Hi Larry.
I'm late spotting this thread. Two words. Cape May. Me and a gaggle of other Brits lived there throughout the Nineties. In fact I was just digitizing some of our old log books this morning. I just glanced at your list briefly and saw at least a dozen familiar names that would be pretty easy on Cape May 'island'. I could add a few others within ten mile radius. Apart from anything else, it's a very pretty place, though a bit on the expensive side (you have to pay to go on the beach!). (My mother and grandmother came on holiday and really liked it - lots of old Victorian architecture, tree-lined streets etc) There's Cold Spring Campground on Cape 'island' itself: breeding Eastern Screech Owl and Wild Turkey within walking distance; and I think Barred Owl now breeding there, though could find out if you were really interested. Should still be one or two Piping Plovers around - they breed, but tend to depart fairly early - Saltmarsh, Seaside and Field Sparrows all breed within 3-4km radius. And so on... Other than that, there is always the chance of migrating Warblers and Waders around, though maybe only 1-2 of the former included in your hit list?
As others have said, August is hot and humid almost anywhere in the States, and you will undoubtedly see a lot more mozzies than birds. Cape May does at least provide some coastal sea-breeze relief from the hot interior - though still very humid compared to what we are used to in UK.
I glanced back at the list and totted up 20-22 birds that would be feasible in a 10-mile radius of Cape May at that time of year, though some, such as Acadian Flycatcher, wouldn't necessarily be that easy on your own at that stage of the breeding cycle - indeed the same goes for Owls and Whip-poor-wills, for example, that may not be calling. I've seen migrant Veeries at Cape May by late August in some years - though again, there'll just be the odd one or two; not guaranteed.
