Seeing as almost everyone is agreeing I thought I'd play devils advocate with much better birders than myself so go easy! Isn't the lack of yellow coloration in the throat seeming to lean toward Warbling Vireo. From the intensity of yellow on this bird it seems the richer yellow areas are the undertail coverts. I was always lead to believe that you looked for intensity of coloration of yellow on these vireos. Philly should be in the throat and yellower in general, Warbling on the undertail coverts and flanks (as with this bird - the throat seems completely white - the undertail coverts pretty bright). With the Warbling (as is the case with this bird), a dark area in the lores can be apparent in as can a seemingly contrasty cap.

All good points by Luke, and I don't think there's any doubt that based on
the photos available the IDs suggested are just that - suggestions. I'm not
sure the bird can be positively identified from the photos. One factor that
comes into play in these kind of photo ID exercises is monitor variation.
There's no way of knowing if fairly subtle colors seen by one observer on
their monitor are the same as those seen on another. From my point of view,
the yellows were so negligible on my monitor that I didn't really give them
a lot of weight. The apparent dark lores (better for Philly) are the best
feature to me. I suspect the photo angle from below downplays any yellow
that might be present on the throat-upper breast. I think Dave alluded to
the fact that Philly shows its least intense yellow in spring (sometimes
almost lacking), so that complicates using that feature at this time of
year. The yellow is much more prominent in fall.

One other subtle feature is that Philly is somewhat smaller-billed that
Warbling (especially the eastern race of Warbling, which is slighthly larger
than western race). I get a small-billed impression on this bird, but again
that's subtle and hard to be sure about on a lone bird.

Would I be shocked if another photo of this bird popped up showing it to
clearly be Warbling? No. I'm just leaning toward Philly based on what we've
got to work with.

I think Luke is correct with his ID as Warbling Vireo.  aaaaaathe angles are
terrible to assess anything but the bill is longer than what I expect a
Philadelphia should show and appears broader-based.  It also doesn't appear
to be as relatively large-headed as Philadelphia appears to me.  Philly
Vireo, because of its small size, large head and short bill, looks a bit
bull-headed, like a Loggerhead Shrke...I don't get this from this bird.  I
see a long-billed smaller headed bird with fairly pale eye arcs and a dark
loral line that is variably present on the photos but that is not out of the
possible range of dark in the lores for Warbling Vireo.  In fact, in the
first image, the dark does not seem to make it through the lores.  Again, I
think Luke is right but as Greg says, if an image surfaces that show this to
be a Philly Vireo...

As to Luke's questions about Bicknell's Thrush, there are banding records (I
have banded at least one) and credible sight records (including heard
vocalization) from Connecticut.
