I lived in Hawaii for years, years ago, and I frequently return to visit friends and do some birding. I agree that you'll probably get more out of Oahu birding if you do a bit of research beforehand.
I also agree that a private tour, as described in the postings above, may be the best way to see the forest endemics - and the safest. the Hawaiian forest birds are in the more mountainous areas - some in the same areas that are patronized by pig hunters and growers - and can have mudslides and flash floods.
Two areas that you may enjoy without a guide > Waimea Falls on the North Shore. This place has changed ownership over the years, but the last time I was there it was being managed by Audubon. Lots of introduced species with introduced tropical flora - with weak and outdated exhibits of Hawaiian endemics. This was about five years ago, and I believe Audubon had just started managing the place, so maybe some things have changed.
> James Campbell NWR, also on the North Shore close to Kahuku. It's closed most of the year, but opens sometime in October/November and closes again in Feb, I think. There is a ranger or guide there on some days (maybe all the time now). Their website should provide such details. and here is a link
Link to Audubon with some info.
If the price is right, I'll be visiting HI in November as well. I'd like to get to the JCampbell NWR to see bristle-thighed curlews.
Not sure of your budget and time restraints, but interisland airfares are usually reasonable and birding on Kauai and Big Island can be very rewarding.
One more thing I should mention: November is high surf season, with lots of surfers in the North Shore area - be careful around the ocean waters, and be careful of where you leave your gear.
