it was a vireo, well, I'm afraid you were incorrect. The only North American vireo with that bright of yellow is the Yellow-throated Vireo, which shows bright white wingbars. Not a vireo, that's for sure!
featherbrain photographed this (1st year?) female Hooded Warbler (Wilsonia citrina) in his yard (I think....)
Incorrect guesses
Wilson's Warbler - 1

I'm...not sure about what's going on with Quiz #13. Maybe I can dig up another more-difficult quiz. Sorry all, thanks for your patience!

Alright guys, sorry for the major delay, I've been traveling alot lately, and am getting ready to go again!
A big thanks to tim.birdboy and joshc for taking over!
Here's Quiz 13! I'm thinking that we should start a scoring system to get things more competitive here, we won't start on this one because I'm still coming up with ideas, any suggestions welcome. Once I do start the scoring system I will post a reminder in the Help me ID a bird area since everybody browses that area constantly (it seems).
Good Luck!

My theory: the easier the quiz, the more popular! This may have been our biggest turn out, with 9 people guessing.
Here we have a small-looking Passerine showing us its pretty little blue behind. Noticeable field marks are the grass-green mantle, and bright white wingbars. To put it simply, the only North American bird species showing these three characteristics (blue upperparts, green mantle, white wingbars) are Tropical and Northern Parula (I went through every North American bird species just to be sure  ). Unfortunately, we don't have a good view of the quiz bird's face, so we can't discern if there are eye arcs or not. But seeing that no yellow is visible on the flank or sides, we are pretty safe in saying that it's a Northern Parula from this photo.
