Seems like I will be back in Princeton in early December and will have some free time over the weekend of 5th and 6th to catch up with some birds.
Species that from the Sibley guide might be in-range and possible to see which would be new for me would be :-
Wood Duck
Red-headed Woodpecker
Hairy Woodpecker
Brown Creeper
White-breasted & Red-breasted Nuthatches
Golden-crowned Kinglet
Yellow-rumped Warbler
Field Sparrow
Pine Siskin
Any suggestions would be appreciated.

I bird Princeton quite a lot and can comment on the below:
Wood Duck -- fairly common at the Pond in the Refuge
Red-headed Woodpecker -- I have yet to see one in Princeton for the past 5 years (but that could be my bad luck).
Hairy Woodpecker - Failry common, though not as common as downy. There are also quite a few Pileated around and can be heard calling regularly at the refuge.
Brown Creeper - Common in the refuge in the winter. They can be seen running up and down tree trunks like little mice. Usually not hard to find in the winter.
White-breasted & Red-breasted Nuthatches - White-breasted, common. Red-breasted: I have yet to see one at the refuge, but have seen them in the area (mostly at my backyard feeder).
Golden-crowned Kinglet - Common at the refuge and can be found traveling with Chickadees, Titmice and Nuthatches. I usually find these birds traveling together, so if you hear Chickadees or Titmice (both quite vocal), chances are, Kinglets or White-breasted Nuthatches will be in tow.
Yellow-rumped Warbler - Pretty common as well, but more can be found at the shore (these are abundant at Sandy Hook). I see more of these at the Refuge-end of the Institute woods.
Field Sparrow - I see these more frequently at the "Pole Farm" in Lawrenceville, about 5 minutes away from Princeton. Pole farm is also good for wintering short-eared owls, meadowlark and harriers.
Pine Siskin - I see more of these at my feeder than I do the refuge. Not common, but sometimes present. I have not seen any yet this season.
